Application: Magnesium oxide (MgO) tubes are widely used in cartridge heater, tubular heaters, thermocouple, heating cable, hot runner heater and other speical electric heaters.

Physical performance: MgO tubes have good phyisical performance in high temperature resistance, electrical insulation and thermal conductivity.

Production process: We can make the precise extrusion mould per customer drawing dimension request, and choose the correct MgO material formual to meet customer actual request. Using automatic machine to form and advanced kiln firing the half-finished part with accurate and stable temperature to gurantee the parts in good quality. Then, cutting the parts with correct length request by customer, the parts will be very straight. We will check the dimensions to decide whether some distortion in the holes on the parts both sides and arrange 100% inspection for appearance of the tubes before shipment.
