Equipped with vacuum pump, pipeline, storage bin, hopper, dryer and other complete sets of equipment, ladder. (If the material is not mixed in advance - equipment and machine need to be configured - procurement confirmation) increase the meter weight device, in order to ensure the uniform coating of the insulation layer.

Adhesion requirements: the plastic should meet certain adhesion requirements after the coating, and the plastic should not break, whiten and other defects after bending.

Cooling device

Stepped cooling, prohibiting sharp cooling resulting in the decline of plastic adhesion; Hot water tank pump needs special consideration, water pipe at the bottom of the water tank comes with a valve; With line edge hot and cold water tank, water pump flow need to be calculated and adjusted
