High-speed Hybrid Electric Blow-molding Machine for PET Bottles
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.
9. Approach switch is from Swiss Contrinex which is excellent for security assurance.
