Contract manufacturer Micro (Somerset, N.J.) this week announced its 75th anniversary in business.

Founded in 1945 as Micro Stamping Corp. in Maplewood, N.J., the family-owned company specializes in precision medical components, sub-assemblies and complete devices for laparoscopic surgical procedures. Operations have expanded from 28,000-square feet to nearly 180,000-square feet, and the company recently dedicated an expanded research and development center.

Micro was founded by four partners including Frank Semcer Sr., who worked at the company until 1986, retiring at age 83. Four of his brothers joined the company. His son, Frank J. Semcer Sr., joined in 1969 and purchased the company eight years later. Today, four of his children work at Micro, which now employs more than 450 people and has annual sales revenue exceeding $100 million.

“We are incredibly proud to celebrate 75 years providing engineering and technical expertise, fulfilling our vision to help our customers save lives,” said Micro president Brian Semcer in a news release. “As a trusted and valued product development partner to our clients, innovation has always been the hallmark of our business and we continually seek ways to improve and reinvest in technology, equipment, state-of-the-art facilities and training to create new and better solutions for customers and their patients.”
