Our PVC/PPR Injection Molding Machine is dedicated for the PVC PPR manufacturing process with Low-temperature Plasticizing System, Eco-friendly and Energy-saving, Lower Hydraulic System Pressure, Shorter System Response Speed, Faster Injection / Shot Speed, Lower Molecular Internal Stress, Higher Tenacity & toughness Products.
Highlights for PVC PPR injection molding machines:
- At least 30% more energy saving than the traditional variable pump system (servo series)
- AC servo motor to achieve smooth motion even under low-speed (servo series)
- Higher repeatability of products with the use of the double closed loop control of flow and pressure
- Exceptional and stable performance under low pressure and low flow attained by the servo-driven hydraulic pumps
- Ultra- strong corrosion resistance thanks to the special screw of PVC powder that also ensures an even powder plasticisation
- Wider span between moulding area and movable door together with two sets of core pulling to better suit a range of PVC products
Optimized Designs for PVC PPR injection molding machines:
- Dedicated designed Bi-metalic Screw & Barrel for PVC,UPVC,CPVC,PVC Powder, PPR material. Stabilized temperature increasing rate from charging. Highly efficient plasticizing rate and stable injection molding. Product quality is excellent.
- High-Torsion/ Low- Rotation Hydraulic Pump. Efficient plasticized capacity. Reduce Cooling – time & Material- consumption.
- Dedicated designed for hard PVC mold, widened the plate metal,, convenient to mold installation. Reduce customer cost, increasing the safety of the operator.
- Adopted solid state relay to control temperature and ensure accurate temperature.
- Two groups of core-pulling, two in and two out of each group.
- Imported variable pump or servo drive control, energy saving is remarkable.
- Standard with fan and wind cover, make sure small material temperature deviation.
- Multiple sets of core-pulling and stainless steel screw are optional.
