Precision Swaging for Medical Devices

Swaging is a cold forming process that involves reducing the diameter of a tube by forcing it through a die. As a result, swaging plays a crucial role in creating custom formed medical device tubing with complex shapes and features. What sets modern swaging apart is its ability to achieve very complex shaped features to meet specific needs for patient care.

State of the art manufacturing technologies produce swaged components with diameters as small as tens of microns. As a result, these technologies enable the creation of ultrafine medical instruments and implants. Advanced control systems and computer-aided software furthermore ensure consistency and precision in the swaging process. Hence, these systems meet the most stringent requirements of medical applications.

Micro swaging finds innovative applications in the production of intricate and minimally invasive surgical instruments. Some recent examples of these life saving products include devices such as endoscopic robots, micro drug delivery systems and more. Additionally, micro-swaged components are integral to the development of implantable devices like neurostimulators and intercranial stents, where compactness and precision are paramount.

Tube Bending and Forming

Tube bending and forming are versatile manufacturing processes used to shape tubing into complex configurations without compromising its structural integrity. For medical devices, bending and forming play a pivotal role in creating devices such as trocars, cannula, and other products requiring intricate tube geometries.

With advancements in manufacturing technologies, tube bending and forming processes can now achieve tighter bend radii and more complex shapes than ever before. High-precision forming equipment ensures accuracy down to the micrometer-scale.

These bending and forming technologies enable the creation of intricately shaped trocars and cannula. These devices are furthermore tailored to meet the precise requirements of complex surgical procedures and varying anatomies. Some cutting edge example applications include laparoscopic surgeries, robotic-assisted surgeries, and neurosurgical interventions. These custom-shaped instruments allow surgeons to navigate through tight spaces and delicate anatomical structures with enhanced precision and efficiency. Hence, these tools are facilitating minimally invasive approaches and promoting faster patient recovery.

Tube Swaging and Forming for Medical Device Assemblies

Bent and swaged micro tubing often require intricate assembly into complex medical devices. Hence, it is advantageous to combine these processes with cutting edge assembly technologies like laser welding and insert molding. Laser welding allows for the seamless joining of swaged or formed tubes with other components, ensuring structural integrity and hermetic seals critical for implantable devices or fluid delivery systems. Similarly, insert molding enables the integration of swaged or bent tubes into plastic assemblies. This enhances functionality by integrating the beneficial features associated with micro molding such as luer lock interfaces. Furthermore, this can reduce assembly complexity by eliminating problematic manual adhesive bonds. Together, these technologies enable the development of innovative medical devices that meet stringent performance requirements while optimizing manufacturing efficiency.
