PM Engineered Solutions adds Negri Bossi machine

04/15/2014

PM Engineered Solutions has added a Negri Bossi injection thermoset molding machine to its offerings. This acquisition allows PMES to expand its current thermoset capabilities, as well as continue to provide high-strength components through the Negri Bossi's manufacturing functions (25-363 ton, 22oz shot capacity shot-to-shot consistency, controlled process, repeatability).

The Negri Bossi is a custom thermoset plastic molder that uses a wide range of commercially available resins (granular phenolic materials, BMC, etc.) to create products that are heat resistant and electrical grade, and are glass reinforced as well.

Thermoset injection molding is a process that transforms granular material into molded shapes. During the molding cycle, thermoset plastics undergo an irreversible chemical reaction, or cure, brought on by heat, pressure and time. Once cured, it cannot be reshaped by melting and reprocessing. Cured thermosets have a highly cross-linked chemical structure which allows them to retain their mechanical and electrical properties as well as dimensional control over a wide temperature range.
