Surface treatment is an important indicator to evaluate the quality of prototype.The quality of prototype is mainly reflected in whether its appearance can 100% meet the customer's design philosophy. Therefore, it is very important for the customer to describe the surface effect of the prototype objectively and realistically. Below we analyze some of the surface treatment processes that affect the prototype surface effect.


There are many reasons to choose anodizing on aluminum, magnesium or titanium. Anodizing helps to resist corrosion, increase surface hardness, improve resistance to wear and dissipate heat. Anodizing is an ideal surface treatment for painting and priming, and it looks great too.

We normally use sulfuric acid anodizing, which allows us to add tints or dyes to your parts for a variety of visual effects. Hard coat anodizing is also available for surfaces that need to be extra hard.

A great paint job is one of the best ways to make your product stand out from the crowd. Using only the finest PPG automotive polyurethanes, we can replicate virtually any color, tint or hue in our climate-controlled, automated spray room.

Our master painters can supply millions of colors, in matte, flat, semi-gloss or glossy finishes. We even create custom painted textures. We also have the highest ISO and BS certifications for quality and environmental protection so you can be rest assured that you’ll receive only the most professional and responsible painting service.

Color Matching

How can you be sure you get exactly the color you want? We can match any standard Pantone® or RGB color that you specify using our color mixing system. If you prefer, send us a sample part and we’ll use our X-Rite color tester to match it precisely. The X-Rite allows us to send color data to you wherever you are in the world and in real time, eliminating any guesswork. And our color-balanced viewing booth helps us to monitor our work so you get consistent results from one batch to another.

PANTONE® and other Pantone trademarks are the property of Pantone LLC. PANTONE color identification is solely for artistic purposes and not intended to be used for specification.

Printing and Etching

We have many ways to provide custom printing and marking of text and logos on your parts. We make custom stencils for pad printing on most flat or curved surfaces. Pad printing is fast, reliable, consistent and comes in many colors. Silk screening is also available for larger surfaces and when mixing multiple colors for even more complex graphics.

We can etch or engrave your graphics using an engraving tool, while laser etching is ideal for making the most precise and permanent marks on metal and and some plastics.

Sanding And Polishing

We take great care to offer the most professional finishing service for your prototype and production needs. This often involves fine hand sanding in a variety of grits to prepare your parts for later painting and plating.

Sanding is not just used for painting prep but to create the final surface finish. We can provide brushed and satin surfaces for a variety of metallic effects, and optically clear polishes on transparent acrylics. All of our work is done in a clean, well-lit, environmentally controlled model shop.

Vapor Polishing

This is a specialized treatment we do in-house for achieving optical clarity on polycarbonate (PC) plastic. This method can also be used for repairing minor surface defects, and is ideal for achieving an extremely clear surface on complex geometries or hard to reach areas.

After carefully preparing the part with sanding up to #1500 grit, it is then placed in an atmospherically controlled environment. Weldon 4 gas is used to melt the surface of the plastic at the molecular level, which rapidly reforms with all microscopic scratches blended out.

Blasting (metal material)

Blasting involves the controlled spraying of an abrasive media against the surface of your part. A variety of media can be used, including sand, garnet, walnut shells, water or metal beads.

Blasting is used to clean and deburr parts, preparing them both mechanically and chemically for later surface finishes. Blasting also imparts unique textures, frosting, pebbling, etc. Check out our blog to learn more about other popular methods for finishing a metal surface.

Some plastic prototype in order to achieve the metal surface specular effect, need to plate a layer 

metallics, this process is plastic prototype plating. Plating divided into water quality plating and 

vacuum plating. Need to be emphasized that only ABS material can be plated. The most common is a metallic silver surface coating on ABS.For the metallic prototype, can plating, oxidation and anodizing.

Water transfer printing technology

Water transfer printing technology is the latest digital imaging technology beyound any imaging technologies. It is using a special paper made of nano materials and special environmentally friendly ink to print images on any solid medium. Its biggest technical advantage is that it does not require special equipment or special consumable or high temerature heatign, is not limited by the medium. As long as you have image input tools (scanners or digital cameras), drawing tools (computers), image output tools (inkjet printers), plus water transfer inks, water transfer papers, you can work on any solid object, any print any images on the surface as you like, with vivid colors and absolute photo quality.
