Challenge
As fuel economy standards and vehicle mass targets became a key deliverable for automotive manufacturers, MAP was faced with the challenge of designing a transmission case featuring premium acoustic and thermal performance. At the time development started, costly and heavy metal heat shields were in use. Seeing transmission area temperatures up to 250 C, a product needed to be developed that deadened sound frequencies from 500 Hz to 4,000 Hz.
Solution
To meet all performance and cost deliverables, MAP designed a part made with a moldable glass fiber substrate containing an EVA septum and aluminum foil face. After joint testing with General Motors, including dyno evaluation, a successful part design was settled to achieve heat resistance, acoustic absorption and durablility – all in one package.
Outcome
With a finalized design being assigned to future model year vehicles, MAP assisted with all aspects of the project from R&D lab work to material recommendations to designing the end product’s fastening methods. MAP’s vertical integration in CNC tooling allows for a quick product release to the market place.
