[0002] Blow molding refers to the process of extruding or injecting a thermoplastic resin into a tubular plastic preform, which is placed in a split mold while hot. After the mold is closed, compressed air is introduced into the preform to inflate the plastic preform and cling to the inner wall of the mold. After cooling and demolding, various hollow products are obtained. Blow molding requires the use of a PE film blow molding machine.

In this regard, we propose a PE film blow molding machine to solve the above problem. Utility Model Content
