Czech Republic-based Gottschol Alcuilux CZ (GACZ) has revealed at Tire Technology Expo that it is set to top a record 2015 by further increasing its output of tire mould sipes and spring vents in 2016, by 30% and 20% respectively. In a further development, some of the production of springs for the vents will be brought in-house for the first time, initially to increase the flexibility for small-batch runs for R&D use.

“We are very satisfied with the show,” said managing director, Frantisek Vitek, “We’ve been coming to Tire Technology Expo for 10 years, so we were very familiar with Cologne, but we think the new hall is better, and the location and its infrastructure are more convenient for exhibitors and visitors.”

GACZ has also revealed a new product at this year’s expo, a spring vent to replace the normal mini-vents in tire sidewall applications. The associated rubber ‘pins’ in the sidewall have been known to interfere with the sensors used in the latest automated parking functions on new vehicles, a problem eliminated by the use of spring vents in a difficult-to-manage area of the mould. Vitek said that samples of the new sidewall vents are now with customers for trials.

Tire Technology Expo runs until Thursday, 18 February in Halls 19 & 20 at the Deutsche Messe, Hannover, Germany. For more information or to register for a free exhibition pass, go to
