I didn't expect these surface texture decorations to be achieved by the printing process
1. IMR process
IMR (in-mold transfer) This process is to print the pattern on the film, through the film feeding machine to fit the diaphragm and the plastic cavity for extrusion, after extrusion, the ink layer with the pattern is separated from the film, the ink layer is left on the plastic part and the surface of the plastic part with a decorative pattern is obtained, there is no transparent protective film on the surface of the final product, and the film is just a carrier in the production process. IMR's products are not easy to deform, the product edge is completely coated, the edge adhesion is strong, it is very easy to change the roll of IMR transfer foil, the process is simple, so the defective rate can be controlled within a few points, the process is simple, so the personnel demand can be reduced to a minimum, the pattern alignment is perfect, the hardness can reach 2H, the degree of automation during production is high and the cost of mass production is low.
2. UV transfer process
UV transfer process, also known as UV infusion process or UV coating process, it uses the characteristics of UV transfer glue and metal non-stickiness to transfer the effect of various mobile phone ultra-thin keys to PET or PC sheet through UV transfer process (mobile phone keys are also transferred to copper or aluminum sheets), so as to make, including CD pattern, brushed, matte, glossy texture and other effects of ultra-thin keys and key-type, such as number keys, red and green phones, blind spots and other effects of mobile phone ultra-thin buttons, lenses, navigation keys and product logos; At the same time, this process is widely used in PET, PMMA, PC and other sheets to make the effect of vertical wire drawing on the front. It is mainly used in the 3C industry, mobile phone windows, mobile phone buttons, mobile phone LOGO, decorative pieces and other fields.
3. Water transfer printing process
Water transfer printing technology is a kind of printing that uses water pressure to hydrolyze the transfer paper/plastic film with color patterns. With the improvement of people's requirements for product packaging and decoration, the use of water transfer printing is becoming more and more extensive. The principle of indirect printing and the perfect printing effect solve many problems of product surface decoration. There are two types of water transfer technology, one is water mark transfer technology, and the other is water coating transfer technology. The former mainly completes the transfer of text and photo patterns, while the latter tends to complete the transfer of the entire surface of the product. Water transfer printing technology is mainly used in automotive interiors such as automobile dashboards and control panels, 3C electronic products, daily household appliances, building materials, etc.
4. Silk screen printing
In the eyes of designers, silk screen printing is simple and cheap, and the effect is not bad, commonly known as cost-effective! It is printed by attaching a template with an image or pattern to a silk screen, and is suitable for products with a flat surface, a single curved surface or a small drop in the curved surface. Usually the wire mesh is made of nylon, polyester, silk or metal mesh. When the substrate is placed directly under the screen with the stencil, the screen printing ink or paint is squeezed by the squeegee through the mesh in the middle of the screen and printed onto the substrate (there are two types of squeegee blades: manual and automatic). The stencil on the screen seals a part of the mesh hole so that the pigment cannot pass through the screen, but only the image part, so that only the image part is imprinted on the substrate.
5. Biting process
Bite flower is to create a variety of patterns on the surface of metal products through chemical osmosis, such as stripes, images, wood grains, leather grains, and satin, etc., including sandblasting procedures, which are to spray glass sand directly onto the surface of metal products. It is mainly used in the automotive industry, electronic and electrical industry, daily necessities industry, plastic and plastic industry, toy industry, leather industry, etc.
6. Hot stamping
Hot stamping is commonly known as "hot stamping", and the essence of hot stamping is transfer printing, which is the process of transferring the pattern on the hot stamping paper to the substrate through the action of heat and pressure. The pressure of the mold produces depressions, and the printed words or patterns are not easy to blur, so that the patterns, logos, texts or pictures can be firmly glued to the surface of the product. Hot stamping and foil are the two key components of the hot stamping process, hot stamping is generally composed of magnesium, brass and steel, and some will use silicone rubber on the surface of the metal hot stamping for not very flat surfaces. Hot stamping foil mainly includes carrier, release layer, protective layer and decorative layer.
7. Laser engraving (laser engraving)
Based on numerical control technology, laser is the processing medium. The instantaneous melting and vaporization of metal materials under laser irradiation are physically denatured, so as to achieve the purpose of processing. Using laser engraving technology with a laser enggraver, vectorized graphics can be easily "printed" onto the substrate being processed.
8. Metal etching
Also known as photochemical etching. After exposure plate making and development, the protective film on the area to be etched is removed, and the metal is exposed to the chemical solution during etching to achieve the effect of dissolving corrosion and forming the effect of concave and convex or hollow molding. For general consumer products, the patterns or text logos on aluminum plates are often made by etching. In addition, etching is often used to make various metal horn meshes.
9. Embossing
Metal embossing is embossed on the metal plate by mechanical equipment, so that the plate surface appears concave and convex pattern. When the embossed metal sheet is rolled, it is rolled with a patterned work roll, and the work roll is usually processed with an erosion liquid, and the depth of the concave and convex on the plate varies depending on the pattern, and the minimum can reach 0.02-0.03mm. After rolling by the continuous rotation of the work roller, the pattern is repeated periodically, and the length direction of the embossed plate is basically not limited. At present, metal embossed plates are suitable for decorating elevator cars, subway cars, various cabins, architectural decoration, metal curtain walls and other industries. It has the advantages of durable, durable, wear-resistant, visually beautiful, easy to clean, maintenance-free, anti-resistance, anti-compression, anti-scratch and no finger prints.
10. Metal hot stamping
It refers to the use of a special metal hot stamping plate to transfer the hot stamping foil to the surface of the substrate by heating and pressurizing. On the other hand, hot stamping on metal substrates requires the adhesion of hot stamping film after passing a proprietary metal hot stamping film or spraying on the surface of the substrate. Due to the diversity of hot stamping foils, the metal substrate can also be processed quickly, diversely, and more environmentally friendly to achieve our original design intention.
