How Blow Molding Screw Barrel is used in Blow Molding Machine

1 Jan


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.
