Midwest Molding is specialized in insert and composite molding, straight molding, and assembly. In many cases, due to the geometry or size of the inserts, we utilize pre-mold, over-mold, and continuous strip molding. MMI uses all state-of-the-art equipment in its manufacturing processes. All molding machines have closed loop systems from the container to the throat of the machine in order to safeguard any exposure from the outside environment. In addition, MMI provides JIT service to all customers and all personnel are cross-trained to perform various jobs.
