JYH Prototype combines 100+ precision machining centers, automated inspection, and in-depth metallurgy expertise to deliver components that meet the strictest international engineering tolerances and quality standards.
Up to 50µm thickness with Rockwell 65 HRC equivalent surface wear protection.
Vibrant, UV-stable dyed finishes: matte black, gunmetal, electric blue, red, gold, clear.
Tough electrostatic polyurethane and epoxy coatings in RAL and Pantone shades.
Uniform corrosion-resistant deposit inside complex holes and blind cavities.
Four critical manufacturing challenges solved by our Shenzhen factory engineering team through advanced machinery, smart toolpaths, and verified metrology protocols.
500 × 500 HD Natural
Cryogenically controlled sulfuric acid hardcoat anodizing produces a dense 50µm aluminum oxide layer impregnated with PTFE for supreme abrasion resistance and low friction.
500 × 500 HD Natural
Automated powder spray booths apply durable epoxy and polyester powders cured at 200°C, providing weather-proof, impact-resistant protection in smooth, fine-matte, or textured sand finishes.
500 × 500 HD Natural
Autocatalytic chemical nickel deposition ensures 100% uniform plating thickness across complex CNC geometry, internal threads, and blind holes without edge buildup.
500 × 500 HD Natural
Automated blast cabinets with ceramic and glass beads create uniform satin non-reflective textures (Ra 1.6µm), followed by optional optical hand polishing up to mirror SPI-A1.
Every part manufactured at JYH Prototype adheres to international engineering standards and rigorous metrology protocols.
