A Clear Focus.
Delivering a difference
Since 1972
Like other Tier 1 suppliers, MPC provides thermoplastic components and assemblies to the automotive industry. But that’s where the similarities end.
Where others claim to be experts in everything, we focus. Every facet of our organization has been meticulously designed, aligned and optimized for one purpose: to provide superior production capabilities to major automotive OEMs. From the practical, reliable design of our parts to the depth of our offerings to our singularly-focused manufacturing processes, execution excellence is the driving force behind everything we do. It’s why we’re able to make such a difference for the major automotive OEMs we serve.
"Every day we work together to solve challenges, add value, and deliver world class products and services. Knowing our customers have lots of choices, we strive to deliver more. We want to be your supplier of choice!"
Our Legacy
A History of Exceeding Expectations
Founded in March of 1972 by the Brost family in Jay Brost’s garage, we got off to a fast start in the first year by developing, patenting and manufacturing an automotive check valve for the Ford Motor Company.
Since then, major automotive OEMs have trusted MPC to deliver in ways that make a difference in the marketplace. And the same entrepreneurial spirit that inspired Jay Brost more than 40 years ago is still alive and well and shared by each one of our nearly 1,500 employees.
Focused on building a better business.
MPC leads the industry with its ability to improvise and rally around critical customer needs and time constraints whether designing, manufacturing or both.
The responsiveness of a family-owned business coupled with the muscle of a global player makes MPC unique in our ability to follow through. Combine that with our location in America’s Heartland, and you have a company that will work hand-in-hand with you to deliver goods quickly and at low cost.
