Plastic Bottle Stretch Blow Molding Machinery

Blow molding Machine Introduction
Blow molding (or moulding) is a manufacturing process for forming hollow plastic parts. It is also used for forming glass bottles or other hollow shapes.
In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding.
The blow molding process begins with softening plastic by heating a preform or parison. The parison is a tube-like piece of plastic with a hole in one end through which compressed air can enter.
The plastic workpiece is then clamped into a mold and air is blown into it. The air pressure inflates the plastic which conforms to the mold. Once the plastic has cooled and hardened the mold opens and the part is ejected. Water channels within the mold assist cooling.
Blow molding machine can be used to produce a wide variety of materials, such as PE, PP, and PA.The largest capacity of the product is up to 10L. In accordance with different type of products, die heads can be changed to achieve multi-type production.
