December 2020 – Menlo Park, CA – Stack Plastics, a custom injection molder out of Menlo Park, CA has been acquired by Springboard Manufacturing Solutions, a portfolio company of HC Private Investments. Stack provides fully-integrated plastic manufacturing and micromolding services to its global medical device customers. Stack’s operations will continue to be led by its executive team, including John Huynh and Scott Smith.

“Stack is a leading medical injection molder that has played an integral role in its customers’ manufacturing process and product development for 25 years. We are delighted to partner with Stack’s talented management team to offer increased capabilities and a national manufacturing footprint to our combined customer base,” said Doug Constable, Springboard CEO. “Our goal is to focus our growth in the medical device area. [Stack] has a lot of good OEM relationships in some solid medical device companies.”

The addition of Stack adds a “niche” business that Springboard “had less presence in,” with smaller manufacturing sizes ranging from micromolding to 150-ton machines.

Originally established in 1975 as a custom injection molder dedicated to quality and customer service, Springboard provides customers with quality products in conjunction with value-added services relating to engineering, product design, material selection, process mapping, assembly, and packaging.

HC Private Investments (“HCPI”) is a private equity investment firm focused on making investments between $5 million to $30 million in lower middle-market manufacturing businesses within the consumer and industrial markets.

This acquisition brings Springboard up to three manufacturing facilities in California and Indiana with more than 130 injection molding presses ranging from 25 tons to 1,300 tons and more than 300 employees.

MBS advised Stack in the transaction.
