Micro Molding Innovation Since 1972
Miniature Tool & Die Founded
Miniature Tool & Die began its operations in the basement of founder Richard J. Tully’s 200-year-old Colonial home in Charlton, Massachusetts. The main product at that time was making connector molds for the Electronics Industry.
Acquired Layson Machine
In January of 1975, Miniature Tool & Die, Inc. bought an existing machine shop, Layson Machine, which was located at 100 Grove Street in Worcester, Massachusetts. Layson Machine had an EDM (Electrical Discharge Machine) that was the determining factor for the acquisition. This EDM machine was one of the very few in this area at the time. EDM was in its infancy but the potential was bright. This type of machining was not an easy sell and business was not too brisk in the mid ’70s.
New EDM, New Location
In June of 1977, Miniature Tool & Die, Inc. bought a new EDM machine and, at the same time, moved to 127 Cambridge Street in Worcester, Massachusetts. Business was picking up and EDM was now a force in the machining industry. We continued to build Connector molds for the Electronics Industry along with doing EDM work for mold shops in the area.
First Wire EDM Machine in New England
In 1982, Miniature Tool & Die bought a CNC Wire EDM Machine to expand the EDM capability further. This was one of the first machines of its kind in New England. That machine allowed MTD to create details that were otherwise not possible.
4 CNC Machines and Second Wire EDM Machine
In 1985, we purchased our second Wire EDM machine and have continued to expand in the CNC area with the purchase of the Elox CNC vertical EDM, the CNC Okuma Milling machine, an Okuma CNC Turning Center, and our newly acquired Herbert Walter 24 position Automated Tool Changer CNC EDM machine
New Home, New Niche
In 1998, Miniature Tool & Die, Inc. moved into our brand new employee designed 16,500 square foot facility on 15 Trolley Crossing in Charlton, Massachusetts. This was considered an investment in our future. This same year, we began working on a new niche: micro-mold building. Very little was known about micro mold building or micro molding in 1998, but we expected the future to be bright.
Micro and Bioabsorbable Molding Begins
Our previous mold making business allowed MTD to establish relationships with a few major medical OEMs. With the encouragement of those customers, we began micro molding in 2001. MTD’s first “micro” molding machine was a Nissei Denkey.
This is the year of the first bioabsorbable molding project at MTD as well.
Purchased First RJG eDart System Used for Micro Molding
1 Sodick vertical press and 1 Sodick horizontal press purchased. Purchased first RJG eDart system ever used for a micromolding application.
Micro Injection Molding Grows
Micro injection molding accounted for 25% of MTD’s revenue. MTD stopped producing micro tools for other companies.
NIH Grant for Studying Micro Flow
MTD was awarded the NIH grant for an SBIR program: studying micro flow of plastics. To study effective flow, had to add testing equipment – which became some of the building block tools of what we utilize today for micromolding projects. This was a 2-year process, ending in 2008. During 2006, high volume bioabsorbable micromolding also began at MTD.
Micro Molding Surpasses Machining
MTD’s micro molding revenue surpassed the machining revenue for the first time.
In 2008, the founder of MTD, Richard Tully, retired. With Dick’s retirement, the organization was passed onto the second generation led by Dick’s son, Dennis Tully. MTD remains committed to Dick’s original philosophy to find and commit to a niche as well as to respond quickly, precisely, and efficiently to our customer needs.
Upgraded In-House Tooling Department
Between 2008–2009, MTD upgraded all critical equipment in the in-house tooling department. We added Sarix micro EDM milling technology—the only system in North America at the time.
New Name for New Focus
On April 1, 2010, we began using our new name: MTD Micro Molding.
The expectation with the new name was to help people recognize that our new business is micro molding, while our foundation is very much MTD. And so began the mission of educating medical OEMs that smaller, better critical components are possible. The focus was on providing highly specialized products that meet the exact requirements of companies in the medical, electronics, and microfluidics fields.
In 2010, we also started working with international medical device companies. We stopped manufacturing turn-key molding cells for other companies, while keeping all tooling and micromolding operations under one roof at MTD’s facility.
Smallest Part in the World
Smallest part in the world created by MTD. The ophthalmic implant for glaucoma treatment weighs in at 0.00000313 grams, with a gate measuring .0018 x .0008 inches.
This year, drug-filled bioabsorbable material molding began. Pharma loss through extrusion was significantly higher than micro injection molding—practically no post-mold drug loss with MTD’s method.
MTD Micro Molding ranked #1274 in the Inc. 500|5000 list due to a 3-year growth percentage of 228%.
Cleanroom expansion: 1200 sq ft ISO Class 8 cleanroom to increase capacity for 8 more molding cells.
First MTD process technician to become a certified Master Molder.
Processor of the Year Finalist
Finalist for Plastics News’ Processor of the Year Award. First MTD molding technician obtained Plastics Technology & Engineering Certificate from the American Injection Molding Institute.
First Micro Injection Molder to Receive MedAccred Certification
MTD is the first micro injection molding company in the world to receive the MedAccred Certification. We also received ISO 13485 Certification. During this record sales year, we expanded the molding and tooling departments to best support our unique specialty in providing solutions for bioabsorbable and drug delivery components.
Manufacturing Excellence Award
MTD is the recipient of the 2017 Manufacturing Excellence Award based on its sharp focus on medical micromolding, intimate knowledge of its client’s needs, state of the art equipment, and continuous year-over-year revenue growth. This year, MTD also proudly celebrates their 45-year anniversary.
MTD Micro Molding made the Inc. 500|5000 list for the second time due to a 3-year growth percentage of 48%.
FDA Registration & Best Places to Work
MTD obtained FDA registration at the start of 2018. This registration allows for additional services to take place at our facility for our customers including custom assembly, packaging, and labeling operations.
MTD was included in the Best Places to Work list for 2018.
MTD Micro Molding was also honored as a Processor of the Year finalist for 2017 and the recipient of the Employee Excellence Award by Plastics News.
The company also made significant investments in innovation this year, with purchases like a Gas Chromatography System and North America’s first Mitsubishi MX600 oil wire EDM machine.
Processor of the Year
MTD was named the Plastics News Processor of the Year, the plastics industry’s most prestigious award, becoming the smallest company to win the title in its 22 years.
The company was also named one of the Best Places to Work in the plastics industry for the second year in a row.
The awards were bittersweet due to the loss of MTD’s president, Dennis Tully, on February 28—just one week before the awards ceremony.
in 2022, MTD celebrates 50 years of miniaturization.
In March, it was announced that MTD Micro Molding made the list of Best Places to Work for the fifth consecutive year.
