Due to different reasons, possibly for appearance or application under special condition, sometimes special plating needs to be adopted on magets, our company is in a good position to supply following surface treatment service: electroplating zinc, nickel, epoxy and other plating treatment. We are specialized in precision machining on super hard materials, esp. in micro-appliances including deep-hole thin wall ring magnet elements, enjoying a high competitiveness within market both at home and abroad. The specific shape and size can be available by producing according to different drawing designs from customers. The hole/(OD-ID)can be drilled to as tiny as 0.1mm for NdFeB and 0.2mm for SmCo at our end, they are mainly used to make into super hard micro magnetic precision parts for clock, watch, micro-motor, optical communication electronics, electroacoustics, digital camera.
Due to low anti-corrosive property for NdFeB Magnet, it may need surface treatment process for most occasions. We could offer our clients the following surface treatment: Zinc or Ni electroplating, Epoxy Coating and others.

The hole/(OD-ID)can be drilled to as tiny as 0.1mm for NdFeB and o.2mm for SmCo at our end, they are mainly used to make into super hard micro magnetic precision parts for clock, watch, micro-motor, optical communication electronics, electroacoustics, digital camera.
Parylene is a polymeric coating material that can be applied from the gas phase in vacuum. This unique parylene coating process, conducted at ambient temperatures, produces thin layers of polymer having superb uniformity and continuity and completeness of coverage. Parylene is a conformal polymer film that has been used as a protective conformal coating for more than 25 years. As a dry process non-solvent based coating, parylene is not affected by volatile organic compound (VOC) restrictions, and it is not implicated in the ozone depletion concerns of the Montreal Protocol and other environmental legislation. Parylene's pinhole free conformal coating protects coated substrates from moisture, chemicals, and electric charge. While Parylene is typically used to coat circuit boards or immobilize particles, it can also be removed from the original surface and used as a microstamp allowing MEMS patterns to be transferred reproducibly to polymers with various properties. Some desirable properties of the polymer Parylene (poly-para-xylylene) are: Biocompatibility;Truly conformal material (pin-hole free at 25 nm thickness);Thin film dielectric;Excellent moisture/chemical barrier properties;High mechanical strength.
Our product could be applied for parylene-coating well.
