Surface treatment(Metal)
Surface treatment is through the physical or chemical method in the material surface to form a layer with some or more special properties of the surface. Through the surface treatment can enhance the product appearance, texture, function and other aspects of the performance.
 
Appearance: color, pattern, logo, gloss lines (3D, 2D);
Texture: feel, roughness, life (quality), streamlined and so on;

Function: hardening, anti-fingerprint, anti-scratch;

 
Anodizing:the main material is AL, Using electrochemical principles, a layer of A1203 (alumina) film was formed on the surface of aluminum and aluminum alloy, which has some special features such as protection, decorative, insulation, wear resistance and so on.



ED-Electrophoresis deposition: for stainless steel, aluminum and so on, it can make the product presents a variety of colors, and maintain the metallic luster, while enhancing the surface properties, with good corrosion resistance.



MAO : The process of applying a high voltage to the ceramic surface layer in an electrolyte solution(typically a weakly alkaline solution) is the result of a synergistic effect of physical discharge and electrochemical oxidation.



 
PVD:It is an industrial manufacturing process, is a technology that the main use of physical processes to deposit thin film.



Electroplating:Is a technique in which a metal film is adhered to the surface of a metal by electrolysis to there by prevent corrosion, improve abrasion resistance, electrical conductivity, reflect ability and aesthetic appearance.



Powder coating:Is the use of powder coating equipment (electrostatic spray machine) to spray the powder coating to the surface of the workpiece, under static electricity, the powder will be uniformly adsorbed on the surface of the workpiece to form a powder coating; powder coating through the high temperature baking flow Flattened into a final coating with different effects (different effects of powder coatings)



Wire Drawing:it is through the grinding product in the workpiece surface to form a line pattern, play a decorative effect of a surface treatment means. According to the different lines after drawing can be divided into: straight wire drawing, chaos drawing, ripple, spin pattern.



Sandblasting:is using compressed air as the power, to form a high-speed jet to high speed injection beam will need to deal with the workpiece surface, make the appearance on the surface of the work piece surface appearance or shape changes, get a different roughness and cleanliness of a process.



Polishing:The surface modification of a work piece is modified with a flexible polishing tool and abrasive particles or other polishing medium. The surface modification of a work piece by means of a flexible polishing tool and abrasive particles or other polishing medium. For different polishing processes: coarse polishing (basic polishing process), medium polishing (finishing process) and accurate polishing (glazing polishing process), the proper polishing wheel can be used to achieve the best polishing effect, while improving the polishing efficiency.



Etching: Usually refers to the etching called photochemical etching, the exposure plate, after developing the protective film etching area will be removed, exposure to chemical etching solution, to dissolve corrosion, forming a concave convex or hollow vowin.cn/en/News/news1251.html' target='_blank'>vowin.cn/' target='_blank'>molding effect.


Baking finish:In the grinding to a certain degree of roughness of the substrate (usually high-density

sheet), spray a number of layers of paint and high temperature baking stereotypes.







 
Electroplating:the metal surface is obtained by high yield and low cost.Similar to PVD, PVD is the
physical principle, electroplating is chemical plating, mainly divided into vacuum electroplating and water plating.



Plastic parts printing : A printed process that prints the desired pattern on the surface of a plastic piece by means of printing, screen printing, transfer, and the like.


Pad printing :is an indirect veneer printing technique in which the pattern is first etched on a printed plate, the etched plate is coated with ink, and then the majority of the ink is transferred to the object being printed by the silicone head on.


Screen printing :is one of the main printing methods in stencil printing: the plates are reticulated and the ink on the plates is printed on the substrate from the perforations of the plates after the squeegee. Usually the screen is made of nylon, polyester, silk or metal mesh.


Transfer:water transfer, thermal transfer


Water transfer: is the use of water pressure will be with a color pattern transfer paper / plastic film for a polymer hydrolysis of a printing.


Thermal transfer: is a pattern or pattern printed on the heat-resistant adhesive tape, by heating, pressure, the ink layer pattern printed on the finished product on a technology.



Laser engraving: also known as laser engraving or laser marking, is a kind of optical treatment with the surface of the process, and screen printing similar printing, through the laser carving can be typed on the product surface or pattern.



Textured:the use of chemicals such as concentrated sulfuric acid on the plastic molding mold internal corrosion, the formation of serpentine, erosion, plow and other forms of the pattern, the plastic mold through the mold, the surface has a corresponding pattern of a process.
