Blow Molding

Industrial Blow Molding

Thermoplastic melt is prepaered in the extruder and forms the parison (molten tube) through the head. The mold (consisting of two halves) is closed around the parison. High-pressure gas inflates the parison against the cooled walls of the mold, forming the parts shape.

Shuttle Method Blow Molding

When a continuously extruded parison has reached a certain length, the mold is closed and the parison is cut off with the cutter. The mold is then calibrated to enable the air to be blown in to form the parts shape.

Shuttle Method Blow Molding

Rotary Method Blow Molding

Several to dozens of molds are clamped to a rotating wheel, which revolves to enable the parison to be supplied into each mold in a continuous sequence. The mold is closed and air is blown in to form the parts shape.
