Injection molding machines are typically used for injection molding, which involves injecting molten material into a mold cavity to create a shaped part. Blow molding, on the other hand, is a different process used to create hollow objects such as bottles and containers.
For blow molding, you would typically use a blow molding machine, which can be of several types, including extrusion blow molding machines and injection blow molding machines.
Extrusion blow molding involves extruding a tube of molten plastic, then "blowing" it into a mold to form the desired shape. Injection blow molding combines injection molding and blow molding. It starts with injection molding a preform, which is then transferred to a blow molding station to be inflated and formed into the final shape.
