Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property. GD Prototyping provides an integrated parts surface finishing service to meet your diverse needs. With our experienced in-house skills and advanced facilities, we try our best to ensure the color, texture, gloss, and surface finish of parts and exceed your expectations.

Here listed most of the surface finishing services GD Prototyping do for you:

1. Manual Processing: Prototypes made by CNC, SLA and Vacuum Casting are sampled, polished and assembled. This procedure is to assemble all parts into a finished product.
2. Painting: Prototypes that have been made according to customer's requirements, sprayed with color in the dust-free oil room environment, so that the prototypes are more vivid, vibrant and increase the real sense of them.
3. Screen Printing: Printing words or patterns on the flat surface of the sample of prototype that have already made.
4. Pad printing: Printing words or patterns on the uneven surface of the prototype. This process need to add a piece of steel plate based on screen printing.
5. Laser engraving: Remove paint from the surface of the product with laser to make part of it transparent. For example the prototype of mobile phone buttons, car DVD buttons, lenses, etc.
6. Electroplating: A silver product color is applied to make some of the details of the product stand out. The sample must be very smooth before plating, there can not be any traces of impurities, and then immersed in chemical solution. This process is divided into: water plating and vacuum vapor deposition.
7. Oxidation: i.e. anodizing, which causes an oxidation reaction on the surface of aluminium, forming a film that makes the product less susceptible to scratching.
8. Wire Drawing: Pulling a thin trace on the surface of aluminium to give the sample a better texture.
9. Highlighting: On the aluminium samples that have already been well finished, is then machined with high-speed CNC to reveal the original color of the aluminium.
10. UV varnishing: Spray a layer of transparent oil on the surface of the product and bake it with UV light to make the product brighter and more wear-resistant and water-resistant, like a protective layer.
11. Sandblasting: Spraying a layer of sand-like effect on the surface of a piece of prototype to make the it look more perfect.
12. Mold Texture: Texture is mainly used for plastic materials and are mainly white, black and grey in color. It is extremely common in the production of prototypes.
13. Rubber oil: Spray a layer of transparent rubber oil on the surface of the sprayed product, so that the product has a rubbery and comfortable feeling when you hold it in hand.

Finishing processes may be employed for the purpose of appearance improvement, adhesion, corrosion resistance, tarnish resistance, chemical resistance, wear resistance, hardness, modify electrical conductivity, remove burrs and other surface flaws, and control the surface friction.

Whether it is CNC machined, vacuum casting, or 3D printed parts, to gain an accurate appearance of your final product, the prototype must undergo a rigorous post finishing process, we make it better by applying a variety of treatments to improve their appearance, performance and durability.
