1) What is blow molding?

Many of the pieces that form our plastic carrying cases are made with blow molding. Blow molding is a process by which we manufacture hollowed, plastic parts that we use to create our cases. You will find three different kinds of blow molding:

The process used to make the cases is extrusion blow molding. The plastic is melted down and is formed it into a parison or preformed piece. A parison is a piece of plastic formed into a tube that has a hole on one end to allow compressed air to pass through. The parison will then be clamped into a mold where air will be blown into it to form the case, or the plastic pieces for the case. When the plastic is cool and has hardened, the piece will be pulled from the parison and the process starts again. 

2) How does blow molding differ from other plastic molding processes?

Blow molding is exclusively used to make hollow parts that make excellent plastic carrying cases. Other kinds of blow molding are used to form solid pieces that are useful on their own. These plastic pieces may include plastic utensils, the handle of a plastic cup, or other items.
