Sep 19, 2018

Extrusion blow molding is one of the main methods of manufacturing hollow thermoplastic parts, so the blow molding toolbox is also made by this process. The blow molding kit material is high density polyethylene. Depending on the application, styrene polymers, polyvinyl chloride, polyester, polyurethane, polycarbonate and other thermoplastics can also be blow molded.


Blow molding kits are manufactured by extrusion blow molding, which forces the material through a hole or die to make the product. The extrusion blow molding process of the blow molding toolbox consists of the following steps: first, the extrusion of the plastic preform, that is, the hollow plastic tube; then, the closure mold is closed on the parison, the mold is clamped and the parison is cut. .


What is to be done next is to inflate the cold wall of the cavity, adjust the opening and maintain a certain pressure during cooling, open the mold, remove the blown parts; finally, after finishing the flash, the blow molding tool is finished. , the container used for tool saving.
