Hot runner systems: Innovative hot runner technology for superior quality and cost efficiency for injection moulding

Optimize your manufacturing processes while reducing your production costs with high-performance hot runner systems.

GÜNTHER is a leader in hot runner technology. We are synonymous with 35 years' expertise, maximum process reliability, perfect gate point quality and absolute precision, all excellently matched to your applications.


Reduce reject rate and production costs effectively: Improve your injection moulding processes thanks to pioneering hot runner technology

We use innovative hot runner technologies to develop modern, thermally insulated gate point systems. Our hot runners achieve highly efficient runner injection of molten plastic. Benefit from their significant advantages.


The advantages:

  • Material savings: The systems' high efficiency and the precise match to your requirements ensure enormous savings on expensive raw materials.
  • Up to 50% less energy: With the innovative BlueFlow® technology, you halve your energy consumption compared to conventional hot runner nozzles.
  • Homogeneous temperature management: Use GÜNTHER Hot Runner Technology to bring the temperature to exactly where it is needed and ensure a uniform high product quality.
  • Maximum time savings: Benefit from the simple installation geometries, minimum start-up times and reduced cycle times.
  • Lower reject rates: Perfect moulded parts with hot runner solutions which minimize your reject rate.
  • Optimum process reliability: With GÜNTHER, the entire injection moulding process becomes safer and more efficient.
  • Reduced space requirements: Smaller hot runner systems mean smaller injection moulding machines. Our patented, compact BlueFlow® hot runner nozzle allows you more space for different options.
