Among those famous extruder hopper magnets manufacturers, it is a professional supplier in China, welcome to wholesale grate magnets in housing, rare earth grate magnets, magnetic quick grids, magnetic hopper grate, extrusion hopper magnets from our factory.Hopper Magnets for Injection Molding MachineMagnets for injection molding machine hoppers - temperature resistance of up to 120 °C At present we are offering also magnets to be installed into injection molding hoppers, with a temperature resistance of up to 120 °C. They are also equipped with very strong NdFeB rare-earth magnets, but with remarkably higher temperature resistance.Possibility of demagnetizing is the top benefit of the magnet. Demagnetizing can be carried out by loosening a locking screw and shifting magnetic cores out of stainless steel tubes. Due to this feature, cleaning job is very quick, comfortable and the trapped metal particles will fall off.Features :· Long lasting: Lifetime Guarantee of Permanent Magnet Strength· High surface gauss: Less than 1% magnetic loss in 100 years· Non-pollution: pharmaceutical, food grade and 3A dairy metal finishes available· Low energy consumption: Low maintenance costs· Finest of Magnetic Materials used meeting IMA/MMPALead time:  Equipped with standard magnetic bar size, 7-10 days;Customized made magnetic bars are acceptable, within 10-15 days.Specification:Length is adjustable as per customers’ request.The round style hopper magnets are available in 16 standard diameters ranging from 4" to 36" with either Ceramic or Rare Earth magnetic construction.
