With regard to moulds and plungers for new containers, Heye works together closely with its sister company UniMould, which has considerable long-term experience in the manufacture of NNPB/PB plungers, plugs and cooling tubes.
Several years ago, UniMould developed a special and well-proven plunger coating. Together with the high quality mould and plunger material, this coating optimizes the impact and internal pressure condition of the container. Damage to a container’s internal surface is avoided by this special plunger material and coating combination.
Based at Obernkirchen, Germany, UniMould GmbH has over 60 years’ experience in the production of accessories for the glass packaging industry.
The company delivers quality and service that exceed customer expectations, in a market where quality standards are constantly raised and surpassed. UniMould continually invests in the latest machine tool technology to deliver the highest quality components possible, on time and at a competitive price. This commitment is mirrored by the company motto: ‘Passion for perfection in glass’.
Customers benefit from this ‘one-stop’ service and co-operation, generating a wide diversity of valuable experience.
