۞ Directions Of Magnetization

۞ Surface Protection

Besides from the effort of manufacturing high performance NdFeB material, our factory is also very keen on R&D on surface plating technology. We have introduced advanced automatic electroplate production line to improve continuously the surface plating quality. We are able to provide reliable high quality Nickel, Zinc, Epoxy platings, etc. The products show high toughness against salt spray test and constant temperature & humidity test.

The plating processes follows environment regulations , and all plating meets the ROHS standards.

Plating type	Plating Thickness	Colour	Working Temperature	Salt Spray Test	PCT	Characteristic
Nickel	10-30 μm	Bright Silver	≤200°C	≥96hr	≥48hr	Good performance under salt spray test and constant temperature & humidity test. Suitable for clean environments
Zinc	5-10 μm	Dark Silver	≤160°C	≥48hr		Suitable for common products
Epoxy	10-30 μm	Char Grey	≤120°C	≥96hr	≥24hr	Good performance under salt spray test and constant temperature & humidity test.

Note: For different products, the Salt Spray Test and PCT time varies with the shape of the product.
