OH-XCool® achieves tangible efficiency enhancement in the production of PET preforms. The in-house developments of Otto Hofstetter AG significantly improve the cooling of threads and support rings.

Mechanical components of injection moulds are exposed to very high strains. Otto Hofstetter AG has developed OH-Xtreme® to reduce mould wear substantially. OH-Xtreme® has been ensuring trouble-free operation and a long useful life of the injection moulds from Uznach for more than 10 years.

Otto Hofstetter AG started making moulds for PET preforms in 1977. The first order was placed by the Continental Can Company which had been commissioned by two major American beverage producers to evaluate a capable mould maker. Moulds for PET preforms are now a very important part of the business in Uznach. The technical specifications for preforms and production equipment have changed substantially.

The application of high-tech can pay dividends even in such simple things as flowerpots. A new approach reduces the consumption of raw material and minimizes the cycle time without impairing the high product quality. The novel technology has been developed by Soparco and Otto Hofstetter AG.

The Geneva-based luxury watch manufacturer Urwerk ranks among the most innovative manufacturers in Switzerland. Their creations combine handcraft skills that have been maintained across gener-ations with the possibilities afforded by leading-edge technology. It's a typical Swiss recipe that Otto Hofstetter AG is also committed to. And the latest example: the Cappello design for preforms.
