High-Speed Good Price Plastic Sea Ball HDPE Blow Molding Machine

High-Speed Good Price Plastic Sea Ball HDPE Blow Molding Machine. Including two types are the semi-auto blow molding machine and the auto blow molding machine.

The semi-automatic blow molding machine means that the finished product has excess material, which needs to be manually received and removed. It is relatively cheap and suitable for areas with relatively low labor costs; the fully automatic blow molding machine means that the machine can automatically remove the excess material, which is more convenient. It is also more expensive and suitable for areas with relatively high labor costs. This is the introduction of a High-Speed Good Price Plastic Sea Ball HDPE Blow Molding Machine.

This is the principle that all extrusion blow molding machine types are the same. In extrusion blow molding a plastic material feedstock is fed through a hopper onto a feeding transfer screw. This feeds material into a specially designed blow molding die that directs the material flow to create an extruded hollow tube called a parison. This parison drops with gravity until it is a process-specific length, which triggers the mold to close around it and seal the bottom edge (that gives the distinctive end seal). A cutting knife slices the open top of the parison and a blow pin moves to the top of the tool and inflates the parison against the walls of the tool cavity. The cooled tool walls solidify the molding and after a preset time it is ejected and the process repeats with the newly extruded parison.
