Used Uniloy-Springfield Foam Injection Molding Machines for Sale

The Springfield structural foam machinery line traces its origins to Springfield Cast Products of Springfield, Massachusetts, which in 1969 is credited with building the first commercial horizontal press designed expressly for structural foam molding. The business passed through several ownership changes over the following decades, including acquisition by Johnson Controls in 1985, before becoming part of the Milacron Plastics Technology Group in 1998 under the Uniloy Milacron name. The structural foam division operated out of Tecumseh, Michigan during the Milacron years, and the Springfield brand name remained closely associated with the product line throughout.

The flagship product line is the SF series of low-pressure structural foam injection molding machines, offered in a range of clamping forces from roughly 300 to 2000 tons. Models such as the SF 300, SF 350, SF 500, SF 750, SF 1000, and SF 2000 are horizontal hydraulic machines built around large-platen, multi-nozzle clamp designs that allow processors to run very high shot weights — often 100 to 300 pounds or more per cycle — in materials including HDPE, polypropylene, ABS, and polystyrene. Wide-platen configurations and multi-nozzle extruder arrangements let a single press mold multiple large parts simultaneously, dramatically improving output per cycle.

Uniloy-Springfield structural foam machines serve a broad range of end markets that demand large, rigid, lightweight thermoplastic parts. Core industries include material handling (pallets, bulk bins, collapsible containers, totes), infrastructure and utilities (underground enclosures, vaults, conduit systems), lawn and garden products, janitorial and storage equipment, and industrial housings and cabinetry. The automotive supply chain has long relied on structural foam presses for returnable dunnage and component-transport containers.

Buyers seeking used Uniloy-Springfield structural foam machines are drawn by the line's reputation for heavy-duty construction, long service life, and the relative simplicity of the hydraulic clamp and extruder systems, which keep maintenance costs manageable. Because structural foam operates at low injection pressure, tooling wear is minimal and molds often outlast multiple machine generations. Parts and service support for the SF series have remained available through Uniloy and third-party suppliers, and the machines hold their value well on the secondary market — making a used Uniloy-Springfield press one of the most cost-effective paths into large-part structural foam production.
