PVC Special Injection Molding Machine
 |
Special screw with particular thread design, for rigid PVC, UPVC, CPVC, powered PVC, without backstop ring and trust ring, plasticizing efficiency will be highly improved, with better stability, the product will be more perfect.
The screw surface will be processed with hard chrome plating, the hardness can be above HRC65. With good smoothly surface, wear resistance and corrosion resistance, the working life will be longer. |
 |
On the barrel equipped with multistage air fan unit to ensure the temperature precise of melting, highly improved the qualified rate.
Enlarged the hydraulic charging motor in order to improve the torque force and slow down the speed, providing better conditions for production. |
Specially extended width of guard door for thr design of PVC fitting mould( specially for the mould with core- pulling oil cylinder)
