Three kinds of blow molding machine

Posted by TINA at 19.03.2014

For blow molding machine area, three kinds of blow molding machine take over the market: injection blow molding, extrusion blow molding, and stretch blow molding.

Regularly, injection blow molding machine is for small bottles and container less than 500ml in volume. It is extremely accurate control of weight and neck finish. But the disadvantage is not in use for containers with handles and tooling costs are relatively high.

Extrusion blow molding machines are always to produce containers in 250ml or larger. Storgae box as large as 1040L weighing 120kg are ok; tooling is cheaper, and part proportions are not seriously limited.But it is with flash or scrap, in waste of resin. And it is more curcial for operator to control the part weight and quality.

Stretch blow molding machine is main used for bottle between 200ML to 2L, also it could be blow as large as 25L. The bottle is much stronger and it is allowed to reduce the weight.
