Micro-arc oxidation is a surface treatment technology that generates arc discharge on the surface of metals such as aluminum, magnesium, titanium, and their alloys through a combination of electrolytes and electrical parameters to form a ceramic film layer mainly composed of base metal oxide. During the micro-arc oxidation process, the workpiece is placed in the electrolyte as an anode. Under the action of an external electric field, micro-arc discharge is generated on the surface, resulting in instantaneous high temperature and high pressure. This causes the surface material of the material to undergo a series of physical and chemical changes such as electrical breakdown, melting, chemical reaction, solidification, diffusion, and phase change, and finally forms a ceramic film layer with excellent performance on the surface of the base material.

Metal wire drawing is a metal processing process that compresses the metal cross-sectional area by forcing the metal through a die under the action of an external force, thereby obtaining the desired cross-sectional shape and size. The wire drawing process mainly includes raw material preparation, wire drawing machinery and equipment debugging, wire drawing process control, and subsequent processing. The wire drawing process can provide different surface textures, such as straight lines, random lines, threads, corrugations, and spiral lines, which are not only decorative but also improve the texture and appearance of the product.

Black oxidize is a metal surface treatment process mainly used for steel materials. Bluing is to place steel parts in a solution containing an oxidant, such as molten salts of sodium nitrite and sodium nitrate, or in high-temperature hot air and superheated steam above 500°C. A more common practice is to heat in concentrated caustic soda with sodium nitrite. After this treatment, a layer of oxide film mainly composed of magnetic iron oxide will be formed on the metal surface, with a thickness of about 0.5 to 1.5 microns.

Shot peening is a surface treatment technology that uses high-speed steel or sand shots to impact the surface of the workpiece to improve the mechanical strength, wear resistance, fatigue resistance, and corrosion resistance of the parts. Shot peening can not only remove the oxide scale, rust, and old paint film on the surface of the workpiece but also improve the fatigue life of the parts through surface strengthening.

Etching is a manufacturing process that removes part of the material from the surface of the material by chemical or physical methods to form a specific pattern or design. The etching process can be achieved by wet etching (using chemical solutions) and dry etching (using plasma or laser). Wet etching involves immersing the material in a chemical solution, while dry etching uses plasma or laser to precisely remove part of the surface of the material.

In-Mold Decoration (IMD) is an advanced manufacturing technology that embeds decorative patterns directly into the molding process of plastic parts. The IMD process includes cutting, flat printing, ink drying and fixing, applying protective film, punching positioning holes, thermoforming, shearing the shape, and finally placing the formed sheet into the injection mold cavity to complete the injection molding.

Out-of-mold decoration (OMD) is an advanced surface treatment technology that gives products a richer and more three-dimensional appearance by decorating the workpiece outside the mold. The process flow of OMD usually includes: using pressure differential coating decoration technology; without the need for molds and injection molding machines, only the workpiece and simple fixtures can be used for rapid proofing. The diaphragm achieves three-dimensional high-stretch bonding and can achieve the effect of an inverted third edge.

Laser engraving processing is based on numerical control technology, with laser as the processing medium. The instantaneous melting and vaporization of processing materials under laser engraving irradiation can achieve the purpose of laser engraving processing through physical deformation. Laser engraving is the use of laser technology to engrave text on objects. The characters engraved by this technology have no scratches, the surface of the object remains smooth, and the handwriting will not wear out.

A special machining method that utilizes the electroerosion produced by pulse discharge between two poles immersed in theworking fluid to erode conductive materials, also known as electrical discharge machining or electroerosion machining, or EDM in English. Tool electrodes commonly use corrosion-resistant materials with good conductivity, high melting points, and easy processing, such as copper, graphite, copper-tungsten alloy, and molybdenum. During the machining process, the tool electrode also suffers loss, but it is less than the amount of workpiece metal removal, and is even close to no loss.

Laser bite is an important surface treatment technology in industrial manufacturing. It refers to a small area or point in the laser cutting process where the laser beam interacts with the material, causing the material to be removed.

Pad printing is one of the special printing methods. It can print text, graphics, and images on the surface of irregularly shaped objects and has now become an important special printing. For example, the text and patterns on the surface of mobile phones are printed using this method.

Screen printing refers to the use of screen as a substrate and the use of photosensitive plate making methods to produce screen printing plates with graphics and text. Screen printing consists of five main elements: screen printing plate, scraper, ink, printing table, and substrate. The basic principle of printing is that the mesh holes in the graphic and textual parts of the screen printing plate can pass through ink, while the mesh holes in the non graphic and textual parts cannot pass through ink. When printing, ink is poured into one end of the screen printing plate, and a scraper is used to apply a certain pressure to the ink area on the screen printing plate. At the same time, the ink moves at a constant speed towards the other end of the screen printing plate. During the movement, the scraper presses the ink from the mesh of the graphic and text parts onto the substrate.

Direct thermal printing is a technology that uses thermal paper and print heads for printing. Its working principle is to heat the thermal paper through the semiconductor heating element on the print head, thereby generating a chemical reaction on the paper to form the desired pattern or text.

The transfer printing process uses a heat transfer machine to transfer the exquisite patterns on the transfer film onto the surface of the product in one go (heating and pressure). After forming, the ink layer integrates with the surface of the product, creating a realistic and beautiful image, greatly improving the product\\\'s grade. However, due to the high technological content of this process, many materials need to be imported.

Photolithography technology refers to the technique of transferring patterns from a mask to a substrate using photoresist under the influence of light. The main process is as follows: firstly, ultraviolet light is irradiated through a mask onto the surface of the substrate with a layer of photoresist film attached, causing a chemical reaction in the photoresist in the exposed area; Then, by using development technology to dissolve and remove the photoresist in the exposed or unexposed areas (the former is called positive photoresist, and the latter is called negative photoresist), the pattern on the mask is replicated onto the photoresist film; Finally, the pattern is transferred onto the substrate using etching technology.

Curved printing refers to the printing method of printing on substrates with curved shapes. This printing method is suitable for various curved substrates, such as cylindrical or conical metal, plastic, glass containers, or shaped objects

Hot stamping forming technology utilizes the principle of metal thermoplastic forming to achieve quenching heat treatment of sheet metal while forming, improving the formability of materials and greatly expanding the application range of high-strength and ultra high strength steel in automotive parts.

Water transfer printing technology uses water as a medium to transfer images and text onto the surface of a substrate through an intermediate carrier (special paper or plastic film), thereby achieving printing function. There are two types of water transfer printing technology, one is water label transfer printing technology, and the other is water coating transfer printing technology. The former mainly completes the transfer printing of text and photographic patterns, while the latter tends to perform complete transfer printing on the entire surface of the product.

Flat screen printing is a process of using a nylon mesh as a plate material. The mesh is stretched onto a metal or wooden rectangular frame, and the pattern is carved onto the mesh. The mesh is hollowed out in areas with patterns. During the printing process, the ink transfers the pattern onto the textile through the mesh.
