Automotive Micro Molding

As the demand for more advanced technology grows in the automotive world so does the pressure on microtechnology. On-board systems for everything from autonomous driving to cabin comfort employ a wide variety of microelectronics, sensors, and other small components. Most engineers expect these added technologies to be discreet, robust, and cost-effective. Automotive micro molding is one enabling process that can help engineers achieve all three expectations.

The Process

LCP Liquid Crystal Polymer - micro molding materials

LCP Liquid Crystal Polymer

Supplying to the automotive industry requires a very rigorous manufacturing process. Any company supplying complex components, especially a micro molder, must have the proper quality systems in place but it goes beyond that. The right partners must focus on scalability and sustainability to manufacture such critical components for years to come. Components for automotive systems don’t change often and have no tolerance for supply chain disruptions.

Common materials and examples

Each industry has it’s own go-to materials like ABS, PCPMMA, and LCP, but we also deal with a large share of OEMs and manufacturers that require innovative new materials as well.

Common component examples of automotive micro molding are sensor housings, illumination optics, connectors, electronic sub-components, and battery seals.

Our largest automotive micro molding component to date is a power-steering sensor housing.

Three Important Aspects of Automotive Micro Molding

  1. The earlier in the design process the conversations can begin the better. Often what engineers think is impossible, we’ve already proven.
  2. The DFM (Design for Manufacturability) process must be thorough.
  3. It’s vital to understand the total cost of ownership when comparing prices and doing your research.
