Blow Molding

Parts made up of blow molding are hollow, and thin-walled, like bottles and containers that are available during a sort of shapes and sizes. Blow molded parts are often formed from a spread of thermoplastic materials. 

As mentioned above, there are different methods wont to form the parison which distinguish the subsequent three sorts of blow molding:

Extrusion blow molding – The parison is extruded vertically between the 2 open mold halves, in order that they can close on the parison and blow pin. This is often the foremost common sort of blow molding and is employed to manufacture large quantities of relatively simple parts.

Injection blow molding – The molten plastic is injection molded around a core inside a parison mold to make the hollow parison. This is often the smallest amount commonly used method due to the lower production rate, but is capable of forming more complicated parts with higher accuracy. Injection blow molding is usually preferred for little , complex bottles, like those in medical applications.

Stretch blow molding – The parison is made within the same way as injection blow molding. However, once transferred to the blow mold, it’s heated and stretched downward by the core before being inflated. This stretching provides greater strength to the plastic. Stretch blow molding is usually wont to create parts that has got to withstand some internal pressure or be very durable, like soda bottles.
