What is the process of blow moulding?The process of extrusion blow molding generally includes 6 steps. Hollow blow molding machine is a kind of extrusion or injection molding of thermoplastic resin or plastic, and then obtain the tubular plastic parison, which is placed in the split mold after being heated to a softened state. After the mold closing mechanism drives the mold to close, immediately Compressed air is passed into the parison to inflate the plastic parison and adhere to the inner wall of the mold. After cooling, the mold is released to make various hollow products.
