Sell PET Preform Injection Molding Machine

Machine features:

Injection unit:
1. Advanced design in injection unit
2. High flexibility to match and change various diameter screws
3. Diagonal layout of carriage cylinder to ensure balance support
4. Guide rods and support frame used for carriage support, 1/3 of weight is reduced
5. Screw and barrel are made of high quality materials, improves their working life
6. Anti-wear bushes are replaced by copper bushes, which improves lubrication result
7. Two-stage metering speed and back pressure setting.

Hydraulic unit:
1. Bosch/Frexroth proportional pressures valve and flow valve fitted in our machines
improve the control precision
2. Adoption of vane pump which matches with proportional flow valve and pressure
vale, increase the control precision
3. Individual pressure valve adjusts the range of pressure, enhancing the control
precision
4. The hydraulic parts and seals are from famous international manufacturers

Control unit:
1. Japan made computer controller specially designed for injection moulding machine
2. High reliability and precision international electronic components are used
3. Automatic mould height adjustment
4. Screw rotary speed control
5. High speed image processor with curve display
6. Memory storage for 120 sets of mould data
7. Four transducers and one set pressure sensor
8. Screen saver will lengthen the life of life if display screen
9. PID closed-loop temperature control, temperature setting range between 0 to 399
degrees

Clamping unit:
1. Compact space saving toggle mechanism design
2. Finite element analysis ensures all platens key structural components for their
maximum service life and best moulding results
3. Advanced stress analysis software are applied in design of tie bars and screw
4. Stable mould closing, opening and adjustment
5. Enlarge tie bar distance and mould opening stroke providing flexibility in using
larger mould
6. Enlarge cylinder plate together with movable platen forms a single piece of casting.
This improves rigidity of both ejector cylinder support and platens
7. Enlarged ejector stroke and robustness if cylinder support specific for long hollow
plastic parts
