ABS丨Acetal 丨CPVC丨 HDPE | LDPE丨 Nylon丨 PEEK丨 PEI | PET丨PMMA丨Polycarbonate | Polypropylene 丨 POM(Delrin) | PPSU 丨HIPS丨 PSU丨 PTFE丨 PVC
We offer a comprehensive suite of post-machining treatments to enhance durability, aesthetics, and functionality – all integrated seamlessly after CNC milling, turning, or laser cutting. Our corrosion-resistant coatings ensure parts withstand humidity, chemicals, and long-term wear — critical for aerospace, automotive, and medical industries.
CNC Part Polishing — Mechanical or electropolishing to Ra <0.8μm mirror finish. Ideal for medical implants, optical housings, and hygiene-critical custom machined parts.
High-pressure media abrasion for uniform matte textures (Ra 1.6-3.2μm), removing contaminants and enhancing coating adhesion by 25% – ideal for industrial enclosures and electronics housings.
Electrostatic application for thick, uniform layers (50-150μm) in custom colors, ideal for automotive parts needing impact protection.
Type II/III anodizing for custom CNC aluminum parts — 20% better corrosion resistance in harsh environments. Standard for aerospace brackets, drone frames, and enclosures.
Chemical immersion in nitric acid for stainless steel, forming a passive chromium oxide film to boost corrosion resistance by 40% – essential for medical instruments and food processing components.
Electro-deposition of thin chrome layers (5-50μm) for hardness up to 800 HV, increasing wear resistance by 30% – suited for automotive fittings and heavy-duty industrial tools.
