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.

About us

Company details

Where it all started...

Hunprenco was established in 1969 by Mr Eddie Neesom, who is Chairman and Managing Director. He started a small engineering workshop in a disused stable in the North Yorkshire village of Hunmanby on the east coast of England, as well as continuing his work as a Technical Steel Sales Representative.


In May 2009 the company was accredited with ISO 9001. This accreditation confirmed the company’s methodical procedures and high standards in supplying quality, service and reliability to all their customers.

Each component is checked at every stage, both dimensionally and visually, for any defects by the quality department. A final inspection is carried out using the latest computer-controlled coordinate measuring system, fibre optics to visually check internal profiles, and also check on surface finish.

Hunprenco’s policy is to give our customers a first class service at all times. Our dedicated, professional workforce and administration team work closely together to ensure total customer satisfaction. We also offer full sales and technical support and backup for complete peace of mind.
