Plastic Molded Products Hollow Injection: Pipe

• 

  A part of gas-assist injection molding.
  A gas injection process is added to the conventional plastic injection molding process. During the process of pouring molten plastic into a tubular mold to cool and solidify, inert gas is filled to push out the inner molten portion to form a hollow.
  Although it is injection molded, the feature is that the inside is hollow. In addition to the tubular part, other shapes such as screw fixing parts can be integrally molded, which has the advantage of reducing weight.
