Why Surface Finishing Matters?

Surface finishing is more than just making a part look good; it is about engineering the surface properties to meet specific environmental and operational demands. Whether you need to improve corrosion resistance with Anodizing, increase surface hardness with Heat Treatment, or achieve a specific brand color with Painting, JUCHENG integrates these processes into our manufacturing workflow.
We manage the entire finishing process—either in-house or through our network of certified aerospace/medical-grade partners—ensuring that your parts arrive fully finished and ready for assembly, saving you the logistical headache of managing multiple vendors.

Plastics Spray Painting, Metallization (EMI shielding), Vapor Smoothing, Dyeing.
Titanium Anodizing (Type II), Polishing, PVD Coating.

Quality Assurance for Finishes

Validating Your Finish
A finish is only as good as its adhesion and thickness. JUCHENG employs strict QC protocols:
  • Color Verification: Using X-Rite spectrophotometers to ensure Delta-E consistency for paints and anodizing.
  • Thickness Testing: Utilizing eddy-current and ultrasonic gauges to measure coating thickness (e.g., ensuring 25µm for hard anodize).
  • Adhesion Testing: Performing cross-cut tape tests (ASTM D3359) to verify paint and powder coating bond strength.
  • Salt Spray Test: Validating corrosion resistance for plated and coated parts destined for marine or outdoor use.

Advantages of JUCHENG Finishing

The JUCHENG Finishing Advantage
  • Integrated Workflow: Parts move seamlessly from machining to finishing, reducing lead times and handling damage.
  • Cosmetic Standards: We categorize parts into Class A (Visual), Class B, and Class C surfaces, applying inspection criteria appropriate to your needs.
  • Masking Expertise: We specialize in complex masking, allowing for dual finishes (e.g., anodized body with conductive masked grounding points) on a single part.
  • Global Compliance: All our finishes are RoHS and REACH compliant for global export.

Industries & Applications

Industries Demanding Perfection
  • Consumer Electronics: Aesthetic aluminum housings with sandblasted and anodized finishes.
  • Medical: Passivated stainless steel surgical tools and painted diagnostic equipment.
  • Automobil: Chrome-plated interior trim and zinc-plated chassis components.
  • Aerospace: Hard anodized flight control components and chemical film coated avionics chassis.
  • Industrial: Black oxide hardened gears and powder coated machine guards.
