Injection Molding Services

At Midwest Plastics, we manufacture custom injection molded products for the aerospace, building, industrial, electronic, medical, maritime, and military markets, among many others. We operate injection molding presses in 55-ton to 1,600-ton range, giving us the capacity to mold small, large, and multi-component parts. With our injection molding capabilities, we work with an extensive selection of resins, and we produce parts in prototype, low volume, and high volume quantities.

Our versatile injection molding capabilities include various processes, such as in-mold assembly, which saves on secondary operations. Materials we work with range from general-purpose to engineering grade resins, such as ABS, acetal, PET, glass filled compounds, nylon, polyester, and polystyrene. We review design specifications, and with our material expertise, we can help select the materials with the ideal set of characteristics for optimizing manufacturability, quality, and service performance.

With the range presses available, we produce components using shot sizes anywhere in the 1.4-ounce to 365-ounce range. We have the technical capability to accurately fill molds with up to 64 cavities for multiple parts or part families. Our custom injection molding services are backed up by our strong engineering and in-house mold design-build capabilities.

We pay detailed attention to quality during every stage of production to ensure parts comply with specifications. Our process and products conform to ANSI, FAA, FDA, Mil-spec, SAE, UL, and other industry standards. We offer competitive pricing and personalized, proactive customer service.

Mold Process Type

High Press Tonnage – An Injection Molding Machine that exerts very high clamping forces. These machines are usually used to produce larger parts.
In-Mold Assembly (IMA) – Allows a metal insert to be embedded in a part in one operation for improved product structure and increased strength.
Solid – A process to manufacture solids parts that do not have any hollow cavities.
