Spectrum Plastics Group (Alpharetta, Ga.) is expanding its specialty products and design engineering offerings through its acquisition of Apex Resource Technologies.

Financial terms of the deal were not disclosed in today’s announcement.

Apex has more than 60 people at its 45,000-square-foot facility in Pittsfield, Mass., and is a full-service design engineering, tooling and injection molding operation.

“Apex has all the elements we are looking for as we evolve our business to the next level,” Neil Shillingford said in a news release. “Great customer relationships, strong engineering and design capabilities, a focus on performance plastics suitable to invasive medical applications, and a solid operating culture that fits our core values.”

Private equity group AEA Investors recently acquired Spectrum – formed last year from the merger of Pexco and PPC Industries. The Apex deal is Spectrum’s first under the new ownership.

“We plan to continue pursuing acquisitions that fit our core objectives, to provide specialty plastic solutions on behalf of the medical device industry and our customers,” Shillingford said.
