Plastic Injection Molding Machine HSJ Series

i-Master HSJ series plastic injection molding machine can deal with general purpose thermoplastics such as PolyEthylene(PE), PolyProplene(PP), PolyVinyl Chloride(PVC), PolyStyrene(PS), Nylon, PolyCarbonate(PC), Acrylonitrile Butadiene Styrene Copolymer(ABS), etc.

Specially designed HSJ series PET injection molding machine meets the processing requirements of PET material at most.

• KPET8;
• KPET12;
• KPET16;
• KPET24;
• KPET32.

• HIPET-48;

• Robust box style mold platen by direct iron casting;
• Larger mold capacity (opening stroke, mold thickness and space between tie-bars);
• (Optional) Differential injection device and clamping unit (higher speed but lower pressure);
• Self-lubricating bushes used in guide rods and tie-bars for smooth running and eliminating the need of external lubrication of machine surfaces and plastic goods.
