Pressed in Brass Coil Heater With Thermocouple J For Hot Runner System
1. Introduction
Pressed in brass coil heater can be made of various cross section heating filaments, such as square, round and flat, provide high-performance electric heater for heating hot runner mold and other fields. Heater maximum temperature up to 650 ºC, the integration of temperature thermocouple for the precise temperature control, can provide K, J, E thermocouple, blasting and blackening surface treatment, also can provide bright surface.
2. Characteristics
1) Very good performance of the heating uniformity in the heating area.
2) High insulation (more than 500M ohm) and high pressure resistance (1000V above), can meet special requirement if customers need.
3) The moisture-proof is IP65
