A global leader in custom medical extrusion since 1989, operating as an extension of your own development team.
About Microspec
Microspec is a medical extrusion company in Peterborough, New Hampshire. With proprietary processes and tools, we have earned a global reputation for extruding some of the smallest, most complex and tightly toleranced medical parts in the industry. We extrude in any quantity, from experimental to commercial runs and from small development lots to millions of parts per year.
Founded in 1989 by Tim Steele, we have grown from one extruder in a 1,200 square foot building to 22 extruders, about 120 people and a 46,500 square foot facility in Peterborough, New Hampshire. In 2025 we received an Outstanding Supplier Award, and in 2024 we celebrated our 35th anniversary.

Customer focus
We operate as a trusted extension of your product development team, with the same commitment to success.
Our customer service team guides you through every step of a request for quote. We discuss your objectives and specifications, including OD and ID tolerances, wall thickness, number of lumens and their dimensions, cut length, material and durometer, and the schedule and quantities for prototype, validation and commercial runs.
If you need a tube that performs a new function, an unusually shaped lumen or an especially complex delivery system, talk to us. We may already be experimenting with materials, processes and tools that can turn your idea into an extrudable product.
We alert you when new sources and new extrusion materials come onto the market. We call when our records show your inventory is running low. We keep relationships with vendors whose materials and service we trust, and we take pride in our dock-to-stock certifications.
