About West Michigan Plastics

West Michigan Plastics, Inc. was founded in 1986 and incorporated in 1991 in Holland, Michigan. The company began as a custom injection molder of engineered thermoplastic resins and has grown to operate a 16,250‑square‑foot facility in the same community. The shop specializes in high‑precision injection molding for engineered thermoplastics, supported by automated work cells that run 24 hours a day, seven days a week. Its equipment roster includes small, medium, and large presses, along with automated vision inspection systems and in‑cell data collection for statistical process control. The team also provides design optimization, material selection, tool construction, mold‑flow analysis, and applications engineering. Customers span automotive, government, medical, construction, furniture, agriculture, and electronics sectors. The company has held government contracts since the early 1990s and entered the medical market in 2002, building a diversified base that relies on its ability to deliver complex, high‑performance plastic components. Its stated differentiators include rapid turnaround from round‑the‑clock automation, a focus on highly engineered custom parts, and proactive collaboration on design, materials, and tooling to prevent defects.
