Blowing Mold Basic Process 

1. A thermoplastic resin is heated to a molten state 

2.It is then extruded through a die head to form a hollow tube called a parison. 

3.The parison is dropped between two mold halves, which close around it. 

4.The parison is inflated. 

5.The plastic solidifies as it is cooled inside the mold. 

6.The mold opens and the finished component is removed.
