Our products

Product category: Spare and wearing parts


Hunprenco has worked closely with glass container companies to develop material and production methods to assist the glass industry in its efforts for increased efficiency, reduction in downtime and improved enviroment friendly quality containers.
There has been a call to product lighter containers and the market is moving more towards the Narrow Neck Press and Blow (NNPB) forming process technology, which has increasingly become an alternative to the conventional Blow Blow production method. This NNPB production is helping customers to increase production speeds and save energy, while also improving returns on investment via the production of lighter containers.
Our plungers are manufactured with various coatings depending on customer preference, applied by state of the art technology ensuring a uniform dense coating.
Three tungsten/nickel coatings giving a hardness range of 56HRc to 62HRc
One tungsten/cobalt coating giving a hardness range of 59HRc to 63HRc combined with elevated working temperature characteristics.

Cooling Tubes

In 1999 Hunprenco started supplying cooling tubes to customers to the same standard and quality as the plungers. This developed into the cooler division.
Cooling tubes for both NNPB and Standard Press/Blow production are produced on CNC machines. Tube coolers are swaged to meet customer requirements for profile and accuracy, using swaging dies manufactured in-house to cover a wide range of tube sizes in both mild steel and stainless steel.
The swaging technique ensures a uniform wall thickness and maintains concentricity to give excellent base fit and assembly, also allowing the internal tip profile to smoothly follow the external tip profile to improve cooling air flow within the plunger.
In addition, an anti-rotation mechanism has been implemented to eliminate movement and enhance cooler performance.
All cooling tubes undergo inline inspection, as well as final inspection, which includes a water and airflow test for vent hole clearance. A certificate of conformity is issued with all goods dispatched.
