Cast Copper Heating Ring Uses and Features: Mainly used in the barrel heating device of plastic extruders, featuring reasonable structure, attractive appearance, stable performance, fast heating, uniform heat dissipation, good insulation performance, and high voltage resistance. Especially suitable for high temperature and high power requirements.
Cast Copper Heating Ring Technical Parameters:
1. Leakage current and electrical strength at working temperature. a) Leakage current (0.5mA b) Electrical strength: 1250V1min without flashover or breakdown.
2. Moisture resistance. Placed in a humidity chamber at 20-30°C with relative humidity of 91%-95% for 48h, no damage.
3. Tensile strength of lead-out rod. Withstand 70% of the tensile force of the part for 3 minutes without displacement or fracture.
4. Power deviation rate (±5%). 5. Withstand high voltage) 1500
