Property and Use:
Cast aluminum heating loop is a kind of electric heater, using tube-shaped electric heating elements and a high-grade aluminum alloy shell, with a general operating temperature of 150��450. It is applicable to plastics machinery, die heads, cable machinery, and equipment in chemical, rubber, and petroleum industry, etc. Cast aluminum heater is featured by long service life, excellent heat-insulating properties, outstanding mechanical properties, corrosion resistance, and magnetic reactance, etc.

Ordering Instructions:
    1) Customers shall provide product drawings or samples; if drawings or samples are not available, please provide specifications, models, voltage, and power, etc. of the products.
    2) Power handling of the surface of cast aluminum heater is 2.5��4.0Watts/cm2.

Use Instructions:
    1) The working voltage shall not exceed the rated value by 10%;
    2) The wiring part shall be outside the heating layer and insulating layer; the shell shall have effective grounding;  
    3) Cast aluminum heating loop shall be placed in a dry place; if the insulation resistance is lower than 1M�� because it has been unused for a long period of time, please bake the resistance in an oven at 200 for 5-6 hours.
