Medical Wire Components & Assemblies for the Medical Device Industry
Now entering its 20th year in business, US-based CWT is a leading medical device original equipment manufacturer (OEM), with experience in the design and development of medical wire components. Offering products and services in the areas of coiling, grinding and wire forming, the company is well equipped to customise wire products for a variety of applications, such as guidewire coils and assemblies, Kirschner wires, mandrels and profile ground custom tips.
Medical Wire Coiling
CWT provides customised medical wire coiling solutions that meet or exceed design requirements needed by the top OEMs in the medical device industry today. A wide range of material offerings, technical expertise, and unique processes provide an ability to produce complex medical coils with tight tolerances for the most challenging of design specifications. Also available is the new QwikCoil program, offering lightning-fast turnaround on R&D services and coiling orders.
Precision Grinding Services
CWT specialises in OD profile and centerless grinding for products like guidewires, K-wires, orthopedic pins, needle prototypes, ground hypotubes, mandrels, and additional medical related products. Many projects utilise stainless steel 304 and nitinol wire to produce cores wires. Capabilities can accommodate 10 foot lengths, with diameters between .006″ and .035″ in size..
Wire Forms for Medical Devices
CWT produces custom wire forms using materials such as fine wires, round wires and flat wires. Highly automated CNC forming equipment is optimized for wire .032″ and smaller with capabilities to form larger diameter wires as well. Nitinol can be shape set by placing an exact fixture and run through a time/temperature controlled heat set process with a quench to set the final shape. Transformation temperatures can be altered and set to the customer’s specific needs.
Cleanroom Assemblies
Assembly services are performed in-house in an ISO 13485 Class 7 (2,000 sq. ft.) cleanroom, and serve a variety of medical device OEM’s, designers, and researchers who are looking for cleanroom assembly services performed in the United States. The facility is coupled with coiling, grinding, and wire forming services enabling CWT to provide shorter lead times for fully assembled medical device components.
Nitinol Products
Expertise with coiling stainless steel wire laid the foundation for success with nitinol. To serve the ever-changing needs of the industry, CWT has invested in dedicated equipment to its nitinol manufacturing line. Increasing demand from top OEMs to diversify their product portfolios has driven CWT to overcome manufacturing challenges associated with nickel titanium. With over 10 years of Nitinol processing experience, the engineering team’s ability to quickly produce samples and prototypes helps innovative startups fast-track new product development.
Value Add Services
CWT offers a full suite of assembly capabilities utilising laser welding, plasma welding, medical grade adhesives, and crimping techniques to mechanically bond components. Additional value-added services include laser marking, pad printing, wire EDM cutting, passivation and electropolishing. Using strategic suppliers, CWT can add PTFE coatings to most of the products it manufactures and can also selectively grind the coating away to meet design requirements. Having many of these services in-house allows CWT to offer competitive pricing and shorter lead times for its medical devices.

Nitinol: The Superelastic Metal that Remembers its Shape
The origin of nitinol dates back to 1959, when US Navy scientists began experimenting with new materials to be used in naval missiles. By combining nickel and titanium, they discovered a unique alloy which remained strong and durable, no matter how often it was bent and reshaped. Over time these properties proved to be highly valuable when applied to small medical devices for insertion into hard-to-reach places by surgeons. Soon after it started to be tested and experimented within the medical setting, a third key benefit was found, with its metallic composition offering high levels of both biocompatibility and corrosion resistance when treated, making it an ideal material for use in the human body. Since the 1990s, nitinol has proven to be a critical material within a wide range of medical devices with an ever-growing list of applications.
