Finishing and Surface Treatment Services
Service Detail from Pexco

High-performance plastic components often require specialized surface finishing and heat treatment processes to achieve optimal performance:
Vapor Polishing
Creates optically clear, defect-free surfaces on transparent and translucent plastics by briefly exposing machined parts to solvent vapor that smooths surface irregularities at the molecular level. Eliminates machining marks and achieves glass-like clarity without dimensional changes, ideal for optical components, medical devices, and high-visibility applications.
Annealing and Stress Relieving
Remove internal stresses introduced during machining, preventing dimensional instability, cracking, or warpage in service. Our controlled thermal processing optimizes material properties and dimensional stability, particularly important for precision components operating in demanding thermal environments or requiring long-term dimensional consistency.
Additional Finishing Options
Flame polishing, mechanical buffing, and surface texturing to meet specific functional or aesthetic requirements.
