I  Extrusion blow molding machine

Extrusion blow molding machine is a combination of extruder and blow molding machine and composite mold organization, which is composed of extruder and mold head, blowing equipment, mold organization, thickness control system of mold blank and transmission organization. Billet die head is one of the important parts to decide the quality of blow molding products, generally has a side feed die head and a center feed die head. The storage cylinder type blank die head is used for blow molding of large products.

II  Injection blow molding machine

Injection blow molding machine structure is mainly composed of raw material plasticizing injection part, closing part, rotary table, release device, mold, auxiliary device and control system and so on. The work flow will be according to the product molding material formula requirements, the mix of uniform raw materials into the molding machine.

After entering the barrel, the raw material is fused, the screw moves forward, the molten material is injected into the mold cavity of the mandrel, the mold is cooled, and then the model blank is blown to the lower half of the mold cavity of the working position, and the mold is clamped, and the compressed air is blown through the center hole of the mandrel, and the type embryo is blown close to the cavity wall, becoming the product shape, becoming the product shape, after cooling the mold; Then the rod rotates 120° to the demoulding station with the product, and the product is pushed out from the mandrel to complete the procedures of plasticizing, injection molding, blowing molding, cooling and demoulding of raw materials for product production.

The above is all about the different structure of the blow molding machine. I hope this article will be useful to you.
