Bibber, who is CEO after the ownership change, said the company is "experiencing unprecedented growth," particularly from business with its medical and drug delivery customers.
The firm makes ultrasmall plastic parts down to .00004 grams and components for applications like robot surgical equipment, sensors, transdermal patches and neurovascular implants.
It also builds its own molds and does microautomated assembly, micro 3D printing and computerized tomography scanning.
"We're doing micromolding and microautomated assemblies," she said in an interview. "We have 40 mold makers on staff, which is the largest of the micromolders. … That way we can take on many large mold projects with multiple parts, and therefore the assembly of multiple parts."
Bibber said the company has gone from five microinjection molding machines in 2017 to 15 today.
"Having the micromolding and the automated assembly in house helps us to certainly grow," she said.
Hudalla founded Isometric as a traditional mold making company in 1990, but in 2013 Bibber and Shakal came on board to transition it into micromolding.
"The whole idea was to start the micromolding business and allow ourselves to buy the business over time," she said. "It took us seven years. We came on board with the succession plan in mind."
She said Hudalla had "the insight and a very innovative, creative mind to bring this in. He saw a higher value there for the mold company."
Previously, Bibber was a founding partner of MTD Micro Molding in Charlton, Mass.
Shakal, who is president after the ownership change, called the purchase "the progressive realization of a lifelong goal that was made possible when Donna and I partnered with Mike Hudalla."
Previously, Bibber had been the vice president of business development and Shakal had been vice president of operations.
