ISO9001 Injection Molding SmFeN Magnetic Compound OEM For Motor For
Water Pump
Process flow
- 1. Use Samarium-Iron-Nitrogen magnetic powder to mix with PA12 or
or EPA, antioxidants and lubricants, and form pellets in a screw
extruder
- 2. The granules are sieved and weighed, and the properties are
measured and then packed into buckets or bags, and packed on
pallets
Application
- Injection molding SmFeN compouds are a kind of bonded products, and
are suitable for products formed by injection molding machines.
Because of the high precision of injection molding and integrated
molding with copper, stainless steel, plastic bearings and other
types of inlays, It can be used in micro motors, motor rotors and
sensors, automotive motors, and can also be used in household
appliances and toys
Feature
The density is 3.5-4.5g/cm3, and the product of the same volume is
more lightweight
Advantages of precise dimensions, light weight, thin walls and
complex shapes
Excellent anti-rust performance
Stable magnetic properties, can be bonded together with other metal
parts
In many electronic products with high precision and high
performance requirements, injection molding magnets can meet their
requirements
Injection molding NdFeB compouds are a kind of bonded NdFeB
products, and are suitable for products formed by injection molding
machines. Because of the high precision of injection molding and
integrated molding with copper, stainless steel, plastic bearings
and other types of inlays, It can be used in micro motors, motor
rotors and sensors, automotive motors, and can also be used in
household appliances and toys
Nano (Royce3010) chelated film without coating treatment can meet
the use in marine climate conditions for 20-30 years, and can be
widely used in sea-based wind power generation. The surface bonding
force is more than 20Mpa, which can be widely used in permanent
magnet high-speed motors, special motors, electric vehicle motors,
extra high voltage, high voltage DC power supply systems, fast
charging systems, aerospace and military industries, etc.
