Blow molding is a manufacturing process used to create hollow plastic parts by inflating a heated plastic tube, called a parison, inside a mold until it takes the desired shape. There are several types of blow molding machines, each designed for specific applications. In this article, we will discuss the most common types of blow molding machines.
types of 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 types of blow molding machine.
This is the principle that all types of blow molding machine 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.
1. The central shaft of the screw and the cylinder are made of 38CrMoAlA chromium, molybdenum and aluminum alloy treated with nitrogen, which has the advantages of high thickness, corrosion resistance and wear resistance.
2. The die head is chrome-plated, and the screw mandrel structure makes the discharge more even and smooth, and the blown film can be better completed. The complex blown film machine structure makes the output gas more uniform. The lifting unit adopts a square frame platform structure, and the height of the lifting frame can be automatically adjusted according to different technical requirements.
3. The unloading equipment adopts peeling rotating equipment and central rotating equipment, and uses torque motor to adjust the smoothness of the film, which is easy to operate.
