Once skittish about outsourcing, most medical device OEMs today consider outsourcing vital to success. They know that contracting out metal fabrication to a precision supplier can help them improve product design while reducing production costs. Metal fabricators stay up to date on metal trends and technologies, such as laser cutting, machining, milling, stamping, surface treating, and testing. Below are some tips on how to select a metal fabrication provider:

Check credentials. Not all metal fabrication shops are created equal. The OEM should ensure that the prospective partner is certified to the standards required for the application. For most OEMs, this means ISO 9001 and/or ISO 13485 certification.
Tour the shop. Is the facility clean and orderly? Is the manufacturing equipment up to snuff and is the work flow smooth and efficient? The supplier should use a paperless enterprise resource planning (ERP) system to manage production, scheduling, pricing, and quality. It should also use the latest 3-D modeling software to verify the form, fit, and function of devices.
Meet the engineers. An experienced and collaborative engineering team is vital to good product development. The outsourcer’s team should be eager to share ideas, find mistakes, and suggest design for manufacturing (DFM) changes to improve product design. The team should assist through all phases of production, including concept, prototyping, qualification, validation, and full-scale production.
Check quality and capabilities. The OEM should ask the vendor about past and current clients and projects. Has the vendor manufactured for a medical device OEM before? Does it perform most or all of the work in-house, or does it outsource? The supplier should accommodate both the OEM’s rapid prototype and finished production schedules.
Take a tool inventory. Once the OEM has selected a fabrication partner, it should research the company’s tool inventory. Using the vendor’s tools can expedite the project.
