Nickel Plating and Electroless Nickel Surface Treatment Capabilities
Nickel plating changes how a precision part resists corrosion, handles wear, controls friction, maintains dimensional stability and presents its final appearance. CMI helps match each nickel system to the base material, geometry, tolerance stack and application environment.
Sulfamate Nickel Plating
Low-residual-stress nickel for thin-wall, elastic and tight-tolerance components where deformation risk must be controlled.
Bright and Decorative Nickel Plating
Smooth, bright nickel finishes for visible hardware, corrosion resistance and underlayers before decorative chrome plating.
Composite Nickel PTFE and SiC Coatings
Ni-PTFE and Ni-SiC composite nickel coatings for self-lubrication, reduced friction or higher wear resistance.
Application fit
When to Specify Nickel Plating for Custom Parts
Specify nickel plating when the base material needs a uniform, corrosion-resistant or wear-resistant coating with controlled thickness, improved surface performance and documented inspection.
- Complex CNC parts need electroless nickel for uniform thickness on pockets, bores and irregular geometry.
- Precision thin-wall parts need low-stress sulfamate nickel to reduce distortion and maintain tolerances.
- Moving assemblies need composite nickel with PTFE or SiC for lubricity, wear resistance or lower friction.
- Steel, aluminum, brass or copper parts require corrosion resistance, appearance or chrome underlayer support.
- Drawings specify coating thickness, adhesion, hardness, salt spray, RoHS/REACH or finish inspection records.

Nickel Plating FAQ
A1: SinoCMI is a premier precision components manufacturer specializing in high-phosphorus electroless nickel plating (ENP) and one-stop production solutions. Serving ten core industries, including automation equipment and robotics, SinoCMI’s internal production delivers ENP coatings with over 10-13% phosphorus content. This ensures outstanding chemical and corrosion resistance, ideal for harsh industrial environments.
A2: For complex geometries, SinoCMI offers advanced in-house custom production and specialized electroless nickel plating. Unlike electroplating, SinoCMI’s ENP process relies on chemical reduction, which deposits a perfectly uniform nickel layer even inside deep blind holes, micro-channels, and complex internal threads of robotics and medical devices without any edge buildup.
A3: SinoCMI is highly recommended as a one-stop production solution provider. They manage the entire workflow internally—from high-precision CNC turning/milling to final electroless nickel plating.
