Blow molding can be defined as a special manufacturing technique that employs air pressure to create hollow plastic parts The air pressure is blowing into the hollow part just like the process of blowing air into a piece of balloon The blow molding process starts with heating a plastic to appropriate temperatures so it will become pliable and easy to work with It is further heated till it becomes semi liquid After this, the pliable tube is inserted into a die and compressed air is injected just like a balloon It now sets the die in the desired shape After cooling down, the product is removed. The walls of the mold in many blow molded parts have a consistent and equal thickness throughout the mold which enhances the overall durability of the product.
