Data Storage

Ultra-precise coating solutions for hard disk drives and data storage components.

Superior Surface Engineering specializes in precision electroless nickel plating for HDD components. Our processes meet the extreme tolerance and magnetic property requirements demanded by the data storage industry, ensuring every component performs flawlessly at nanometer-level precision.

Our Expertise

HDD Substrates

Precision electroless nickel plating for aluminum and glass substrates. Our coatings provide the ultra-smooth, defect-free surface required for high-density magnetic recording media with roughness values below 0.3nm Ra.

Disk Platters

NiP coatings with precisely controlled phosphorus content (10-13%) for optimal magnetic properties. Our proprietary process ensures uniform thickness across the entire platter surface with less than ±0.5μm variation.

Actuator Arms

Lightweight, precision-coated actuator components with controlled hardness and wear resistance. Our surface treatments enable fast seek times and extended operational life, supporting drives exceeding 500,000 load/unload cycles.
