PVC pipe fitting production and output quantity steady growthly all over the world. How to choose a suitable PVC powder special injection molding machine will be a big difficult problem to manufacturers.

1.only screw type injection machine, can’t use plunger type injection machine.

2.All of the parts will get in touch with PVC material can’t bring detain or adhere to the plasticizing solution. Because of the HC1 function will require these parts wear resistance and corrosion resistance. We’d better choose Wear resistant and corrosion resistant material manufacturing equipment, or make chrome plating or nitriding treatment equipment.

3.The equipment temperature control system must be with definite index and quick reaction.

4.Screw R/D is small, the nozzle of the screw is sharp end. Screw reduction ratio is 2-2.5. and three length of the screw can be settled with 40%, 40% and 20%.

5.Adopt larger nozzle hole and fit with heating temperature controller device.

6.Closed loop control is used in electric heating system, control material temperature tolerance strictly, the best tolerance is +-15 degree.  Injection nozzle has single and temperature controller system.

7.Material pipe group should with cooling device, we suggest add some fans to cooler injection tube temperature.
