What MSI Mold Does
MSI Mold takes pride in being a trusted plastic injection molding company in Michigan. We deliver high-quality plastic injection molds and services, including prototype injection molding, production injection molding, and insert molding to clients across the U.S.
Our broad industry expertise, from agricultural to transportation, reinforces our capabilities to suit our plastic injection molding processes to meet customers’ specific needs in any industry.
Prototype Injection Molds

Taking a product idea from 2D drawings to 3D model renderings is a required part of the design process for injection molding. When a manufacturer creates a 3D model, they can use it for the prototyping process. While 3D-printed prototypes have gained popularity, plastic injection molding is a superior prototyping choice in most instances. This is because it helps gain real world insight into the product that will be manufactured in production.
MSI Mold specializes in prototype and production injection molding. Our prototype injection molds will help you identify and eliminate errors and reduce overall production costs. Call today to request a quote on this service!
Custom Injection Molds

While other injection molding companies in Michigan may outsource overseas, MSI Mold builds custom injection molds directly in-house. We use rapid tooling systems to create affordable injection molds at fast lead times, all without sacrificing quality.
3D Design Assistance

When you purchase your injection mold and custom parts from us, you can watch your design come to life through our free CAD design support services. Our team is capable of making 3D model renderings from simple 2D drawings, and can provide valuable part design and material selection assistance.

Unlike other injection mold companies in Michigan, MSI Mold can design, manufacture, and package these custom-molded parts in-house. We do not outsource any of our customer mold builds, and we specialize in production runs ranging from 100 to 100,000 units per order.
