Minneapolis based Steinwall, Inc. is a precision custom thermoplastic injection molder with a reputation for handling tight tolerance, high cosmetic, custom molds and using engineering grade resins. Our customers include Fortune 500 companies as well as startup firms.
Our engineering personnel and equipment capabilities are focused on partnering with our customers in strategic alliances. Our in-house tool room provides expert input during tool design as well as corrective action on inherited tooling.
Our molding facility is unique to the molding industry. We enclosed the molding area, creating a white room environment. Temperature and humidity are maintained at constant levels to ensure high quality production.
With our addition of a distribution wing, Steinwall now provides inventory management. Combining this sought-after supplier managed function has given us an advantage among our competitors – allowing us to be a full-service manufacturer.
