PTI Engineered Plastics is a custom injection molder and manufacturer of plastic components and assemblies. The customized 155,000 square foot facility in Macomb Michigan offers full design services, engineering, tooling, low and high volume production, and an array of secondary services.
PTI can take you from mind to manufacturing® starting with their industrial design and development studio PTI Design. PTI uses 3D CAD software and moldflow simulation tools to test and validate your product prior to manufacturing.
PTI’s Tool Room is home to the new Lumex Avance-25, the only machine in the world with the unique capability of manufacturing complex molds and parts in a single process. On the Tool Room floor you’ll find a fully integrated tooling network, (18) high-speed vertical machining centers, three of which are Makino with spindle speeds of 20,000 RPM’s complimented by a Makino Horizontal Machine. All machines utilize thermal shrink collet tooling for precision and accuracy. Their EDM department includes (4) high-speed graphite robotic load machining centers with spindle speeds up to 54,000 RPM. We offer plunge EDM machining as well as wire EDM capabilities. PTI uses an array of materials from aluminum, mild steel, hardened steels and stainless. Injection mold types include: unit-mold insert, free standing, shuttle loading, hot runner, single and multiple cavities.
Their production floor currently hosts (44) injection molding machines ranging from 12-750 tons of clamping force with .33 to 98 oz. shot capacity. Manufacturing capabilities include low and high volume production, insert/overmolding, high-temperature molding, contract manufacturing, assembly and packaging.
ISO Class 8 Cleanroom services include injection molding, assembly, secondary operations and packaging.
