Surface finishing
Surface finishing refers to different processes that making a specific appearance of a surface of the prototype parts ,to give it a distinct or desired look and feel. Different techniques are used to reach the effects. Bofong offers a high quality surface finishing service for all components and parts produced by different kinds of manufacturing method. We have a skillful team which proceed the job properly and professionally.
High Gloss Polishing
Sanding & polishing is one of the most common finish for prototyping. Sanding is very basic process to remove cutting marks or the printing marks, in order to get smooth surface. Get ready for further finish such as sandblasted, painted, chromed…
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.
Painting
Painting is a very flexible way to create different surface appearance.
We can achieve:Matt, Satin, High Gloss, Texture（Light & Heavy)
Powder coating
Powder coating is a dry finishing process that has become extremely popular since its introduction in North America over in the 1960s. Representing over 15% of the total industrial finishing market, powder is used on a wide array of products. More and more companies specify powder coatings for a high-quality, durable finish, allowing for maximized production, improved efficiency, and simplified environmental compliance. Used as functional (protective) and decorative finishes, powder coatings are available in an almost limitless range of colors and textures, and technological advancements have resulted in excellent performance properties.
Tinted （Dyeing）
Dyeing is the application of dyes or pigments one materials with the goal of achieving color with desired color fastness. Dyeing is normally done in a special solution containing dyes and particular chemical material Material suit for tinted: ABS , PMMA, PC, PS
Anodizing
The most popular way to create decent surface for electronic products. Apple almost use anodized for all their products.
Silk-Screen Printing
Silk-screen printing is one of the most popular printing techniques, and is the most-used by companies when printing designs onto products of different sizes and materials.
Silkscreen Printing is a stenciling method that involves printing ink through stencils that are supported by a porous fabric mesh stretched across a frame called a screen. Silkscreen Printing is ideally suited for bold and graphic designs.
Pad Printing
Pad printing is an indirect offset printing process, where an image is transferred via a soft silicone pad onto the surface to be printed.
Laser Engraving
Laser engraving is a process where the laser beam physically removes the surface of the material to expose a cavity that reveals an image at eye level. The laser creates high heat during the engraving process, which essentially causes the material to vaporize
Blasted
Blasting adds a uniform matte or satin surface finish on a machined part, removing the tool marks. This is used mainly for visual purposes and comes in several different grits which indicate the size of the bombarding pellets.
Plating
Plating is a surface covering in which a metal is deposited on a conductive surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for radiation shielding, and for other purposes.
Vapor Polishing
It is a kind of specialized treatment which we use to make parts more bright and clear. Mostly it is for polycarbonate (PC) plastic. We can also use this kind of method to to repair small defects in the surface of parts. This process can make a very good and clear surface complicated shape parts or hard to reach areas.
It was carried out like this : sanding the part up to #1500 grit carefully , then placed in an atmospherically controlled environment. After that, use Weldon 4 gas to melt the surface of the plastic at the molecular level, then all the small scratches becoming clearer and clearer.
