Industrial Electroplating & Surface Coating Services
Electroplating is the process of depositing a thin layer of metal onto a substrate to modify its physical properties. It is the primary method for adding corrosion resistance, wear resistance, electrical conductivity, or pure aesthetic appeal to machined and fabricated parts.
At JUCHENG, we offer a comprehensive range of plating solutions tailored to your specific application. From cost-effective Zinc Plating for mild steel brackets to high-precision Electroless Nickel for complex aluminum geometries, our finishes meet strict industrial standards (ASTM/ISO) and environmental regulations (RoHS/REACH). Whether you need Rack Plating for delicate precision parts or Barrel Plating for high-volume fasteners, we ensure consistent coverage and adhesion.

Plating
JUCHENG’s Plating Spectrum
We manage diverse bath chemistries to achieve functional and cosmetic goals:
- Zinc Plating: The standard for corrosion protection on steel. Available with Clear (Blue), Yellow (Iridescent), or Black chromate conversion coatings.
- Nickel Plating: Offers excellent wear resistance and a bright, silver-like appearance. We offer both Electrolytic Nickel (brighter) and Electroless Nickel (uniform thickness on complex shapes).
- Chrome Plating: Hard Chrome for industrial wear surfaces (hydraulic rods) and Decorative Chrome for automotive trim appeal.
- Precious Metals: Gold and Silver plating for low contact resistance and high conductivity in electronic components.
- Tin Plating: Essential for solderability on copper busbars and terminals.
- Thickness Control: We use X-Ray Fluorescence (XRF) to verify plating thickness down to the micron level (e.g., 5µm Zinc or 0.5µm Gold).

Materials Available
Substrate Compatibility
We can plate onto most metals, but preparation varies:
| Base Material | Recommended Plating | Purpose |
| Mild Steel (1018/A36) | Zinc / Nickel | Crucial for rust prevention. Zinc is most economical. |
| Aluminum (6061/5052) | Electroless Nickel / Anodizing | Nickel provides a hard, conductive surface (unlike Anodizing). Requires zincate pre-treatment. |
| Copper & Brass | Tin / Silver / Gold | Enhances solderability and prevents oxidation (tarnish). |
| Stainless Steel | Electropolishing / Passivation | Usually passivated, but can be Gold/Nickel plated for specific functions. |
| Plastic (ABS) | Decorative Chrome | Specialized process to metalize plastic for automotive trim. |

Choosing the right finish for steel protection:
| Feature | Zinc Plating | Nickel Plating | Chrome Plating (Hard) |
| Primary Function | Sacrificial Corrosion Protection | Wear & Corrosion Resistance | Extreme Wear & Low Friction |
| Appearance | Bright, Yellow, or Black | Warm Silver / Yellowish | Cool Blue-White |
| Cost | Low | Medium | High |
| Hardness | Low | Medium/High (Electroless) | Very High (65-70 HRC) |
| Typical Use | Brackets, Fasteners, Chassis | Decorative trim, Electronic housings | Hydraulic shafts, Molds |
Why Choose Us
- Adhesion Testing: We perform bake tests and cross-hatch tests to ensure the plating does not blister or peel.
- Salt Spray Testing: We validate corrosion resistance (e.g., 96 hours to white rust) in our salt spray chamber for critical outdoor parts.
- Precise Masking: We mask threads and critical bores to prevent plating buildup from interfering with assembly tolerances.
- Hydrogen Embrittlement Relief: For high-strength steels, we perform post-plate baking to prevent hydrogen embrittlement failure.
Advantages
- Barrier Protection: Creates a physical barrier against moisture and chemicals.
- Sacrificial Action (Zinc): Zinc protects steel by corroding first (galvanic protection), even if scratched.
- Solderability: Tin and Gold plating allow components to be easily soldered onto PCBs.
- Hardness & Lubricity: Coatings like Hard Chrome or Nickel Boron reduce friction and wear on moving parts.
Industries Served
- Electronics: Connectors, pins, EMI shielding cans (Tin/Gold).
- Automobil: Engine bolts (Zinc), interior trim (Chrome), fuel system parts (Electroless Nickel).
- Industrial Machinery: Hydraulic rams, gears, shafts (Hard Chrome).
- Energy: Busbars for switchgear and battery packs (Silver/Tin).
- Telecommunications: RF filters and housings (Silver/Alodine).
