parellel twin-screw extruder heater

Cast-in heater Description:

Cast-in heater is a tubular electric heating element for heating body, and bending molding, into the mold with high quality metal alloy material for shell in centrifugal cast into various shapes, a round, flat, rectangular, air-cooled, water-cooled and other special-shaped etc.. After finishing it and heated body tightly, Metal casting heater is a kind of high efficiency heat uniformity division of the heater, thermal conductivity, excellent metal alloy, ensure the hot surface temperature uniformity, eliminating equipment hot and cold spots. With long life, good insulation properties, mechanical properties, corrosion resistance, magnetic resistance etc.. The outer radiating surface increases thermal insulation device, within the radiating surface of sintering infrared which can save 35% of electricity

Cast-in heater Feature:

1.cast aluminum surface load can reach 2.5-4.5w / cm2, maximum operating temperature 400-500 °C;

2.cast copper surface load can reach 3.5-5.0w / cm2, maximum operating temperature 600-700 °C;

3.cast iron surface load can reach 4.5-6.0w / cm2, maximum operating temperature 800-850 °C.

Cast-in heater Applications :

Widely used in Extrusion industries, Injection Moulding , Vaccum Forming Compression Moulding, etc.
