Description

Technical Field

[0001] This invention belongs to the field of sheet metal processing technology, and specifically relates to a manufacturing method for integrated artistic edge banding. Background Technology

[0002] In the field of board processing, especially in furniture manufacturing and interior decoration, edge banding is a key process aimed at improving aesthetics, protecting the substrate, preventing moisture intrusion, and blocking the release of internal substances. Currently, the mainstream edge banding technology in the market mainly relies on the physical bonding mode of "edge banding strip + adhesive", specifically including EVA (ethylene-vinyl acetate copolymer) hot melt adhesive edge banding, PUR (moisture-curing reactive polyurethane) hot melt adhesive edge banding, and laser edge banding. EVA edge banding is a mature and low-cost process, while PUR edge banding has been optimized in terms of bonding strength, temperature resistance, and adhesive usage. Laser edge banding achieves bonding by activating the adhesive on the back of the edge banding strip with a laser, in order to obtain a better sealing effect.

[0003] However, these existing technologies are essentially "secondary bonding" processes. There is a physical interface between the edge banding strip and the substrate, making it difficult to completely eliminate microscopic gaps and visible glue lines. This not only affects the aesthetics but also provides a channel for moisture and contaminants to penetrate, easily leading to delamination and edge lifting with long-term use. Secondly, traditional processes are highly dependent on adhesives, posing environmental risks (such as VOC release), easy aging of adhesives, and uneven weather resistance. In addition, while high-end technologies such as laser edge banding improve the appearance to some extent, they face challenges such as huge equipment investment, the need for specialized supporting materials, complex processes, and the need to verify product stability, making them difficult to popularize. Summary of the Invention

[0004] The purpose of this invention is to provide a manufacturing method for integrated artistic edge banding to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A method for manufacturing an integrated artistic edge banding includes the following steps:

[0007] S1. Board Pre-treatment: Provide the board to be edge-banded and pre-treat its edge areas;

[0008] S2. Resin Preparation: Provide flowable curable resin material;

[0009] S3, Resin Filling: The flowable cured resin material is filled into the edge area of ​​the plate;

[0010] S4. Curing and molding: Curing the resin material filled in the edge area of ​​the board to form an edge sealing layer integrated with the board;

[0011] S5. Post-processing: Surface treatment and / or cutting of the cured integrated edge banding board.

[0012] Preferably, the flowable curable resin material is ABS resin.

[0013] Preferably, in step S1, the preprocessing includes using a CNC engraving machine to engrave a predetermined shape or structure in the edge area of ​​the plate.

[0014] Preferably, in step S3, the resin filling is achieved through a casting pipeline system, which includes a storage tank, a heating device, and a flow control device.

[0015] Preferably, in step S4, the curing includes flattening and heating curing using a hot press.

[0016] Preferably, step S5 includes using a thickness sander to smooth the surface of the cured board.

[0017] Preferably, step S5 includes using a precision cutting machine to cut the integrated edge-banded board into a predetermined size.

[0018] Preferably, the method employs a whole-board carving and forming process, completing the edge sealing of the entire board in a single processing step.

[0019] Preferably, the method employs a small-plate mold forming process, specifically including:

[0020] Prepare corresponding edge banding molds according to the specifications of the board material;

[0021] The flowable, curable resin material is filled into the mold and surrounds the edge of the sheet material;

[0022] After the resin has cured in the mold, it is demolded to obtain an integrated edge-sealing board.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] (1) By adopting an innovative process that directly bonds the flowable curing resin to the edge of the board and integrally forms it, the inherent defects of the traditional "edge banding strip + glue" mode, such as physical gaps, visible glue lines and obvious joints, are solved from the structure. The resulting integrated edge banding layer is firmly bonded to the substrate and achieves seamless connection. This not only greatly improves the aesthetics and integrity of the edge banding area, but also achieves complete coverage and sealing of the board cross section. This sealing structure can effectively block the escape path of the material inside the board. At the same time, the edge banding layer itself has excellent comprehensive properties such as resistance to yellowing, resistance to temperature changes, wear resistance and high hardness, thereby significantly extending the service life of the product and improving the user experience.

[0025] (2) Abandoning the combination of traditional adhesives and separate edge banding strips, environmentally friendly resin materials are used to reduce the potential release of volatile organic compounds (VOCs) from the source, which is more in line with the requirements of green and environmentally friendly production. At the same time, this method has a wide range of process adaptability. It can achieve efficient mass production of standardized boards through whole board carving and molding, and can also flexibly meet the edge banding needs of small-sized, irregular or complex artistic boards through mold forming. Attached Figure Description

[0026] Figure 1 This is a flowchart of the present invention. Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1:

[0029] Please see Figure 1 As shown, a method for manufacturing an integrated artistic edge banding includes:

[0030] S1. Pre-treatment of sheet materials:

[0031] Provide the substrate material to be edge-banded (such as particleboard, MDF, plywood, etc.). Fix the material onto the worktable of the CNC engraving machine. According to the preset edge-banding design (such as right angles, rounded corners, embossed patterns, etc.), the CNC system controls the engraving cutter to precisely mill and engrave the edge area of ​​the material, forming grooves or shaped surfaces of the predetermined shape and depth. After engraving, use a high-pressure air gun or dust collector to thoroughly clean the wood chips and dust generated during engraving, ensuring that the edge area is clean and free of residue, which is conducive to the subsequent resin bonding.

[0032] S2. Resin Preparation:

[0033] Prepare ABS resin as the edge sealing material. Add granular or powdered ABS resin raw material to a dedicated resin storage tank. Heat the resin to its melting temperature range (e.g., 180℃-220℃) using the tank's heating system (such as an electric heating mantle or oil bath heating), and continuously stir until it reaches a uniform, stable, and well-flowing molten state. Both the heating and heat preservation processes are carried out in a closed system to prevent resin oxidation or degradation.

[0034] S3, Resin Filler:

[0035] Molten ABS resin is delivered to the sculpted edge area of ​​the sheet material through an insulated pouring system. This system includes an insulated pipe connected to a storage tank, a metering pump or screw extruder (as a flow control device), and a movable pouring head. The control system precisely controls the resin output, pouring speed (e.g., 100-500 mm / s), and pouring path based on the length of the sheet material edge and the complexity of the design. This ensures that the molten resin completely and evenly fills all the grooves and depressions formed during sculpting, leaving a slight margin above the sheet surface.

[0036] S4, Curing and Molding:

[0037] After the resin filling is completed, the board is immediately transferred to the hot pressing station. A flatbed hot press is used to flatten and heat the resin-filled edge area under certain temperature (e.g., 80℃-120℃), pressure (e.g., 0.5-2.0 MPa), and time (e.g., 60-180 seconds). The hot pressing process squeezes out excess resin and accelerates the curing and cross-linking reaction of the resin, so that it forms a strong chemical and physical bond with the board matrix. After cooling, a high-strength, high-gloss edge sealing layer is formed that is integrated with the board.

[0038] S5. Post-processing:

[0039] After curing, the boards are first surface-treated using a thickness sander. The sander uses fine-grit sanding belts (e.g., 240 grit or higher) to finely sand the resin edge banding layer and the transition area between it and the board surface, removing any minor unevenness that may have occurred during the flattening process, ensuring that the entire board has a uniform thickness and a smooth, flat surface. Subsequently, according to the final product size requirements, a precision panel saw (such as a CNC panel saw) is used to cut the board with integrated edge banding into the required dimensions. Finally, the edges and corners of the cut boards are lightly chamfered or polished, cleaned, and then packaged and stored.

[0040] As can be seen from the above, the "whole board carving and forming process" provided in this embodiment realizes one-time, automated, and integrated edge banding processing of the entire board edge, with high production efficiency. It is especially suitable for standardized and mass production. The edge banding boards produced by this process are seamless, glue-free, aesthetically pleasing, and have excellent edge banding layer performance.

[0041] Specifically, regarding the key parameters in the above steps, for example, for a 18mm thick MDF, the engraving depth can be set to 2-3mm and the width to 5-10mm; the preferred ABS resin melting temperature is 190℃-210℃; the preferred hot-press curing temperature is 100℃, the pressure is 1.0MPa, and the time is 120 seconds.

[0042] As can be seen from the above, by controlling the pretreatment shape, resin melting state, filling amount and curing conditions, this method can stably produce high-quality integrated artistic edge banding panels.

[0043] Example 2:

[0044] This embodiment provides another method for manufacturing integrated artistic edge banding, specifically employing a "small board mold forming process." This method is particularly suitable for edge banding of small-sized, multi-specification, complex-shaped, or high-surface-precision boards, and features flexibility, efficiency, and high repeatability. The specific steps are as follows:

[0045] S1. Mold Design and Sheet Material Preparation:

[0046] First, based on the precise dimensions and edge banding design (such as complex carvings, Roman columns, and irregular curved surfaces) of the target product (e.g., furniture door panels, decorative moldings, tabletop edges), a dedicated edge banding mold is designed and manufactured. The mold can be made of metal (e.g., aluminum alloy, steel) or high-temperature resistant silicone, and its cavity shape perfectly matches the final contour of the area to be edge-banded on the board, including mechanisms for positioning and clamping the board. Simultaneously, the edges of the substrate small board to be edge-banded (e.g., pre-cut furniture components) undergo routine cleaning and activation treatment (e.g., wiping with alcohol or plasma treatment) to enhance resin adhesion.

[0047] S2. Resin Preparation and Optional Materials:

[0048] In this embodiment, the flowable curable resin material is not limited to ABS resin; other thermosetting or photocurable resins, such as epoxy resin or polyurethane (PU) resin, can also be used. Taking two-component epoxy resin as an example, the resin component and the curing agent component are placed in two separate storage tanks at a predetermined ratio (100:30), and precisely delivered to a static mixer or dynamic stirring head via a metering pump. The mixture is then online and uniformly mixed at room temperature or under moderate heating (40℃-60℃) to form a flowable mixed resin slurry with suitable viscosity. This step allows for rapid proportioning and immediate use, preventing premature resin curing.

[0049] S3. In-mold filling and venting:

[0050] Precisely install and fix the pre-treated small board inside the cavity of the edge-sealing mold, ensuring that the desired edge-sealing layer cavity is formed between the edge of the board and the mold cavity wall. Close the mold and inject the mixed resin slurry into the mold cavity under low pressure (0.2-0.8 MPa) through the pre-set injection port on the mold. The gating system can be designed with multi-point injection to ensure that the edges of large or complex shapes are completely filled. The mold is equipped with venting grooves or venting pins to expel air from the cavity during the resin filling process, preventing defects such as air bubbles and insufficient glue.

[0051] S4, In-situ curing:

[0052] After the resin fills the mold cavity, it is cured according to the curing characteristics of the selected resin. For epoxy resin, the mold temperature can be maintained at 70℃-90℃ through the heating pipes built into the mold (temperature controlled by an oil temperature controller) to promote complete curing of the resin within 15-30 minutes. For UV-curing resin, after filling, it is rapidly cured by irradiating it with ultraviolet light of a specific wavelength for a certain period of time (60-120 seconds) through a transparent window on the mold or by using a transparent mold material. The curing process is carried out under the constraint of the mold, which can ensure that the dimensional accuracy and surface finish of the sealing layer reach the level of the mold cavity.

[0053] S5. Demolding and finishing:

[0054] After the resin has fully cured, open the mold and remove the molded part with integrated edge sealing. Due to the high precision of the mold, the edge sealing layer after demolding usually has a very good surface quality and does not require extensive sanding; only a few parting line marks may need to be slightly treated with fine sandpaper or a polishing wheel. Subsequently, the non-edge sealing surfaces of the board can be cleaned or protected as needed, and finally inspected and packaged.

[0055] Example 3:

[0056] This embodiment provides an integrated artistic edge banding manufacturing method based on paste-like wood putty repair agent. This method is suitable for process scenarios that do not require high-temperature melting and hot-press curing equipment, and is especially suitable for small and medium-sized production enterprises or occasions where equipment investment is limited.

[0057] Using paste-like filling material, no heating or melting is required. The curing process can be completed at room temperature or low temperature. The process is simple, energy-efficient, and more environmentally friendly.

[0058] The specific steps are as follows:

[0059] S1. Board Pre-treatment and Carving: Provide the board to be edge-banded (such as particleboard, MDF, solid wood composite board, etc.) and fix it on the CNC carving machine worktable; according to the edge-banding design, CNC carve the edge area of ​​the board to form grooves or decorative textures of predetermined depth and width; after carving, use a high-pressure air gun or dust collection equipment to thoroughly clean the edge area to ensure that there is no dust or wood chips left.

[0060] S2. Putty preparation:

[0061] When using paste-like wood putty for repair as a filling material, one of the following two types can be selected:

[0062] Water-based wood putty: The main components are calcium carbonate, water-based resin and additives. It is environmentally friendly and odorless. After curing, it has moderate hardness and is easy to sand.

[0063] Two-component epoxy resin filler (AB epoxy resin): After curing, it has high strength, wear resistance and strong adhesion, and is suitable for occasions with high requirements for the performance of the sealing layer.

[0064] If using a two-component material, weigh it precisely according to the ratio and mix it evenly. Let it stand to defoam before use.

[0065] S3. Vacuum translation and filling: The carved board is smoothly transferred to a special filling worktable through a vacuum adsorption system. The worktable is equipped with positioning clamps to ensure the accurate position of the board. Using a scraper, glue gun or automatic glue dispensing equipment, paste putty is evenly filled into the carved area at the edge of the board to ensure that the filling is dense and free of air bubbles, and slightly higher than the surface of the board for subsequent finishing.

[0066] S4, Curing and Molding:

[0067] After the filling and flushing are completed, allow the putty to cure according to the selected type:

[0068] Water-based wood putty: Cures at room temperature, or accelerates curing at 40℃–60℃ using low-temperature drying equipment (such as infrared lamps or hot air circulation boxes), taking approximately 30–90 minutes.

[0069] Epoxy resin filler: Cured at room temperature or low temperature (50℃–70℃) for approximately 60–180 minutes.

[0070] No pressure is required during the curing process; a smooth surface is formed by the material's own leveling and shrinkage properties.

[0071] S5. Post-treatment: After complete curing, use a thickness sander or hand sanding tools to smooth the edge banding layer, removing excess material and ensuring a smooth transition between the edge banding layer and the board surface. Then, use a precision panel cutter to cut the board to the required size, and lightly chamfer or polish the edges and corners. After cleaning, the finished product is obtained.

[0072] Example 4:

[0073] This embodiment provides an integrated artistic edge banding manufacturing method that adds a flat-laying process after fixed-thickness sanding. It is suitable for application scenarios that require further surface decoration or functional veneer after edge banding, such as furniture door panels and wall decoration panels.

[0074] This method enhances the overall visual effect and surface performance of the board by using a veneer process while ensuring integrated edge banding.

[0075] The specific steps are as follows:

[0076] S1. Pre-treatment and carving of the board material: Select the base material (such as MDF, particleboard, etc.), fix it on the CNC engraving machine, carve the edge sealing shape in the edge area according to the design, and clean the dust.

[0077] S2. Resin Filling: Flowable curable resin material (such as epoxy resin or polyurethane resin) is used to fill the engraved area through a gating system, ensuring fullness and no air bubbles.

[0078] S3. Curing and Thickness Sanding: After the resin has cured at room temperature or under heating conditions, use a thickness sander to sand the edge sealing layer and the board surface to ensure a smooth surface and uniform thickness.

[0079] S4. Flat Laying: Apply an environmentally friendly adhesive (such as PUR hot melt adhesive or water-based adhesive) evenly to the sanded board surface. Lay the decorative surface material (such as wood veneer, decorative paper, PVC film, thin high-density board, etc.) flat onto the board surface. Use a cold press or hot press to press under a certain pressure (0.5-1.5 MPa), the time depending on the type of adhesive (60-300 seconds), to ensure a firm bond and no air bubbles.

[0080] S5. Cutting and Sanding: After lamination, use a precision cutting machine to cut the board to the required size. Sand the cut edges to ensure they are smooth and burr-free.

[0081] S6. Edge and corner coating: Spray or roll a transparent protective varnish (such as UV varnish or water-based varnish) onto the edge sealing area and corners of the veneer to enhance the wear resistance, moisture resistance, and aesthetics of the edges and corners. Multiple thin coats can be applied, with each coat lightly sanded after drying before applying the next coat, and finally cured.

[0082] S7. Packaging finished products: After passing inspection, clean the surface and package the finished products for storage.

[0083] Example 5:

[0084] This embodiment provides an integrated artistic edge banding manufacturing method that adds an overall fine finishing and topcoat coating process after the board is opened and sanded. It is suitable for scenarios with high requirements for surface gloss, feel and durability, such as high-end custom furniture, exhibition display boards, etc.

[0085] This method achieves visual and performance uniformity between the edge banding and the panel surface through overall coating.

[0086] The specific steps are as follows:

[0087] S1. Pre-treatment and carving of the board: Same as in Example 4, CNC carving and cleaning are performed.

[0088] S2. Resin filling and curing: Use high-level epoxy resin or UV resin to fill the edge area, and form a seamless edge sealing layer after curing.

[0089] S3. Fixed Thickness Sanding: Fine sanding is performed on the cured board to ensure a natural transition between the edge banding and the board surface, and an overall smooth surface.

[0090] S4. Flat surface application (optional): If necessary, decorative surface material can be applied after sanding, with the process the same as in Example 4.

[0091] S5. Cutting and Grinding: Cut the board to the target size and chamfer, round, or polish all edges and corners.

[0092] S6. Overall Topcoat Coating: Multiple layers of coating are applied to the entire panel (including the edge banding area and the panel surface) using spraying equipment.

[0093] Primer coating: enhances adhesion and fills tiny pores;

[0094] Intermediate coating: Improves smoothness and thickness;

[0095] Topcoat coating: Provides final gloss, feel, and abrasion resistance.

[0096] Each coating layer is dried or UV cured, and lightly sanded as needed.

[0097] S7. Packaging the finished product: After the coating has fully cured, inspect, clean, and package it.
