Durable Powder Coating Solutions for Industrial Applications
Powder Coating is the superior choice for finishing metal parts that require toughness, corrosion resistance, and aesthetic appeal. Unlike traditional wet paint, powder coating applies a dry, free-flowing thermoplastic powder electrostatically, which is then cured under heat to form a "skin." This results in a finish that is significantly thicker, harder, and more resistant to chipping and scratching than standard liquid paints.
At JUCHENG, we integrate powder coating into our manufacturing line to provide a seamless "part-to-product" service. Our facility handles everything from pre-treatment (cleaning and sandblasting) to automated spraying and curing. Whether you need a high-gloss finish for a consumer appliance or a rugged textured finish for heavy machinery, we ensure your parts are protected and professional.
Powder Coating

JUCHENG’s Coating Capacities

A great finish starts with preparation. Our process ensures maximum adhesion and longevity:
  • Surface Pre-Treatment: We don't just spray over dirt. We utilize multi-stage chemical cleaning (degreasing/phosphating) or mechanical blasting to create the perfect surface profile for adhesion.
  • Color & Texture Variety: We stock a vast library of RAL and Pantone powders. Finishes include High Gloss, Matte, Satin, Sand Texture, Wrinkle, and Metallic effects.
  • Precision Masking: We use high-temperature silicone caps and tapes to mask threads, bores, and grounding points, ensuring they remain paint-free and functional.
  • Large Part Capacity: Our curing ovens can accommodate large frames, chassis, and panels up to 3 meters in length.
  • Eco-Friendly: Our process involves zero VOCs (Volatile Organic Compounds) and recycles overspray, making it an environmentally responsible choice.

Materials Available

Suitable Substrates for Powder Coating
Powder coating requires the part to be conductive and withstand oven temperatures (~200°C). Ideally suited for metals:
Material Class Why Powder Coat? Pre-Treatment Recommendation
Mild Steel (SPCC/Q235) Essential for rust prevention. Sandblasting or Iron Phosphate cleaning.
Aluminum Adds durability and color. Chromate Conversion (Alodine) for max adhesion.
Stainless Steel For aesthetics (changing color). Surface roughening (blasting) required for grip.
Galvanized Steel Fine CeramicDouble protection (Duplex System). Degassing cycle required to prevent bubbles.
Zinc / Magnesium Castings Hides surface porosity defects. Thermal degassing to prevent outgassing bubbles.

Why Choose Us

  • Adhesion Guarantee: We perform cross-hatch adhesion testing (ASTM D3359) to ensure the coating won't peel or flake under stress.
  • Thickness Control: We maintain a consistent film thickness (typically 60-80 microns) to ensure durability without interfering with assembly fit.
  • Visual Standards: Parts are inspected under standardized lighting to ensure color consistency and freedom from defects like "orange peel," pinholes, or inclusions.
  • Packaging: Coated parts are individually wrapped in foam or bubble wrap to prevent scratches during shipping.

Advantages

  •  Toughness: It creates a polymer "skin" that is flexible enough to withstand vibration and impact better than brittle liquid paint.
  • Defect Hiding: Textured powders are excellent at hiding machining marks, die-cast flow lines, and minor surface imperfections, reducing the need for expensive hand polishing.
  • Uniformity: Electrostatic application ensures even coverage, wrapping around corners and coating complex shapes without drips or runs. 

Industries Served

  • Industrial Machinery: Frames, guards, brackets, and heavy-duty mounts.
  • Automotive: Wheels, chassis components, roll bars, suspension springs.
  • Architecture: Window frames, fencing, outdoor furniture, signage.
  • Electronics: Server racks, computer cases, electrical cabinets.
  • Appliances: Washing machines, fridge panels, microwave housings.
