CHARLTON, MA – (April 13, 2017) – MTD Micro Molding (, a long-time leader and expert problem solver in micro-injection molding for the medical device industry, is proud to announce its forty-fifth year in the micro manufacturing business.

150 years ago, Worcester, Mass. was a hub for manufacturing and industrial innovation. In the mid-1900s, the city’s industrial base faded away ­except for a few key companies, who learned to adapt and thrive. As the Worcester Historical Museum says, “New inventions, innovations, and businesses keep Worcester’s manufacturing legacy alive, providing employment for thousands.” Richard Tully was one of those innovators, founding Miniature Tool & Die (now MTD Micro Molding) in 1972 in the basement of his home as a manufacturer of miniature connector injection molds for the electronics industry — and later miniature molds for medical OEMs. By 2001, MTD began producing highly complex micro injection molded medical device components, including bioabsorbable molded parts.

Since then, Tully’s son Dennis assumed ownership of the company. As technology rapidly developed and customer needs became more exacting, the company narrowed its business to focus exclusively on medical micro molding. Being one of only a few companies to focus 100% on this niche enabled MTD to become globally recognized as a leader in manufacturing the most cutting-edge breakthroughs for the micro medical market.

Today, MTD resides in a state-of-the-art facility in Charlton, complete with cleanroom manufacturing space, in-house tooling, ISO 13485 certification, and leading edge molding and tooling technology. Thanks to stable year-over-year revenue growth, MTD plans to expand its facility in the near future to provide even more specialty solutions for the unique needs of bioabsorbable and drug delivery applications.

“MTD has a 45-year tradition of helping customers refine their designs and select the best material for optimal part functionality while maximizing costs” said Dennis Tully, president of MTD Micro Molding. He added, “I am proud of MTD’s past accomplishments and excited about what the future holds. After all, we spent our first 45 years preparing for the challenges the next 45 years will bring”.
