About Gregstrom Corporation
Gregstrom Corporation makes custom rotationally molded plastic parts and assemblies. Its current rotomolding operation is in Bedford, New Hampshire, following the move from Woburn, Massachusetts announced in 2025. The company combines molding with design reviews, mold making, product assembly and testing, and advertises robotic trimming and foam filling as supporting operations. Applications include equipment housings, manifolds, bins and other hollow plastic components. Gregstrom’s thermoforming business merged with C&K Plastics in 2024; this listing focuses on Gregstrom’s continuing rotational-molding operation.
