Thanks to Solvay’s MMI Technyl Design teams at Solvay Engineering Plastics, a global leader in polyamide materials and TrelleborgVibracoustic, a leader in automotive vibration control solutions have together created a faster and smarter way to design and develop thermoplastic engine mounts. 

“When designing high performance engine mounts it is essential to provide our customers with products which offer greater endurance coupled with less weight, therefore we are constantly looking for lighter materials, replacing metals with plastics,” explains Ludovic Chauvet, Engineering Expert at TrelleborgVibracoustic. “Our choice of utilizing MMI Technyl Design was determined by the quality of the material anisotropic data available for Technyl products. Building on the results, we developed a unique solution for designing and predicting the performance and manufacturing of structural components, while taking into account the production process,” he added. “Together with our FIAPLAST programme for mechanical dimensioning, this unique approach enabled us to decrease the mass of our customers’ engine mounts by 30 percent and reduce time to market.”

MMI Technyl Design is an advanced service Solvay Engineering Plastics offers customers to meet the light-weight challenge. This technological solution is allied with an extremely comprehensive materials database and allows for a wide range of calculations when integrated with injection process modeling. A powerful and high-performance solution allowing to accurately predict the performance of injection-molded parts made from Technyl materials and thereby significantly reduce the mass and cost of the applications, for which crash and fatigue resistance are key requirements.

The first applications developed by TrelleborgVibracoustic for engine mounts with significantly reduced mass were at Peugeot-Citroën for their 3-cylinder engines. Today, applications can also be found at Renault-Nissan on some Renault, Nissan and Dacia models. By 2016, TrelleborgVibracoustic will be producing several million thermoplastic engine mount components annually.
