The process of using electrolysis to make the surface of metal or other material parts adhere to a layer of metal film so as to prevent metal oxidation, improve wear resistance, electrical conductivity, reflectivity, corrosion resistance and improve aesthetics. Hitions can also do PVD(Physical Vapor Deposition)

Laser caving

Laser carving(also called laser etching), use a laser beam to carve a permanent mark on the surface or inside the transparent material. The laser beam can produce chemical and biological effects and special effects on the material. When the material instantly absorbs the laser light, it will produce physical or chemical reactions, thus carving marks or displaying patterns or words.

Coloring process

For the coloring treatment of 3D printing products, manual coloring, spray painting, infection,before product shaping, we can also use colored PLA /  ABS consumables.

For subtractive production, Hitions have professional CMF engineers, we can customize your color requirement according to the Pantone color your team prefer.


use the impact of high-speed sand flow to clean and roughen the surface of the substrate, so that the surface of the workpiece to obtain a certain degree of cleanliness and different roughness,

Hitions can adjust the size of particle to achieve different surface feature.


Silkscreen is the most common way we adapt to make logo on prototypes. The ink is very thick and not easy to fade away , it can maintain the bright color for a long time.

Gluing and assembling

Disassembly printing or gasket design needs to be glued. It is better to apply glue by means of dots and bind with rubber bands to make the two contact surfaces contact more closely when bonding. During the bonding process, there will be gaps or rough contact in the model. Hitions use Bondo glue or filler to make it smooth.


Free deburring and paid exquisite hand polishing to obtain smooth and bright surface of the model.
