Heating of moulds

TYPE 4776, TYPE 4777

The heating unit of a cylindrical shape is made of stainless steel with a grinded surface. It is equipped with connecting leads CSA 1 mm².

The heating element is intended for heating of injection moulds for plastics up to maximum temperature of 325 °C.

Recommendations:
1. The opening for insertion of the heating element should be made within tolerance H7 and with surface roughness 0,4 m maximum. The length of the opening should be 2 mm longer than the length of the element.
2. Do not operate the element at the maximum power. Allow a reserve about 20 – 30%.
3. Use preferably a continuous temperature control. Repeated turning on and off could lower the lifetime of the element.
