What is Surface Finishing

Surface treatment is the process of artificially forming a surface layer with different mechanical, physical and chemical properties of the substrate on the surface of the substrate. The purpose is to meet the corrosion resistance, wear resistance, decoration or other special functional requirements of the product. Different techniques are used to improve the appearance, adherence, solder-ability, resistance to corrosion, hardness, conductivity and many other characteristics of industrial components.

Painting	Flexible way to create a different surface appearance. We can achieve MatteSatinHigh GlossTexture ( Spangle & Heavy )Soft Touch (Rubber Spanke)UV coatingE-coating
Anodizing	Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. The most popular way to create a decent surface for electronic products. Apple almost uses anodized for all their products. We are offering: Anodized Type 1Anodized Type 2Anodized Type 3Chemical Film/Alodine
Chroming &Plating (Galvanized, gilded, silvering)	Plating is uses electrolysis to attach a metal film to the surface of metal or other materials to prevent metal oxidation (such as rust), improve wear resistance, con-ductivity, reflectivity, and corrosion resistance (copper sulfate, etc.), and enhance beauty.

Powder Coaing	Powder coating is a type of coating that is applied as a free-flowing, dry powder. it is typically applied electrostatically and then cured under heat or with ultraviolet light. which is a strong, wear-resistant finish. Powder coating is mainly used for coating of metals, such as household appliances, aluminium extrusions, drum hardware, automobiles, and bicycle frames.
Logo & Symbol	There are various ways to create a logo, symbol, and text on your prototypes or production parts. We can offer: Silk-ScreenPad PrintingRub onLaser Engraving
Sanding	Smooth sanding can remove machining marks, burrs, machine lines, and adhesive marks on the surface of the parts. The flatness of the part will be improved and roughness will be reduced to create a smooth and uniform look.
Polishing	Started from rough sand paper, when you reach 2000 sand paper the part surface are smooth enough for high gloss polishing to obtain shiny surface or mirror look, transparent such as light guide, lens.
Sandblasting/Bead blasting	Sandblasting is the operation of forcibly propelling a stream of abrasive maternal against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants.
Brushing	The wire drawing finishing process is a surface treatment method, that forms a line pattern on the surface of the workpiece by polishing, the product to achieve a decorative effect.
Knurling	Knurling is a manufacturing process, typically conducted on a lathe, whereby a patter of straight, angled or crossed lines is rolled into the.

FAQ

1.How to deal with surface treatment problems?

Sample color identification and dispensing ensure batch color consistency, strengthen manual inspection, avoid the defective products.
2.What is the best pre-treatment for prepping Aluminium castings?

Sandblasting Aluminium castings prior to finish is most common. E-coating would be a great economical operation. Chemical film is another treatment. It acts as an excellent primer for wet coat finishes on Aluminium.
3.How surface finishing works?

Almost all surface finishing processes improve either the aesthetic appearance of the product or its mechanical or chemical properties. Each surface finishing process achieves this in a slightly different way.
4.How much material is removed during the Sandblasting process?

During the Sandblasting process, the surface of a part is peened off, no part material is removed or lost at all. This process is typically used to soften parting lines or eliminate any sharp edges that could impact your line workers in the assembly process. It can also be used to give a uniform finish.
5.What the benefits of surface finishes?

Improve the appearance of your finished products, Improve resistance to wear and tear, Ensure good adhesion of paint, Meet your brand requirements...
