Let us first understand phenomenon of blow molding.

Different types of plastics are manufactured differently. But let us consider the general process. The plastic is melted and the substance which is carried by melting is latched in the mold. Then the air is blown into it. After this, the plastic is allowed to cool down. Simultaneously, the plastic gets hardened. The mold gets unlatched and the inner part is ejected.

There are basically three types of blow moulding i.e. extrusion blow moulding , injection blow moulding , and injection stretch blow moulding.

The plastic is allowed to cool down. By cooling down, simultaneously the plastic is hardened, the mold opens and plastic is ejected.

Importance & Applications of Blow Molding Screw Barrel:

In the entire process, the screw barrel works as a heart of the machine. Therefore, blow moulding screw barrel is used in every plastic making factories. They are generally used in the machinery to create hollow plastics such as injection blow molding machine, rubber extrusion machine, plastic processing machine and PVC film making plant.
