Blow Moulding Process
Main Features
1. Outstanding pneumatic system design and buffering device makes the machine running smoothly with low noise;
2. High quality pneumatic and electric components enhance machine's reliability and low maintenance;
3. Front open clamping is good for easy operating and mold changing;
4. Infrared preheater equipped with frequency converter for higher accuracy heat distribution for the preforms;
5. Pre-blowing helps to have better PET bottle blowing formation;
6. With blow cost and flexbility,this machine is extremely ideal for special bottle makers to have variety bottles and jars.

1.The production capacity depends on preform weight thickness & bottle shape, and the worker's operating speed.
2. If you want to increase capacity of semi-automatic blow machine, we recommend you use 2 sets of preheaters
for one main blower.
3. If it is required, we can also supply you the auxiliary equpments(such as blow mould, air compressor, front&rear filter etc.) .
4. Specifications will be changed when the machine improved without prior notice.
