Bottle Blowing Machine

The Bottle Blowing Machine is a device for making plastic pellets into hollow containers by a blow molding process. Currently, the more common models include a one-piece hollow extrusion blower using PP and PE, which is formed by PET, PC or PP. The injection stretch blow molding machine, as well as the newly developed multi-layer hollow extrusion blow and stretch blow molding.
At present, most of the blow molding machines are still two-step blow molding machines, that is, the plastic raw materials must first be made into preforms and then blown. Currently commonly used in PET is environmentally friendly plastic.
Blow molding machine: After the liquid plastic is sprayed out, the wind is blown out by the machine, and the plastic body is blown to a cavity of a certain shape to make a product. This machine is called a blow molding machine. It is also a type of blow molding machine, namely a hydraulic blow molding machine.
The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is heated (or heated to a softened state) and placed in a split mold. Immediately after closing the mold, compressed air is introduced into the parison to blow the plastic parison. It is inflated and adhered to the inner wall of the mold, and is cooled and demolded to obtain various hollow products.
Steps
1. Place the preform in the preform container and automatically enter the preform positioning device via the delivery device.
2. The preform is automatically loaded onto the preform holder and then sent to the drying tunnel.
3. After heating, the preform is sent to the blowing platform, and then the mold is clamped. The pressure is pulled by low pressure, drawn by high pressure, exhausted, and finally opened.
4. The bottle is taken from the blowing platform by an automatic demoulding system.
