Molding cycle of PVC lay flat hose


Injection moulding of PVC lay flat hose is a cyclic process. The moulding cycle mainly consists of storage time, injection holding time, cooling time, opening and closing time, ejection and removal time, product cooling and screw metering storage are carried out at the same time. Then the forming cycle of coated PVC lay flat hose includes the following parts.

PVC lay flat hose forming cycle directly affects labor productivity and equipment utilization. Therefore, in the production process, it is necessary to shorten the relevant time in the molding cycle as much as possible on the premise of ensuring the quality of PVC lay flat hose. Injection time and cooling time are more important in the whole molding cycle of PVC lay flat hose, which have a decisive impact on the quality of products. The filling time in injection time is directly inversely proportional to the filling rate, and the filling time in production is generally about 3-5 seconds.

Pressure holding time in injection time is the pressure time on the plastic in the cavity. The proportion of pressure holding time in the whole injection time of PVC lay flat hose is large, generally about 20-120 seconds (extra-thick parts can be up to 5-10 minutes). Before the freezing of the melt at the gate, the holding time has an effect on the dimensional accuracy of the product, but in the future, it has no effect. Pressure holding time also exists. It is known that PVC lay flat hose depends on material temperature, mold temperature of PVC lay flat hose and the size of main runner and gate.
