Premium Surface Finishing Services for Custom Parts
The manufacturing process isn't complete until the finish is perfect. JUCHENG provides a one-stop solution for high-quality post-processing, enhancing the aesthetics, durability, and functionality of your CNC machined, sheet metal, and 3D printed components.
Surface Finishes

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.

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.
  • Automotive: 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.
