What is Plastic Extrusion Blow Moulding?

Plastic extrusion blow moulding is a manufacturing process that allows for the creation of hollow plastic parts. The technique combines extrusion and blowing to form these parts. Here’s how it works:

  1. Extrusion of Plastic Tube: Plastic resin is heated and extruded into a parison, which is a hollow tube of melted plastic.
  2. Moulding Process: The parison is then clamped into a mould.
  3. Inflation: Air is blown into the parison, causing it to expand and take the shape of the mould.
  4. Cooling and Solidification: Once it cools, the mould opens, and the finished product is ejected.
