John Hassall supplies custom-formed and machined parts utilized in a variety of medical applications. These parts typically perform life-critical functions that require extreme precision and very narrow tolerances. Where durability is a concern, John Hassall can produce medical electronic and electro-mechanical components using high strength alloys that are either difficult to form or are very difficult to machine. John Hassall supports the medical industry with its ISO 9001:2008 certified U.S-based custom manufacturing capabilities, complemented by an in-house heat-treating facility and metallurgical laboratory certified to NADCAP and AS 9102 standards for defense-related medical equipment.
Stethoscopes, hypodermic needles, prosthetic devices, automatic external defibrillators (AEDs), surgical devices, general medical electronics, and more.
Close tolerance electro-mechanical parts, hubs, ferrules, bushings, connectors, contacts, electrodes, rivets, pins, screws, and more.
Various grades of stainless steel, cobalt based alloys, titanium, aluminum, brass, and more.

John Hassall offers a long tradition of unsurpassed quality and price competitiveness at its 65,000 square foot US based manufacturing facility. For parts not ideally suited for domestic manufacturing, we offer the option of importing special cold-formed metal parts, as well as precision-machined components from two time-tested high quality sources in Japan and China. All such product is distributed under the purview of Hassall’s general quality systems and procedures.
