High gloss polishing

With CNC machining services and rapid prototyping, achieving smooth surfaces is essential. The process begins with sanding to eliminate cutting or printing marks, ensuring a flawless base. As we progress to finer grits, like 2000 sandpaper, the surface becomes smooth enough for high gloss polishing, ideal for mirror-like finishes on transparent parts such as light guides and lenses. Additional options like sandblasting and painting are available for further enhancements.


Painting is a very flexible way to create a different surface appearance.We can achieve:
High GlossTexture (spanght & Heavy)
Soft Touch ( Rubber spanke)


Tinted is another option to color plastic prototypes besides painting. It is a good solution for turn signal, tail lamp.
