1. Durable
Use P20 pre-hardened steel as the PET jar Preform Mould plate to make complete structure stable, not easy transformation.
All the mould plate rust-proof handling, decrease the second pollution during the production.
Core, cavity and screw all use S136 stainless steel. After the vacuum treatment, hardness 48-50HRC. Guarantee: 5 million shots.
2. High effiency and Low cost
using Germany heating ring HOTSET only 268W, the traditional one 320W, save 20% electricity cost. Lower AA level and be more environmental.
Hot runner production, save labor cost. One worker can work for 3 or 4 sets of injection machine
Large diameter pipe make the mould cool fast and well. Shorten cycle time.
Adopt double ejection device, pulley sliding and ejector sleeve to make sure the preform can be ejected smoothly without the robot hand.
3. High Accuracy and Easy maintaince
With high precision imported machine tool, all the spare parts can be interchanged to save the maintaince time and guarantee the preform weight difference.
Independent hot runner system, even one cavity is broken, others still work.
The temperature controller is controlled by PID. It can be changed on working condition.
Core, cavity and neck screw is controlled by the double cone positioning to ensure does not appear flash, different size, irregualr and other defects.
