There are several different ways plastics can be molded into the shape of a desired product. Injection molding is one. Other types include rotational, extrusion and compression molding. Yet when it comes to plastic bottle suppliers, one of the more favored types is blow molding.


What is Blow Molding?


Blow molding is a form of creating a specific product shape. To an extent, blow molding is similar to glass blowing. It is also comparable in its procedure to injection and extrusion plastic molding. In essence the steps are basic.


* Feed raw plastic pellets, powder or beds into an extruder or revolving chamber to be heated until it melts


* After the plastic is melted – usually into a tube form, it is forced into a chilled mold by compressed air


* The force of the air going through this tube-shaped object makes the plastic assume this shape


* After cooling, the plastic is ejected out of the mold


Advantages of Blow Molding


Blow molding has some advantages over other types of molding, particularly for plastic bottle suppliers. Molds are less expensive using this means. Continually improving materials resulting in superior structural integrity have resulted in a preference for this type of molding process in certain industries. In fact, blow molding has begun to replace more traditional approaches to plastic molding.


What is Blow Molding Best Suited for?


Yet, blow molding does have specific purposes. It is best for manufacturing hollow products. It replicates these hollow one-piece shapes or items easily. It can do so at high volumes with uniform quality. This is why plastic bottle suppliers are fond of electing this type of plastic mold production over others.
