Blow molding machine
A thin gauge of molten plastic, called a parison, exits the die head ofthe extruder and drops vertically between the sides of the open mold. The parison has a high static charge and tends to bow and attrack towards the grounded metal mold. This results in quality failures in the blown bottles. When using multiple die heads the parisons carry a static charge of the same polarity causing them to repel each other, which often results in rejected parts. Heat resistant anti static bars assure elimination of static charges and no production failures and machine stops caused by the negative effects of static electricity.
