Product Description

AIRMOULD® is the patented gas-assisted injection molding process developed by WITTMANN BATTENFELD. There are 2 variants: AIRMOULD® internal gas pressure and AIRMOULD CONTOUR® external gas pressure. The AIRMOULD® process offers the user major advantages especially with regard to a better surface finish and higher dimensional stability.

Advantages depending on the chosen process AIRMOULD® oder AIRMOULD CONTOUR® are:

  • Quality improvement
  • Avoidance of sink marks
  • Reduction of frozen tensions
  • Reduction / avoidance of deformation
  • Reduction of necessary clamping force
  • Reduction of cycle time
  • Reduction of weight
  • Design freedom


The modular AIRMOULD® system is suitable for gas-assisted injection molding with internal and external gas pressure.

Process steps AIRMOULD:

  • Melt injection into the cavity.
  • Injection of nitrogen into the melt either through the machine nozzle or through nozzles in the mold.
  • Complete filling of cavity.
  • Gas pressure is maintained until the part is sufficiently cooled and has reached dimensional stability.
  • Reduction of gas pressure prior to mold opening.

 

Process steps AIRMOULD CONTOUR:

  • Mold is completely filled with melt.
  • Injection of nitrogen between melt and cavity wall through special injection modules.
  • Throughout the cooling phase, gas pressure acts as holding pressure.
  • Gas pressure is released prior to mold opening.

 

Components AIRMOULD® systems:

  • Nitrogen generators: SE series, mobile units, store nitrogen filtered from the surrounding atmosphere through a multi-membrane system.
  • Pressure generator: DE series, nitrogen is compressed to an operating pressure of 300 bar.
  • Control and regulation: stationary or mobile electric control system combined with up to 8 pressure control modules or monomodules.
  • Gas injection: either together with plastic material through AIRMOULD® machine nozzles or via AIRMOULD CONTOUR® injection modules.
