Mold cooling is a key process to cope with current market demands including production speed, flexibility, quality and lightweighting. A predictable and efficient cooling system is a must to accomplish a good container quality and an elevated production speed. Such a high efficiency (energy waste) cooling offers also more production flexibility, especially as far as special shapes are concerned. The available service tool TekPak calculates the 3D mold glass contact temperatures and ensures predictability based on mold and process parameters. In addition, a successfull cooling system has to serve different needs on the blank and blow sides.

Blank side cooling and blow side cooling

Blank Side

The final container glass distribution is primarily set by the blank mold temperature profile and the resulting parison quality. Therefore a predictable, adjustable and stable blank mold temperature grid is vital to achieve a high container quality. The blank cooling is in fact a parison conditioning system.


  • Efficient cooling air utilization = energy savings
  • More constant potential predictable mold temperature
  • Production speed increase
  • Less job-change and production downtime
  • Noise reduction


  • Higher cooling efficiency -> Speed increase potential
  • Individual cooling of molds -> Optimized cooling conditions
  • Fumes and heat carried away -> Improved operator environment
  • Easier mold change -> Reduced downtime

Blow Side

On the blow side, cooling leads to the stability of the container. This stability defines the production speed. The cooling capacity has to be predictable and high. It is also important to use cooling wind as efficiently as possible and not to waste energy.
