Spencer Plastics is a custom injection molder located in Cadillac, Michigan. Founded in Mesick, Michigan in 1998, to try out tools for mold maker, Mesick Mold, Spencer Plastics purchased a 150-Ton Niigata injection molding machine and at the request of Mesick Mold customers, began running parts at high production volumes.

Spencer Plastics Incorporated is now a supplier of high quality engineered products for the automotive, recreational, and custom manufacturing industries. SPI currently has 35, 110, 150, 200, 310 and 385 ton press capabilities. SPI also offers services for rapid prototyping, concept development, assembly, and mold tryouts.

With the tooling experience, engineering knowledge, and state of the art production equipment, you can rest assured that any molds being run at Spencer Plastics will be well designed, manufactured, and maintained. Any issues with molds are addressed quickly, as SPI is not dependent on an outside tool shop.

Spencer Plastics focuses on customer satisfaction and continuous improvement through service, quality, and cost-saving manufacturing opportunities. We strive to give our customers personal service by going beyond what is expected to produce quality parts on time. We look forward to working with you and your future manufacturing needs.
