CWT provides customized medical wire coiling solutions that meet or exceed design requirements needed by the top OEMs in the medical device industry.
CWT’s technical expertise, unique processes, and wide range of material offerings, such as nitinol, provide an ability to produce complex medical coils with tight tolerances for the most challenging design specification.
Micro-Grinding
CWT offers medical grinding capabilities to manufacture guidewires, core wires, mandrels, hypotubes, K-Wires, orthopedic pins, needle prototypes, and nitinol components.
Centerless grinding allows for optimal levels of stiffness and flexibility while accommodating tapers of any angle. While profile grinding is utilized for threads, points, and other shapes.
Wireforms
CWT specializes in custom wireforms and components made from precision round or flat wire for medical, dental, and surgical device manufacturers. Laser and plasma welding services can be utilized to provide complete assemblies.
Nitinol Components
Nitinol coils and wireforms offer unique properties which can be superior to stainless steel in certain cases. Its unique elastic, shape memory properties allow for the material to return to various shapes when reacting with external environment changes.
Cleanroom Assembly
CWT’s 2,000 sq ft ISO Class 7 cleanroom provides unique and comprehensive manufacturing, assembly, and packaging capabilities. Products include custom guidewires, stylets, and specialized components for the medical, dental and surgical industries.
Laser Marking
Laser marking can add unique identifiers such as part numbers, lot numbers, descriptions, and company logos to a variety of parts. CWT can add depth bands to guide wires, k-wires, and pins to present visual feedback to an end user on how far a component may be inserted.
