EPET06-6H 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.


1. EPET06-6H high speed stretching blowing machine adopts energy saving servo control that not only could accomplish high-speed mold open/close but also save 30% energy compare to the same kinds of machines made by other manufacturers.
2. The mold clamping employs three-plate self-locking during which the mold is fast clamped at first and then get slow with increasing clamping force.
3. Heating box structure is designed at 6 adjusted zone, fulfilling different heating requirements for different tube length.
4. This high speed stretching blowing machine is with stable pneumatic system, which makes the buffer device work smoothly without loud noise.
5. It is controlled by all electric servo motor, which can avoid the leakage of hydraulic oil and thus contamination of the product.
6. It is with 6 cavities and the maximum blow volume is 0.6 L.
7. These machines have a unique design according to the effect on the PET material. Multiple blowing steps reduce PET residual stress.
8. Hot fill PET bottles made by this high speed stretching blowing machine are able to stand high temperatures ranging from 82°C to 95°C without deformation. This is an incredible success in the hot fill beverage domain.
9. It is operated by user-friendly PLC system.
10. Molding change is fast and simple.
11. Preform positioning is by servo-motor technology.
12. It is ideal machine for medium output production needs.
