Happy Chinese New Year: BaiChuan’s holiday arrangements

Solvent vapor finishing is a reliable method for improving the surface quality of CNC-machined plastics. Carefully softening the outer polymer layer removes machining marks, enhances gloss, and restores clarity, particularly in transparent materials such as acrylic and polycarbonate.

Surface finishing in CNC machining is not just cosmetic but a critical functional requirement. Each finishing technique has specific strengths – grinding offers dimensional control, lapping achieves superior flatness, electropolishing provides cleanliness for medical components, and anodizing protects aluminum parts. Choosing the right finish depends on your part’s application and material, directly impacting component performance and service life.
