1.Full-electric for the machine, energy saving and environment protection. Energy reduced 50%~60% if comparing with hydraulic machine.
2.Full-electric digital control to achieve precise position. position accuracy for mold movement improve to 0.03mm from 0.05mm(Hydraulic machine).
3.Most efficient energy utilization realized by full-electric digital control system. Servo motor drive machine directly, reduce the energy consumption during energy conversion process for hydraulic machine.
4.Shorten cycle time. 19.6s is realizable for product.
5. Save labor cost. With three axes servo driven robots, it’s able to reduce 2 workers for each machine. Saving staff wage and management cost therefore.
6. Meet highly hygienic standard. Full electric driven machine is more suitable for the application of food, beverage, medicine etc. which has strict hygienic requirement.

7.Utility model patents and know how is applying to this machine.

product feature
1. Equip with servo motor to drive die-head, blow pin and carriage movement.
2. SIEMENS S7-200 PLC, response speed is 0.37μs
3. Blow pin adjust by setting parameters from the touch screen, free from mechanical adjusting.
4.  Replace mechanical structure of hydraulic cylinder and sensor with servo motor and ball screw rod, providing accurate action, quick movement and fast responding.
5. Incorporate with electric lift platform and deflash device.
6. Use famous pneumatic, hydraulic and electrical control element with long life usage.
7. Optionally configurate with automatic material loading machine and product conveyor to meet flow line production.
8. Extruder uses variable frequency control which adapt to the change of extruder rotation speed in blowing process.
