Since Midwest Precision Molding (MPM Plastic)’s beginning, coil winding bobbins have been at the core of our business. Partnering with hundreds of manufacturers over the years has elevated us to “experts” in the realm of custom bobbins. The coil winding bobbins that we manufacture have been used in practically every application that calls for a plastic bobbin, including transformers, solenoids, relays, motors, fuel pumps, Switched Multimegabit Data Service, and many other electrical and electronic devices.
