1. Micro-arc oxidation, also known as micro-plasma oxidation, is to grow a ceramic membrane layer mainly composed of matrix metal oxides on the surface of aluminum, magnesium, titanium and their alloys through the combination of electrolyte and corresponding electrical parameters.
2. Metal wire drawing is a kind of surface treatment method which forms lines on the surface of workpiece by grinding products and plays a decorative role.
3. Blue burning is made by filling the whole carcass with colored glaze and then baking it in a blast furnace with a temperature of about 800℃. Glass is melted from sandy solid into liquid, and after cooling, it becomes gorgeous glass fixed on the carcass. At this time, the colored glaze is lower than the height of the copper wire, so it needs to be refilled, and then it is sintered four or five times continuously until the pattern is even with the cloisonne pattern.
4. Shot peening is a cold working process that bombards the surface of the workpiece with projectiles and injects residual compressive stress to improve the fatigue strength of the workpiece.
5. Sandblasting is a process of cleaning and roughening the substrate surface by the impact of high-speed sand flow, that is, compressed air is used as the power to form a high-speed jet beam, and gunning materials (copper ore, quartz sand, emery, iron sand and Hainan sand) are sprayed on the surface of the workpiece to be treated at high speed, so that the appearance or shape of the outer surface of the workpiece surface changes.
6. Etching is a technology to remove materials by chemical reaction or physical impact. Etching, also called photochemical etching, refers to removing the protective film from the area to be etched after exposure and development, and contacting with chemical solution during etching to achieve the effect of dissolving corrosion and forming concave-convex or hollow molding.
7. IMD (in-mold decoration technology), also known as paint-free technology, is an internationally popular surface decoration technology. The surface hardened transparent film, the middle printed pattern layer, the back injection layer and the middle of the ink make the product friction-resistant, prevent surface scratches, and keep the color bright for a long time.
The abbreviation of 8.8. OMD out-of-mold decoration is a decorative technology which integrates vision, touch and function promoted by IMD. It is a 3D surface decoration technology that combines printing, texture and metallization features.
9. Laser engraving, also known as laser engraving or laser marking, is a surface treatment process based on optical principles. Laser beams are used to engrave permanent marks on the surface of materials or inside transparent materials.
10. EDM is a special machining method, which uses the electric corrosion generated by pulse discharge between two electrodes immersed in working fluid to remove conductive materials. Also known as electrical discharge machining or electrical erosion machining, the English abbreviation is EDM. Tool electrodes are usually made of corrosion-resistant materials with good conductivity, high melting point and easy processing, such as copper, graphite, copper-tungsten alloy and molybdenum. In the process of machining, the tool electrode also has loss, but it is less than the erosion of the workpiece metal and even close to no loss.
1 1. Laser flower biting uses high-energy density laser to react with steel surface to form snakeskin/etched/pear blossom land or other patterns.
12. pad printing is a special printing method, that is, using a steel (or copper, thermoplastic) intaglio, using an arc pad printing head made of silicone rubber, dipping ink on the intaglio on the surface of the pad printing head, and then pressing it on the surface of the desired object to print characters, patterns, etc.
13. screen printing is to stretch silk fabric, synthetic fiber fabric or metal screen on a screen frame, and make a screen printing plate by hand carving paint film or photochemical plate making. Modern screen printing technology is to make a screen printing plate by photographic plate making with photosensitive materials (making the screen holes in the graphic part of the screen printing plate as through holes, but not blocking the screen holes in the graphic part). When printing, the ink is squeezed by the scraper and transferred to the substrate through the mesh of the graphic part to form the same graphic as the original.
14. Direct thermal printing refers to a method of coating thermal agent on paper to make it a thermal recording paper. Thermal recording paper changes the physical or chemical properties of a substance (developer) under the action of heat, thus obtaining an image.
15. The principle of thermal transfer printing is that the digital pattern is printed on a special transfer paper by a printer, and then the pattern is accurately transferred to the surface of the commodity by a special transfer machine at high temperature and high pressure to complete the printing of the commodity.
16. Lithography Because the graphic part and non-graphic part of lithography are on the same plane, in order to distinguish the graphic part or non-graphic part of printing plate with ink, based on the principle of oil-water separation, the non-graphic part of printing plate is first supplied with water by the water supply device of printing plate, thus protecting the non-graphic part of printing plate from being wetted by ink. Then, ink is supplied to the printing plate by the ink supply device of the printing section. Because the non-graphic part of the printing plate is protected by water, ink can only be supplied to the graphic part of the printing plate. Finally, the ink on the printing plate is transferred to the milk skin, and then the ink on the milk skin is transferred to the substrate by the pressure between the cots and the impression cylinder, thus completing a printing. Therefore, lithography is an indirect printing method.
17. Curved surface printing is to put the ink into an intaglio engraved with characters or patterns, then copy the characters or patterns onto the curved surface, then transfer the characters or patterns onto the surface of the molded product by using the curved surface, and finally cure the ink through heat treatment or ultraviolet irradiation.
18. Hot stamping, commonly known as "hot stamping", refers to the hot stamping of characters and patterns made of materials such as colored foil on the cover and the first or fourth back of a hardcover book, or the hot stamping of various titles or patterns of scraggy.
19. Water transfer printing is a kind of printing that hydrolyzes transfer paper/plastic film with color patterns by water pressure. The technological process includes making water transfer decal paper, soaking decal paper, pattern transfer, drying and finished product.
20. Flat screen printing, the printing die is a polyester or nylon silk screen (pattern) fixed on a square frame with a hollow pattern. The color paste can penetrate the pattern on the pattern board, and the mesh is sealed with polymer film where there is no pattern. When printing, press the pattern plate on the fabric, fill the color paste on the pattern plate, and scrape it back and forth with a scraper to make the color paste reach the surface of the fabric through the pattern.
2 1. Calendering is also called calendering. The last process of finishing heavy leather. Using the plasticity of fiber under mixed heat condition, the surface of fabric is flattened or rolled into parallel fine diagonal lines to improve the luster of fabric. After the material is fed, it is heated and melted, then shaped into a sheet or film, and then cooled and rolled up. The most commonly use calendering material is polyvinyl chloride.
