TPE shortens cycle time in the production of logo plates on engine covers

Mues Products & Moulds GmbH, based in Kolbermoor near Rosenheim, Germany, has put on the market a new type of logo plates for automotive engine covers. Cooperation partner for the development was Kraiburg TPE. The TPE compounder based in Waldkraiburg supplied the material for the soft component of the part. Hipex allows the production of the part in a 2K injection moulding process. Compared to a manual assembly of the hard and the soft component, this shortens the cycle time significantly and reduces the error rate.

New Santoprene TPV grades help the automotive industry meet new challenges

For 30 years Santoprene TPVs have been used to support the automotive industry building lighter-weight, higher-performance and more environmentally sustainable vehicles at lower system costs. The range of automotive applications includes weatherseals, interiors, exteriors, underhood and under car components. For semi-dynamic and static weatherseals, these TPVs provide durable sealing performance, lower weight, part function integration with simplified processing and long-lasting upgraded aesthetics. In interior skin applications, Santoprene TPVs deliver enhanced aesthetics, durability and “comfort touch”. Their durability, strength, sealing performance, temperature and chemical resistance of Santoprene TPVs make them a material of choice for underhood and under-car applications. ExxonMobil Chemical has recently introduced some new developments.
