By setting a three-axis driving mechanism in cooperation with a multi-degree-of-freedom wire drawing head mounting mechanism composed of first to fourth mounting brackets, multi-angle flexible adjustment of the wire drawing head in three-dimensional space is realized. Among them, the second mounting bracket can rotate around the X-axis, the third mounting bracket can be adjusted by moving along the Y-axis direction, and the fourth mounting bracket can rotate around the Y-axis, so that the wire drawing head mounted on the fourth mounting bracket can perform rotary wire drawing processing on the surface of the aluminum plate at different angles, different depths and different texture directions according to the preset path and speed. Therefore, texture patterns with different depths can be engraved on the surface of the aluminum plate according to the design pattern, providing a basic texture layer with three-dimensional sense for the subsequent screen printing process.

Description

Technical Field

[0001] This invention relates to the field of automotive trim processing equipment, specifically to a rotary wire drawing machine, which is particularly suitable for surface texture processing of automotive aluminum trim parts. Background Technology

[0002] With the upgrading of automobile consumption, consumers have increasingly higher requirements for the quality and aesthetics of automotive trim. Due to its metallic texture, lightweight and good formability, automotive aluminum trim has been widely used in the design of trim for mid-to-high-end automobiles.

[0003] Currently, most automotive aluminum decorative parts on the market use screen printing to present the design pattern on the surface of the aluminum plate. This involves printing ink or paint onto the aluminum plate using a screen printing plate to form the desired decorative pattern. This processing method can achieve relatively fine planar patterns, is a mature technology, and has relatively low cost, so it is widely used in the industry.

[0004] However, the aforementioned screen printing technology has significant shortcomings: it can only present a two-dimensional planar effect on the aluminum plate surface, and the resulting decorative patterns lack a sense of three-dimensionality and layering, resulting in insufficient visual impact. As consumers' aesthetic requirements for trim pieces continue to increase, simple two-dimensional planar decoration is no longer sufficient to meet the styling design needs of high-end automotive brands, especially in terms of surface texture, light and shadow effects, and three-dimensionality, where traditional screen printing processes are clearly deficient.

[0005] Therefore, how to provide a processing device that can process textured patterns with a three-dimensional effect on the surface of aluminum plates has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] In view of the above problems, this application provides a rotary wire drawing machine to solve the technical problems involved in the background art.

[0007] To achieve the above objectives, this application provides a rotary wire drawing machine, including a machine base and a three-axis drive mechanism disposed on the machine base. The upper surface of the machine base is a processing surface for placing the material to be processed, and includes a wire drawing head mounting mechanism and a wire drawing head mounted on the wire drawing head mounting mechanism.

[0008] The wire drawing head mounting mechanism includes a first mounting bracket, a second mounting bracket, a third mounting bracket, and a fourth mounting bracket;

[0009] The first mounting bracket is fixedly connected to the three-axis drive mechanism, and the second mounting bracket is rotatably mounted on the first mounting bracket around a preset horizontal X-axis direction;

[0010] The second mounting bracket is provided with a strip mounting plate arranged along a preset horizontal Y-axis direction;

[0011] The third mounting bracket is mounted on the strip mounting plate and can move along the extension direction of the strip mounting plate. The third mounting bracket is provided with a first locking structure, which is used to lock the third mounting bracket in a horizontal position on the strip mounting plate.

[0012] The fourth mounting bracket is mounted on the third mounting bracket and can rotate around a preset horizontal Y-axis.

[0013] The wire drawing head is mounted on the fourth mounting bracket, with the processing end of the wire drawing head facing downwards and located directly above the upper surface of the machine base.

[0014] Unlike existing technologies, the technical solution of this application achieves flexible multi-angle adjustment of the wire drawing head in three-dimensional space by setting up a three-axis drive mechanism in conjunction with a multi-degree-of-freedom wire drawing head mounting mechanism composed of first to fourth mounting brackets. Specifically, the second mounting bracket can rotate around the X-axis, the third mounting bracket can move and adjust along the Y-axis, and the fourth mounting bracket can rotate around the Y-axis. This allows the wire drawing head mounted on the fourth mounting bracket to perform rotary wire drawing processing on the aluminum plate surface at different angles, depths, and texture directions according to a preset path and rotation speed. As a result, texture patterns of varying depths can be engraved on the aluminum plate surface according to the design graphics, providing a three-dimensional texture layer for subsequent screen printing processes. Ultimately, this gives automotive aluminum products a 3D stereoscopic visual effect, overcoming the shortcomings of traditional screen printing which can only present a two-dimensional planar effect, enhancing visual impact, and meeting the increasingly sophisticated aesthetic design requirements of automotive decorative parts.

[0015] In one embodiment of the present invention, the upper part of the first mounting bracket is fixedly connected to the three-axis drive mechanism, and the lower horizontal sides of the first mounting bracket are respectively provided with outwardly extending sidewalls, and the two sidewalls are arranged opposite to each other and parallel to each other.

[0016] The second mounting bracket is horizontally disposed between the two side walls. A connecting shaft is provided at one horizontal end of the second mounting bracket. A first bearing is embedded in one of the two side walls. The connecting shaft passes through the first bearing. A drive shaft is provided at the other horizontal end of the second mounting bracket. A second bearing is embedded in the other side wall. The drive shaft of the external drive motor passes through the second bearing and is fixedly connected to the other horizontal end of the second mounting bracket.

[0017] In one embodiment of the present invention, the upper end of the third mounting bracket is provided with a first slot with the opening of the first slot facing downwards, and the lower end of the third mounting bracket is provided with a second slot with the opening of the second slot facing upwards. The first slot and the second slot together form a receiving space for accommodating the strip mounting plate.

[0018] In one embodiment of the present invention, the first card slot and the second card slot are both provided with the first locking structure.

[0019] In one embodiment of the present invention, two or more third mounting brackets are spaced apart along the extension direction of the strip mounting plate, and each third mounting bracket is provided with a fourth mounting bracket.

[0020] In one embodiment of the present invention, the number of the third mounting brackets is eight.

[0021] In one embodiment of the present invention, the fourth mounting bracket is provided with at least one arc-shaped adjustment groove, and the second locking structure passes through the arc-shaped adjustment groove and connects to the third mounting bracket, so as to allow the fourth mounting bracket to rotate around a virtual axis in the loose state, and to fix the fourth mounting bracket and the third mounting bracket relative to each other in the locked state.

[0022] In one embodiment of the present invention, there are two arc-shaped adjustment grooves, namely an upper arc groove and a lower arc groove; the upper arc groove and the lower arc groove are spaced apart from each other and arranged concentrically.

[0023] In one embodiment of the present invention, the three-axis drive mechanism includes a gantry, an X-axis drive mechanism, a Y-axis drive mechanism, and a Z-axis drive mechanism;

[0024] The X-axis drive mechanism is mounted on the machine base, the gantry is erected above the machine base and the bottom end of the gantry is mounted on the X-axis drive mechanism, and the gantry can move horizontally along the X-axis when the X-axis drive mechanism is driven.

[0025] The Y-axis drive mechanism is mounted on the gantry, the Z-axis drive mechanism is mounted on the Y-axis drive mechanism, and the first mounting bracket of the wire drawing head mounting mechanism is fixedly connected to the Z-axis drive mechanism.

[0026] In one embodiment of the present invention, the processing surface of the machine base is a marble plane, and the material to be processed is an aluminum plate.

[0056] like Figures 1 to 6 As shown, this embodiment provides a rotary wire drawing machine, mainly used in the rotary wire drawing process of automotive aluminum decorative parts processing. The rotary wire drawing machine includes a machine base 1, a three-axis drive mechanism mounted on the machine base 1, a wire drawing head mounting mechanism, and a wire drawing head 6 mounted on the wire drawing head mounting mechanism.

[0057] The machine base 1 serves as the supporting foundation for the entire equipment, and its upper surface is the processing surface 11, used to place the material to be processed. In this embodiment, the material to be processed is an aluminum plate. During processing, the entire aluminum plate is placed horizontally on the processing surface 11, and the aluminum plate is fixed to the processing surface 11 by vacuum adsorption or clamps to prevent the aluminum plate from shifting during processing.

[0058] In this embodiment, the processing surface 11 of the machine base 1 is a marble plane. Specifically, a marble panel is embedded or laid on the upper surface of the machine base 1, and after precision grinding, a highly flat processing surface 11 is formed. The marble plane has extremely high hardness and rigidity, which can provide flat support for the aluminum plate. The thermal conductivity of marble is extremely low (approximately 2.08 W / (m·K)), far lower than that of metal materials. During the rotary wire drawing process, the wire drawing head 6 continuously rubs against the surface of the aluminum plate at high speed, which will instantly generate a large amount of cutting heat. Since aluminum itself has good thermal conductivity, the heat is easily conducted and diffused rapidly along the plate surface. Using a marble plane as the processing surface 11 can form an effective thermal barrier layer between the aluminum plate and the processing surface 11. On the one hand, the marble processing surface 11 does not easily conduct away the heat generated by the friction of the aluminum plate, avoiding the problem of excessive local temperature difference in the aluminum plate due to excessive or uneven heat dissipation. On the other hand, marble itself has a very small coefficient of thermal expansion, and hardly undergoes thermal expansion and contraction. Even during long-term continuous processing, its processing surface 11 always maintains its initial flatness, providing a constant, heat-independent support reference for the aluminum plate. This effectively suppresses thermal deformation of the aluminum plate during processing (such as warping, wave deformation, etc.), ensuring that the aluminum plate remains in contact with the flat processing surface 11 throughout the entire wire drawing process. This guarantees that the texture depth engraved by each wire drawing head 6 is consistent and the pattern connection is accurate. In addition, the wear resistance and vibration resistance of marble further enhance the long-term stability of the processing surface 11.

[0059] The three-axis drive mechanism is used to drive the wire drawing head mounting mechanism and the wire drawing head 6 on it to achieve precise trajectory movement in three-dimensional space. The three-axis drive mechanism includes a gantry 2, an X-axis drive mechanism 3, a Y-axis drive mechanism 4, and a Z-axis drive mechanism 5.

[0060] The X-axis drive mechanism 3 is mounted on the machine base 1 and is usually arranged along the length direction of the machine base 1 (i.e., the X-axis direction). The X-axis drive mechanism 3 can be a linear guide rail with a ball screw transmission mechanism or a linear motor drive mechanism. In this embodiment, a ball screw pair driven by a servo motor is used in conjunction with a linear guide rail to achieve high-precision linear motion.

[0061] The gantry frame 2 is mounted above the machine base 1, and its two bottom ends are respectively installed on the X-axis drive mechanism 3 (for example, on the slide of the X-axis drive mechanism 3). When the X-axis drive mechanism 3 is driven, the gantry frame 2 can move horizontally along the X-axis. The gantry frame 2 is made of high-strength steel by welding or casting, and has the characteristics of good rigidity and strong load-bearing capacity. It can effectively support the weight of the wire drawing head mounting mechanism and the wire drawing head 6, and remain stable during high-speed movement.

[0062] The Y-axis drive mechanism 4 is mounted on the gantry 2, specifically on the crossbeam of the gantry 2. The Y-axis drive mechanism 4 is arranged along the Y-axis direction (i.e., the direction perpendicular to the X-axis in the horizontal plane), and can also be a ball screw pair driven by a servo motor in conjunction with a linear guide.

[0063] The Z-axis drive mechanism 5 is mounted on the Y-axis drive mechanism 4, specifically on the slide of the Y-axis drive mechanism 4. The Z-axis drive mechanism 5 is arranged in the vertical direction (Z-axis direction) and is used to drive the wire drawing head mounting mechanism to perform lifting and lowering movements. The Z-axis drive mechanism 5 can also adopt a ball screw pair structure driven by a servo motor.

[0064] The first mounting bracket 7 of the wire drawing head mounting mechanism is fixedly connected to the Z-axis drive mechanism 5 (specifically, fixedly connected to the slide of the Z-axis drive mechanism 5), thereby enabling the wire drawing head 6 to move along any trajectory in three-dimensional space through the coordinated movement of the X-axis drive mechanism 3, the Y-axis drive mechanism 4 and the Z-axis drive mechanism 5.

[0065] The wire drawing head mounting mechanism includes a first mounting bracket 7, a second mounting bracket 8, a third mounting bracket 9, and a fourth mounting bracket 10. The first mounting bracket 7 is fixedly connected to the three-axis drive mechanism. The second mounting bracket 8 is rotatably mounted on the first mounting bracket 7 about a preset horizontal X-axis. The third mounting bracket 9 is mounted on the second mounting bracket 8. The fourth mounting bracket 10 is mounted on the third mounting bracket 9 and is rotatable about a preset horizontal Y-axis. The wire drawing head 6 is mounted on the fourth mounting bracket 10.

[0066] Specifically, the upper part of the first mounting bracket 7 is fixedly connected to the three-axis drive mechanism, that is, the upper part of the first mounting bracket 7 is fixedly connected to the slide of the Z-axis drive mechanism 5. The lower horizontal sides of the first mounting bracket 7 are each provided with an outwardly extending sidewall, which is arranged opposite to and parallel to each other. Both sidewalls are vertically arranged plate-like structures, integrally extending from the lower part of the first mounting bracket 7 to the same horizontal side.

[0067] The second mounting bracket 8 is horizontally positioned between the two side walls. A connecting shaft is located at one horizontal end of the second mounting bracket 8, and a first bearing is embedded in one of the two side walls, with the connecting shaft passing through the first bearing. A drive shaft is located at the other horizontal end of the second mounting bracket 8, and a second bearing is embedded in the other side wall. The drive shaft of an external drive motor passes through the second bearing and is fixedly connected to the other horizontal end of the second mounting bracket 8.

[0068] In actual operation, after the peripheral drive motor starts, the drive motor's transmission shaft drives the second mounting bracket 8 to rotate around the horizontal X-axis. During rotation, the connecting shaft engages with the first bearing, and the transmission shaft engages with the second bearing. The two bearings work together to provide support and guidance, making the rotation of the second mounting bracket 8 more stable and precise. By controlling the rotation angle of the drive motor, the tilt angle of the second mounting bracket 8 can be precisely controlled, thereby adjusting the tilt angle of the wire drawing head 6 in the X-axis direction.

[0069] By embedding the first bearing and the second bearing on the two side walls respectively, a stable "double support" structure is formed, which makes the rotation of the second mounting bracket 8 more stable, reduces friction loss and radial runout during transmission, and ensures that the wire drawing head 6 can cut into the aluminum plate surface at a set angle during the rotating wire drawing process, thus ensuring the consistency of texture depth and pattern accuracy.

[0070] The second mounting bracket 8 is provided with a strip-shaped mounting plate arranged along a preset horizontal Y-axis. The strip-shaped mounting plate is a long strip-shaped structure, and its length extends along the Y-axis. The strip-shaped mounting plate can be integrally formed with the second mounting bracket 8, or it can be fixedly installed on the second mounting bracket 8 by bolts.

[0071] The third mounting bracket 9 is mounted on the strip mounting plate and can move along the extension direction of the strip mounting plate (i.e., the Y-axis direction). Specifically, the upper end of the third mounting bracket 9 has a first slot with its opening facing downwards; the lower end of the third mounting bracket 9 has a second slot with its opening facing upwards. The first and second slots together form a receiving space for accommodating the strip mounting plate. During installation, the strip mounting plate is inserted between the first and second slots, so that the third mounting bracket 9 is engaged with the strip mounting plate in a "clamping" manner. This structure, on the one hand, allows for flexible movement and adjustment of the third mounting bracket 9 along the extension direction of the strip mounting plate, facilitating adjustment of the horizontal position of the third mounting bracket 9 according to processing needs; on the other hand, the double-slot structure ensures that the third mounting bracket 9 maintains a reliable fit with the strip mounting plate during movement, preventing deflection or detachment.

[0072] The third mounting bracket 9 is equipped with a first locking structure, which is used to lock the third mounting bracket 9 to a horizontal position on the strip mounting plate. Specifically, the first locking structure can be a locking bolt. In this embodiment, both the first and second slots are provided with the first locking structure. Taking the first slot as an example, a threaded through hole is opened at the upper end of the third mounting bracket 9, which extends to the groove wall of the first slot, and the locking bolt is screwed into the threaded through hole. When locking is required, the locking bolt is tightened so that its end abuts against the upper or lower surface of the strip mounting plate, thereby fixing the third mounting bracket 9 to the strip mounting plate. The first locking structure is provided on both the first and second slots, realizing synchronous locking from top to bottom. Compared with setting the locking structure at only a single position, this double-sided locking method can more firmly fix the third mounting bracket 9 to the strip mounting plate, effectively preventing the third mounting bracket 9 from shifting position due to vibration or cutting force during the rotary wire drawing process.

[0073] In this embodiment, two or more third mounting brackets 9 are spaced apart along the extension direction of the strip mounting plate. Each third mounting bracket 9 is equipped with a fourth mounting bracket 10, and each fourth mounting bracket 10 is equipped with a wire drawing head 6. Preferably, there are eight third mounting brackets 9, that is, eight wire drawing heads 6 are installed in a row at intervals on the strip mounting plate. The eight wire drawing heads 6 are arranged side by side, which can simultaneously complete the rotary wire drawing of eight texture lines or eight processing areas in one processing stroke, significantly improving processing efficiency. For the mass production needs of automotive aluminum sheet parts, the eight-head parallel processing method effectively shortens the processing time per unit product, increases production capacity, and at the same time ensures the consistency and uniformity of the texture processed by different wire drawing heads 6.

[0074] The fourth mounting bracket 10 is mounted on the third mounting bracket 9 and can rotate around a preset horizontal Y-axis. The fourth mounting bracket 10 has at least one arc-shaped adjustment groove. A second locking structure passes through the arc-shaped adjustment groove and connects to the third mounting bracket 9, allowing the fourth mounting bracket 10 to rotate around a virtual axis in the loosened state and fixing the fourth mounting bracket 10 and the third mounting bracket 9 relative to each other in the locked state. Specifically, the second locking structure can be a locking bolt, which passes through the arc-shaped adjustment groove and screws into a threaded hole on the third mounting bracket 9. When an angle adjustment is required, the locking bolt is loosened, allowing the fourth mounting bracket 10 to rotate around the virtual axis (i.e., the axis containing the center of the arc-shaped adjustment groove) to the desired angle. Then, the locking bolt is retightened to fix the fourth mounting bracket 10 onto the third mounting bracket 9.

[0075] In this embodiment, there are two arc-shaped adjustment grooves, namely an upper arc groove and a lower arc groove, which are spaced apart and arranged concentrically. The two concentric arc grooves are connected to the third mounting bracket 9 through two second locking structures to form a "double-point locking" fixing method. Compared with the design of a single arc groove, the two concentric arc grooves can provide a more stable guiding effect during angle adjustment, preventing the fourth mounting bracket 10 from tilting during adjustment; at the same time, in the locked state, the upper and lower locking points share the force, which significantly improves the vibration resistance and torsional resistance of the wire drawing head 6 during processing.

[0076] The wire drawing head 6 is mounted on the fourth mounting bracket 10, with its processing end facing downwards and located directly above the upper surface (i.e., processing surface 11) of the machine base 1. The wire drawing head 6 typically includes a rotary drive assembly (such as a pneumatic or electric motor) and a wire drawing cutter or wheel mounted on the output end of the rotary drive assembly. The rotary drive assembly drives the wire drawing cutter to rotate at high speed around its own axis. When the wire drawing cutter contacts the aluminum plate surface, it forms textured marks on the aluminum plate surface through rotary cutting action. The specific structure of the wire drawing head 6 is well-known in the art and will not be described in detail here.

[0077] The following describes in detail the working process and principle of the rotary wire drawing machine in this embodiment, taking the rotary wire drawing process of automotive aluminum decorative parts as an example.

[0078] First, preparations and parameter settings are performed before processing. The aluminum plate to be processed is placed flat on the marble processing surface 11 of the machine base 1 and fixed by vacuum adsorption or mechanical clamps. According to the product design requirements, the motion path of the wire drawing head 6, the corresponding rotation speed of each path segment, and the cutting angle of the wire drawing head 6 are set in the CNC system. The cutting angle is set through two degrees of freedom: on the one hand, by controlling the rotation angle of the external drive motor, the second mounting bracket 8 is rotated around the X-axis to the required tilt angle, thereby adjusting the tilt angle of the wire drawing head 6 in the X-axis direction; on the other hand, the second locking structure on the fourth mounting bracket 10 is released, allowing the fourth mounting bracket 10 to rotate around the Y-axis to the required angle and then lock, thereby adjusting the tilt angle of the wire drawing head 6 in the Y-axis direction. Through the combined adjustment of the above two degrees of freedom, the processing end of the wire drawing head 6 can act on the surface of the aluminum plate at any spatial angle, meeting the design requirements of different texture directions. At the same time, according to the processing needs, the Y-axis position of each third mounting bracket 9 is adjusted along the strip mounting plate and locked and fixed by the first locking structure, so that multiple wire drawing heads 6 are arranged at predetermined intervals in the Y-axis direction.

[0079] Then, the rotary drive assembly of the wire drawing head 6 is activated, causing the processing ends of each wire drawing head 6 to rotate at high speed around its own axis. Simultaneously, the CNC system controls the three-axis drive mechanism to move along a preset path: the X-axis drive mechanism 3 drives the gantry 2 to move horizontally along the X-axis, the Y-axis drive mechanism 4 drives the Z-axis drive mechanism 5 to move horizontally along the Y-axis, and the Z-axis drive mechanism 5 drives the wire drawing head 6 mounting mechanism to move up and down along the Z-axis. Under the linkage of the three axes, the processing ends of the wire drawing head 6 move on the surface of the aluminum plate along the preset path, simultaneously performing rotary cutting on the surface to carve out the texture pattern corresponding to the designed graphic. Because the tilt angle of the wire drawing head 6 is adjustable and the processing path is precisely controlled by the three-axis drive system, the wire drawing head 6 can carve textures of different directions, depths, and shapes on the surface of the aluminum plate, forming a surface effect with rich layers and a three-dimensional feel.

[0080] After the rotary wire drawing process is completed, the aluminum plate is removed from the machine base 1 and proceeds to the next process. Then, through screen printing, the pattern is refined on the basis of the texture formed by the rotary wire drawing. After multiple screen drawing and cleaning steps, the 3D effect is gradually presented. Next, through the blanking process, the parts on the aluminum plate are cut out one by one. Finally, through the injection molding process, the parts are injection molded into finished products.

[0081] During the aforementioned rotary wire drawing process, the large amount of cutting heat generated by the high-speed friction between the aluminum plate and the wire drawing head 6 is effectively blocked by the marble processing surface 11, preventing the aluminum plate from warping and deforming due to uneven heating, and ensuring the flatness and dimensional stability of the entire aluminum plate during processing. At the same time, the high rigidity and vibration resistance of the marble processing surface 11 provide stable support for the aluminum plate. Combined with the high-precision motion control of the three-axis drive system, it ensures that the texture depth engraved by each wire drawing head 6 is consistent and the pattern connection is accurate, significantly improving the product yield.

[0082] In summary, the rotary wire drawing machine provided in this embodiment, through the cooperation of a three-axis drive mechanism and a multi-degree-of-freedom wire drawing head mounting mechanism, achieves flexible multi-angle adjustment and precise trajectory control of the wire drawing head 6 in three-dimensional space. This enables the processing of three-dimensional textured patterns on the surface of aluminum plates, providing richer decorative effects for automotive aluminum products. Simultaneously, the inclusion of a marble-like processing surface 11 effectively solves the problem of heat-induced deformation of the aluminum plate during rotary wire drawing, ensuring processing accuracy and product quality. The parallel arrangement of multiple wire drawing heads 6 significantly improves processing efficiency and demonstrates promising prospects for industrial applications.

[0083] In other embodiments of this example, the number of third mounting brackets 9 can be set to two, three, four, five, six, ten, or more, and is not limited to eight, depending on actual processing needs. The specific number of third mounting brackets 9 depends on the size of the aluminum plate, the complexity of the product texture pattern, and production capacity requirements, and those skilled in the art can make a reasonable selection based on actual needs.

[0084] In other embodiments of this example, the three-axis drive mechanism can also adopt other structural forms, such as setting both the X-axis drive mechanism 3 and the Y-axis drive mechanism 4 on the machine base 1, and mounting the Z-axis drive mechanism 5 on the Y-axis drive mechanism 4, etc. The key is to achieve precise movement of the wire drawing head mounting mechanism in three-dimensional space.

[0085] In other embodiments of this example, the first locking structure and the second locking structure may also adopt other forms of locking devices such as quick clamps or cam locking mechanisms, as long as they can achieve quick locking and release of the position.

[0086] This embodiment provides a rotary wire drawing machine, which is particularly suitable for the rotary wire drawing process of automotive aluminum decorative parts. It can efficiently and precisely process three-dimensional textured patterns on the surface of aluminum plates, significantly improving the decorative quality and visual effect of automotive decorative parts.
