Injection temperature of PVC lay flat hose


If the size and process conditions of the main runner and gate are normal, the pressure value of the shrinkage fluctuation range of the plastic-coated PVC lay flat hose is usually obtained. The cooling time mainly depends on the thickness of PVC lay flat hose, the thermal and crystalline properties of plastics, and the temperature of moulds. The end point of cooling time should be based on the principle of ensuring that no change occurs during the demoulding of PVC lay flat hose. The cooling time is generally between 30 and 120 seconds. It is unnecessary for the cooling time to be too long. It not only reduces the production efficiency, but also makes demoulding difficult for complex PVC lay flat hose, and even produces demoulding stress when demoulding is forced. The other time in the forming cycle of PVC lay flat hose is related to the continuity and automation of production process and the degree of continuity and automation.

The auxiliary operation stage of the PVC lay flat hose forming cycle is all operations except the forming operation stage, which usually includes the opening and closing of the steel mould, the placement of inserts, the application of demoulding agents and the removal of products. As the plastic-coated PVC lay flat hose is modeled and shaped in a closed steel die cavity, the forming time should be included in the locking time of the steel die, while the movement time and auxiliary time of the moving parts should be included in the opening time of the steel die.
