Extrusion blow molding machine types

Extrusion blow molding machine types.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 Automatic blow molding equipment 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 extrusion blow molding machine types.

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 an especially 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.

Blow Molding Machine superiority

1.Double stations and linear movement, high intensity stainless steel mould platens, driven by hydraulic pressure, designed and analyzed by finite element aided software, ensure big clamping force, no expansion of mold.

2.Specially designed screw with high L/D ratio insures good plasticizing and stable extrusion; high precision and no part line die head guarantees customers’ top-quality requirement.

3.Famous brand of vector inverter in high pulling torque, complied with special extrusion hardened reducer, can operate in stable, durable, and low noise state.

Plastic extrusion blow molding machine features:

Used in chemical, petroleum, food, lighting, tools, automobiles, motorcycles, toys and other fields, used to blow plastic barrels, chemical barrels, auto parts (water tank, fuel tank, air conditioning outlet duct, car tail), toys (wheels) , hollow motorcycles, basketball hoops, children’s castles), tool bags, dust collector pipes, stadiums and bus seats, etc.
