EPET1.5-4H Stretch Blow Molding Machine

Leshan PET stretch blow molding machine is used to blow various shapes of bottles for containing chemicals, cosmetics, pesticide, etc. Our all-electric PET blowing machines can be divided into cold-filling and hot-filling series. Adopting energy-saving servo control, it can keep high-speed mold clamping while saving 30% energy comparing to the same kind of machines made by other automatic blowing equipment manufacturers.


Ideal solutions for medium output production needs.
1. EPET1.5-4H injection molding machine is operated user-friendly PLC system.
2. Molding change is fast.
3. Preform positioning is performed by servo motor.
4. This machine is ideal choice for medium output production needs.
5. Energy saving servo control is adopted not only to accomplish high-speed mold open/close but also to save 30% energy compare to similar machines manufactured by other factories.
6. This injection molding machine is adopts three-plates self locking to ensure fast clamping and strong claming force.
7. The heating box structure is designed at 6 adjusted zone, meeting different heating requirements for different tube length.
8. With stable pneumatic system, its buffer device works well and smoothly, without generating load noise.
9. It is controlled by all electric servo motor, avoiding the hydraulic oil leakage and contamination of the product.
10. It has 4 cavities and the maximum blow volume is 1.5 L.
