With the increase in demand for plastic products, the development of hollow blow molding equipment is expanding, and the mold and closing mechanism in hollow blow molding equipment is an essential key part of blow molding machinery, this article will take you to understand the evaporator of blow molding equipment.
Hollow blow molding machine is a thermoplastic resin or plastic extrusion or injection molding, and then get a tubular plastic billet, in the heating to the softening state placed in the split mold, the mold closing mechanism drives the mold to close the mold, immediately through the compressed air in the billet, so that the plastic billet blow and close to the mold wall, after cooling demoulding, so as to make a variety of hollow products machine
The process of extrusion blow molding generally includes the following 6 steps:
1, the extruder melts the plastic raw materials, and the melt transported to the head is shaped into a tubular blank.
2, after the billet is transmitted to the set length, the closing mechanism makes the blow mold close, and the plastic billet is sandwiched between the two half molds.
3. The compressed air is injected into the plastic billet through the blow hole, and the billet is blown to make it close to the mold cavity.
4. Forming and waiting for cooling.
5. Open the mold and take out the cooled product
6, modified products, while recycling side waste reuse.
