Extrusion Blow Moulding Machine
Extrusion Blow Moulding Machine is a specialized industrial equipment used for producing hollow plastic parts through a process called extrusion blow molding. This machine is widely used in the manufacturing of plastic bottles, containers, drums, and other hollow objects. The process involves extruding a tube of molten plastic (known as a parison), inflating it inside a mold using compressed air, and then cooling and solidifying the molded shape.
- Extrusion System: The machine begins with the extrusion of a molten tube of plastic, which is known as the parison. The extruder melts the plastic resin and forces it through a die to form the parison. The parison is then clamped into a mold.
- Blow Molding: Once the parison is positioned in the mold, compressed air is blown into it to inflate the parison to the desired shape of the mold. This process creates hollow parts like bottles, containers, and other plastic products.
- Cooling: After the parison is inflated and takes the shape of the mold, it is cooled to solidify the plastic. This can be achieved by air or water cooling methods depending on the design of the machine.
