Sabic’s high-temperature Ultem 1000 resin has been chosen by Vitality Foodservice, a manufacturer of drinks machines, to create a low-dose steam heating ‘bump pump’ for its latest coffee dispensing system.

The high processing temperature, stiffness and dimensional stability of Ultem resin, combined with a new, highly efficient two-shot injection moulding process helped Vitality achieve part consolidation, reduce cycle times and improve overall production efficiencies, according to Sabic.

“We are very pleased with the results of this project, which was a success largely because of Ultem resin’s high performance and the efficiencies of two-shot moulding,” said Rick Baron, director of engineering, Vitality Foodservice.

“We were able to reduce cycle time by two thirds and significantly boost our productivity, both particularly important in the current economic environment. Also key was development time – Sabic helped us realize a speed-to-market advantage in a competitive industry.

To create the two-part bump pump, Vitality’s moulder, Dymotek, uses two-shot injection moulding, and exposes the Ultem resin to UV light before overmoulding to enhance adhesion of the silicone component.
