How to improve the quality of PVC lay flat hose by injection moulding process

Manufacturers in the production of PVC lay flat hose process, requirements are very strict, because quality is our focus, then what are the key factors?
In the whole process of injection moulding of PVC lay flat hose, great attention should be paid to the whole product design, moulds, equipment and raw materials of PVC lay flat hose. Because of the poor fluidity and high melting point of ordinary PVC lay flat hose, attention should be paid to the speed and pressure of injection moulding, and a certain high temperature should be required in order to fill the moulds and make the PVC lay flat. Hose is of better quality. Note that PVC lay flat hose can not have the shortcomings of stomata, markings, discoloration, black spots, fog halo, whitening, and that the transmittance of PVC lay flat hose is required to be higher.
This is the manufacturer’s requirement for the injection moulding process in the production of PVC lay flat hose. Only in this way can the quality of PVC lay flat hose be guaranteed.
