1, T for the isotropic material
2, each material grade can be selected according to customer requirements of different polymer plastics, such as PA6, PA12, PPS, etc., the corresponding products of the highest operating temperature: PA6: 150 ?; PA12: 120 ?; PPS: 180 ? .
Injection ferrite magnets is to use ferrite powder mixed with polymer plastic by injection molding mold the shape of permanent magnet for a variety of products, oriented in the molding process to get the sex products.
