Origination of the RTM Process

Osborne developed a new closed-mold molding process in 1976, later known in the plastics industry as Resin Transfer Molding (RTM). The RTM process involves mixing a liquid resin with a liquid catalyst (hardener) and injecting the material into a closed mold that contains a fiberglass preform. The fast reaction time and ability to tailor materials to meet a wide variety of physical properties like abrasion or flame resistance, quickly propelled RTM to a well-known molding technique.

With the acquisition of Westco Tool & Die, Osborne expanded its metal fabrication capabilities.
