Description

Technical Field

[0001] The invention relates to the technical field of injection molding nameplate manufacturing, in particular to a method for manufacturing an injection molding nameplate with jade simulation effect. Background Art

[0002] Jade is beloved for its textured, light-sensitive texture. However, it's difficult to use expensive, real jade for injection-molded nameplates. Currently, the only way to simulate jade is by adding green toner to transparent plastic parts. This approach lacks the natural luster and dynamics of jade, hindering the visual expression of jade's texture and sheen. Furthermore, the resulting finished product exhibits a varying appearance, making it difficult to commercialize on a mass scale. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a method for manufacturing an injection molded nameplate with a simulated jade effect, which can obtain an injection molded nameplate with a jade simulation effect and a uniform visual appearance.

[0004] According to an embodiment of the present invention, a method for producing an injection-molded nameplate with a simulated jade effect comprises the following steps: step 1, selecting jade material, designing a simulated jade texture pattern, and producing a nickel plate with the simulated jade texture pattern; step 2, preparing a PET film, forming a release layer on the front side of the PET film, forming a molded layer on the front side of the release layer, and then sending the nickel plate to a mold press and covering it on the plate roller of the mold press, and transferring and printing the jade texture pattern on the molded layer; step 3, plating a zinc sulfide dielectric layer on the front side of the molded layer; step 4, preparing a transparent injection-molded part, coating a thermal transfer adhesive on the front side of the zinc sulfide dielectric layer to form a transparent back adhesive layer, and pasting and pressing the back adhesive layer on the back side of the injection-molded part; step 5, tearing off the PET film and the release layer from the back side of the molded layer, and silk-screening an ink layer on the back side of the molded layer to obtain a finished injection-molded nameplate.

[0005] The invention has at least the following beneficial effects: the manufacturing method designs a simulated jade texture pattern, transfers and prints it on the molded layer, and plates a transparent zinc sulfide medium layer to increase the reflective brightness and act as a barrier adhesive layer, and then sticks it on the back of the injection-molded part, wherein the PET film serves as a carrier of the molded layer and is torn off after being stuck to the injection-molded part, and finally a silk-screen ink layer is printed on the back of the molded layer, and the ink layer can play a role of protection and background color setting. The obtained injection-molded nameplate presents a jade simulation effect, has the gloss and agility of jade, and shows the visual changes of jade texture layering and gloss flow, and the obtained appearance is visually unified, can be industrially mass-produced, and has flexible and changeable application scenarios, which can well enhance the visual effect of product packaging and meet the shelf effect required by merchants.

[0006] According to some embodiments of the present invention, step one specifically includes: selecting jade material, designing a photolithography file simulating a jade texture pattern, converting the photolithography file into a dot matrix file recognizable by a platinum relief lithography machine; sending the dot matrix file to the platinum relief lithography machine, the platinum relief lithography machine interprets the pattern parameters of the dot matrix file and transmits them to a laser, and the laser laser etches the pattern on a photoresist plate; developing the etched photoresist plate with a developer to produce an image to become a photoresist master; and sending the photoresist master to an electroforming tank to electroform it into a nickel plate having the simulated jade texture pattern.

[0008] According to some embodiments of the present invention, in step 2, resin is coated on the front surface of the release layer and cured to form a molded layer.

[0009] According to some embodiments of the present invention, the thickness of the molded layer is 1.5-2 μm.

[0010] According to some embodiments of the present invention, the ink layer is black.

[0011] According to some embodiments of the present invention, the ink layer has a thickness of 6 to 12 μm.

[0021] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0022] Reference Figures 1 to 2 The present invention discloses a method for manufacturing an injection molded nameplate with a simulated jade effect, comprising the following steps:

[0023] Step 1: Select jade material, design a simulated jade texture pattern, and make a nickel plate with the simulated jade texture pattern;

[0024] Step 2: Prepare a PET film 1, form a release layer 2 on the front of the PET film 1, form a mold layer 3 on the front of the release layer 2, and then send the nickel plate to the molding machine and cover it on the plate roller of the molding machine, and transfer the jade texture pattern onto the mold layer 3;

[0025] Step 3: Plating a zinc sulfide dielectric layer 4 on the front surface of the molded layer 3;

[0026] Step 4: Prepare a transparent injection molded part 6, apply thermal transfer adhesive on the front of the zinc sulfide dielectric layer to form a transparent adhesive layer 5, and adhere and press the adhesive layer 5 to the back of the injection molded part 6;

[0027] Step 5: Tear off the PET film 1 and the release layer 2 from the back of the molded layer 3, and screen print the ink layer 7 on the back of the molded layer 3 to obtain the finished injection molded nameplate.

[0028] This production method designs a simulated jade texture pattern, transfers it onto the molded layer 3, and plates a transparent zinc sulfide dielectric layer 4. The zinc sulfide dielectric layer 4 can increase the reflective brightness and act as a barrier to the adhesive layer 5. It is then pasted on the back of the injection molded part 6. Finally, an ink layer 7 is silk-screened on the back of the molded layer 3. The ink layer 7 can play a role in protection and background color setting.

[0029] Among them, the PET film 1 is used as a carrier of the molded layer 3, which can be supported and attached to the molded layer 3 through the release layer 2. Figure 1 After the structure shown is adhered to the back of the injection molded part 6 , the PET film 1 and the release layer 2 can be torn off.

[0030] It is understandable that, according to the needs of the injection molded nameplate, the back of the injection molded part 6 can be printed with product graphic information in advance, or the product graphic information can be transferred through a hot stamping process; in step four, the back adhesive layer 5 is formed by thermal transfer adhesive, and needs to be pasted and pressed on the back of the injection molded part 6 by heating.

[0031] The injection molded nameplate obtained by this production method presents a jade simulation effect, has the gloss and agility of jade, and shows the visual changes of jade texture layering and gloss flow. Since the jade texture pattern can be transferred and printed on the molded layer 3 in batches, the final injection molded nameplate has a uniform visual appearance, can be industrially mass-produced, and has flexible and changeable application scenarios. It can greatly enhance the visual effect of product packaging and meet the shelf effect required by merchants.

[0032] In some embodiments of the present invention, step one specifically includes:

[0033] Select jade material, design a photolithography file that simulates the jade texture pattern, and convert the photolithography file into a dot matrix file that can be recognized by the platinum relief lithography machine;

[0034] The dot pattern file is sent to a platinum relief lithography machine, which interprets the pattern parameters of the dot pattern file and transmits them to the laser, which then etches the pattern onto the photoresist plate.

[0035] The etched photoresist is developed with a developer to produce an image to form a photoresist master;

[0036] The photolithography master is sent to the electroforming tank to be electroformed into a nickel plate with a pattern simulating jade texture.

[0037] Through the above series of conversion steps, a nickel plate with a pattern simulating jade texture can be obtained, which can then be conveniently coated on the plate roller of the molding machine.

[0038] Reference Figure 1 In some embodiments, in step 2, silicone oil is applied to the front surface of the PET film 1 to form a release layer 2, and resin is applied to the front surface of the release layer 2 and cured to form a molded layer 3. The release layer 2 formed by silicone oil is convenient for adhering to the molded layer 3 formed by the resin and has good peelability, making it easy to tear off from the molded layer 3. The resin has a tendency to flow under the action of external force, making it very suitable for the molded layer 3 that carries the imprint.

[0039] Reference Figure 2In some embodiments, the thickness of the molded layer 3 can be specifically 1.5 to 2 μm, and the ink layer 7 is black. Alternatively, an ink layer 7 of another color can be screen-printed first, and then a black ink layer 7 can be screen-printed. The thickness of the ink layer 7 can be specifically 6 to 12 μm, and the thickness of the adhesive layer 5 can be specifically 1 to 1.5 μm.

[0040] In some embodiments, product graphic information is printed on the back of the injection molded part 6 , and the product graphic information includes but is not limited to product marks, texts, trademarks and patterns.

[0041] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] Of course, the present invention is not limited to the above-mentioned embodiments.
