Semi-auto stretch blowing machine

Semi-auto stretch blowing machine is not so popular currently as the develop

With the rise of various automatic high-speed stretch blowing machine, semi-auto stretch blowing machine is not so popular as it was before. Since the semi-auto machine has its own limitation: low output and much labor work. Currently in this market only two types of manufacturers still use semi-auto stretch blowing machine. One is those starters and another is those producing some irregular bottle. For example, the water jug with handle. Till now, merely machine supplier is capable of making full auto machine for such handle jugs.

Buen semi auto pet stretch blowing machine has the capacity from 2L to 25L. The hourly output can reach to 350 bph to 1000bph. The bigger the bottle volume, the smaller the productivity. Semi auto machine has no auto loader and conveyor belt. It might needs some manual work for placing the preforms on machine. But the biggest advantage of such type machine is it’s high economy.

Figures of Buen semi automatic bottle blowing machine:

• Multiple styles and flexible choices
• Professional technical support
• Servo motor energy saving system and environment friendly
• World famous brand sare parts
• Satisfied after-sales service
