Injection Molding Services

We build all customer injection molds in-house right here in Michigan. Our mold builds carry an unlimited tooling life warranty as long as we are running your production parts. All tooling is maintained by our plastic injection molding staff for the life of your project.

With complex or dimensionally critical parts our prototype capabilities can help you reduce design risks and limit your overall production costs. Before building an expensive multi-cavity mold for your long term production, we’ll build you a low cost injection mold and produce low volume production quantities for testing.
MSI Mold specializes in production quantities of 1,000 to 100,000 parts or assemblies per year. With every production injection molding project we collaborate closely with our customers on manufacturing feasibility and advanced quality planning (AQP) for reliable high quality production.

MSI Design & Engineering
Our CAD design services can help you bring a product concept to life. We can take your 2D drawings or sketches and create a 3D CAD model for use in rapid prototyping or production manufacturing. All part design advice or CAD model revisions are free to our customers.
We know that every project is different. So if your injection molding project requires extra’s such as assembly, special packaging, secondary machining, or pad printing we can help accommodate your needs.
