Philosophy and Principles
Tooling & Equipment International (TEI) is a vertically integrated manufacturer specializing in prototype and low-volume aluminum castings and precision-machined components for a wide variety of industries.
Utilizing advanced CAD/CAM technologies, 3D sand printing, low-pressure casting, CNC machining, heat treatment and inspection technologies, TEI manufactures complex components to customer-provided product requirements and specifications.
TEI’s engineering activities support our internal manufacturing processes and include casting simulation, mold and core development, CNC programming, machining simulation and the development of internal tooling and production aids required to manufacture customer-defined products. TEI does not provide design and development of customer products.
Our vertically integrated capabilities include manufacturing engineering, casting, machining, heat treatment and inspection on one site, providing our customers with advantages in timing, confidentiality and quality.
TEI is committed to customer service and satisfaction. People are our most important assets. Our employees have extensive experience; many have worked for decades within the company and industry. This wealth of experience is reflected within our products and heritage.

History
TEI can be traced back almost one century to the founding of Automotive Pattern in 1918. As the company expanded, Automotive Pattern outgrew its foundation and in 1983, evolved into Tooling & Equipment International, a dynamic organization with a firm global outreach.
By 1998, the demand for its products moved TEI into its current home, an 83,000 sq. ft. state-of-the-art facility, located in Livonia, Michigan. That same year, TEI incorporated the Casting Development Center, capable of rapidly producing low volume, low pressure castings in most aluminum alloys, while also providing a tool testing service, and most recently in house heat treating.
In 2001 business diversified into Military and non-automotive castings and machining. Today, TEI specializes in prototype and low-volume aluminum castings and precision-machined components, supported by advanced manufacturing, engineering and inspection capabilities.
