Sealed Hot Runner Heater , Electric Resistance Heater For Plastic Injection Moulds

Sealed hot runner band heater coil heater with cover for plastic injection moulds

Description:

1)  Hot runner heater is an advanced concept of thermal engineering which has a construction similar to high watt density cartridge heaters. These heaters are also known as high performance tubular heaters or cable heaters. The basic construction of these heaters consist of compacted MgO, high temperature resistance wire and Chrome Nickel Steel tube. These heaters can be constructed with or without built in thermocouples. They are usually installed where space available for heating is limited and are widely used on hot runner nozzles, and manifolds, die cast nozzles, packaging machines etc.

2) A Coil Spring Heater in its unformed straight stage can have a maximum length of 6ft and its cross-section can be square or rectangular, while a cable heater can be 300ft long and is available in round cross sections. Thermocouple sensors could be installed internally at the tip or the middle of a heater.

Specification:

1) Thermocouple type : We manufacture it according to the Chinese Industrial Standard(CIS),and we can manufacture as your requirement..

2) A class unit price made with import material, with stable Temperature, and a long working life. B class unit price made with general material.

3) The normal cable length is 1000mm,also we can make the length as you need.

4) The leading wire type use fiberglass silicone copper wire ,PTFE wrapped copper wire ,and the others should be customized.

5) material :SS 304,Mgo,Heating coil

6) The normal voltage is 230V,we can make the voltage as you need.

7) Sleeve types A class watch with A1,A2,A3,B class watch with B1,B2,B3,The normal is B3.
