Nitinol Processing

Laser cutting

Using advanced laser technology, GTI ensures precision manufacturing of Nitinol components. Nitinol laser cutting allows for the intricate and delicate designs needed in medical devices. The precision and accuracy of laser manufacturing are essential for producing components that meet the rigorous standards of the medical industry.

Laser welding
Laser welding is another critical process GTI offers for Nitinol devices. Laser welding of Nitinol requires specific expertise due to the alloy’s unique characteristics. Our laser welding capabilities allow for smooth joining of Nitinol parts, ensuring structural integrity without compromising the material’s properties, such as flexibility and shape memory. This process is essential in creating durable, reliable medical devices.

Electropolishing and surface treatments  
Surface finish is a vital aspect of any medical device. GTI provides electropolishing and other surface treatments that enhance the biocompatibility and corrosion resistance of materials such as Nitinol, stainless steel, titanium, and others.

Shape setting and heat treatment   
Shape setting is a key step in Nitinol processing. Nitinol’s shape-memory property allows it to return to its predetermined shape when exposed to a specific temperature.

Austenite finish temperature (Af) testing and reporting
One of the key properties of Nitinol is its ability to undergo a phase transformation between martensite and austenite phases. The Austenite finish temperature (Af) is crucial for determining the working range of Nitinol devices.

In-house design and manufacturing of mandrels and fixtures
GTI has the in-house capability to manufacture mandrels and fixtures used in the processing of Nitinol devices. This ensures tight control over the entire manufacturing process, from initial design to final production, and allows us to customize fixtures to meet the specific needs of each project.
