What MTD Micro Molding does
MTD Micro Molding is a privately held U.S. contract manufacturer specializing exclusively in micro injection molded components for medical device OEMs. Founded in 1972 as Miniature Tool & Die in Worcester, Massachusetts and now headquartered in Charlton, MA, the company has operated continuously for over 50 years and rebranded to MTD Micro Molding in 2010 to reflect its specialized focus. The firm serves Fortune 500 medical device manufacturers including Abbott, Boston Scientific, Cardinal Health, Medtronic, and St. Jude Medical, with end applications spanning minimally invasive devices, bioabsorbable implants, overmolded electrodes, drug delivery components, vascular devices, and microendoscopes.
The company operates a vertically integrated single-source model spanning micro materials, micro part design (DFM), micro tooling, micro molding, micro metrology, and micro assembly and packaging, all housed under one roof in ISO Class 8 cleanrooms. Core technical capabilities include one of only two Sarix Micro EDM Milling systems in the country (enabling 5-micron corner radii and 0.000004 inch tolerance resolution), ultrasonic molding technology, RJG eDart process monitoring, CT scanning, and an optical 3D metrology system with nanometer precision added in September 2025. MTD holds the distinction of being the first micromolding company in the world to achieve MedAccred Certification (2016), alongside ISO 13485:2016, ISO 15378:2017, ISO 9001:2015, and FDA registration.
MTD generates revenue through project-based contract manufacturing engagements with quote-based, multi-year pricing tied to tool design, material specification, tolerance complexity, and production volume. Go-to-market is sales-led and enterprise-focused, combining direct field sales with regional sales representatives (including West-Tech Materials for California). The firm markets primarily through industry thought leadership in publications such as Medical Product Outsourcing and Plastics News, supplemented by trade show presence at MD&M West and MD&M East. Leadership transitioned in June 2026 with John Clark appointed CEO, succeeding Gary Hulecki, who had led the company following the 2019 passing of former President Dennis Tully.
