Injection Molded Air Induction

Mid-States Rubber manufactured the air induction duct shown here for a customer in the automotive truck industry. Working with the customer specifications, we provided design guidance to optimize the manufacturability of this component to save on production and material cost. We recommended an injection molding process to form the intricate convolutes and ports with a high degree of uniformity and consistency, and designed and built the tooling required for its efficient manufacture. Meanwhile, in our in-house compounding and material test laboratory, our technicians developed a 75 durometer, Shore A hardness ethylene acrylic elastomer with the desired combination of properties to meet the performance characteristics of this application.

We molded this component, which features dimensions of 228.6 mm in length, 133.88 mm in width, and 165.1 mm in height, according to standard RMA A3 tolerances for commercial products. Our quality team used a variety of techniques to verify the material properties, and we assembled and shipped them to the customer. We manufactured 46,000 units within the defined 10-week timeframe.
