PVC plastic injection molding process is the first condition.
Need a DKM injection molding machine professional PVC injection molding machine.
The temperature of the second cylinder must be precisely controlled.
Turn left | to the right.
Third, because PVC plastic fluidity is not good so must open side gate.
The first paragraph of the fourth injection molding machine must be filled with high speed and high pressure.

UPVC injection molding process.
PVC is also known as hard PVC. It is an amorphous thermoplastic resin made by polymerization of vinyl chloride monomer and is composed of certain additives (such as stabilizers, lubricants, fillers, etc.).
In addition to additives, the method of blending with other resins is used to make it have obvious practical value.These resins include CPVC, PE, ABS, EVA, MBS, etc.
The melt viscosity of UPVC is high and the fluidity is poor. Even if the injection pressure and melt temperature are increased, the change of fluidity is not significant.In addition, the molding temperature of the resin is very close to the thermal decomposition temperature, and the temperature range that can be formed is very narrow, which is a difficult material to form.
