TrelleborgVibracoustic state that together with Solvay’s MMI Technyl Design, it has 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 utilising 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 TechnylDesign is a service Solvay Engineering Plastics offers customers to meet the light-weight challenge. This technological solution is allied with a materials database and allows for a wide range of calculations when integrated with injection process modelling. Solvay says this is a powerful and high-performance solution allowing to accurately predict the performance of injection-moulded 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. Nowadays, 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.
“For the past several years, our specialist teams and our advanced services such as MMI Technyl Design have been pushing the boundaries of metal replacement in the engine compartment,” says Peter Browning, Global Automotive Market Director at Solvay Engineering Plastics. “We are proud of our partnerships with automotive manufacturers and their suppliers being able to help them create value at each production phase from design through to industrialisation.”
