220v cast copper mold electric band heater

product description

The cast copper heater is a tubular electric heating element as the heating element, which is reasonably bent and formed. After entering the mold, it is cast into various shapes with brass materials, including disc, flat, right angle, external air cooling, internal air cooling, and water cooling And other special shapes. After finishing processing, the cast copper electric heater has a smooth surface without casting defects. It can fit closely with the heated body. The surface load of the cast copper heater can reach 1-5W/cm². The working temperature is normal temperature -600℃. The electric heater is a material with good heating performance of metal casting. The overall heating of the heater is uniform, and the surface processing is smooth, which reduces the temperature difference on the surface of the equipment; it has a long life, good heat preservation performance, strong mechanical properties, corrosion resistance, and Increase the heat preservation device on the heat dissipation surface, which can save about 30% of electricity

Industry Application

It is widely used in extruders, injection molding machines, plastic machinery, packaging machinery, die head moulds, cable machinery, high temperature moulds, pipelines, chemicals, rubber, petroleum and other equipment.
