Since 2019, Cadence, a manufacturer of critical components and assemblies for Minimally Invasive Surgery (MIS) applications, is represented by MedNet on the European market. Founded in the USA in 1985 as a sharps manufacturer, today Cadence employs over 575 people and is a full-service provider for metals and plastics fabrication along with an industry leading CNC sharpening capability. Join us "behind the scenes" of our new partner: In the second series we are showcasing Cadence's capabilities for laser fabrication.
Laser processing has become a fundamental manufacturing step for many new products. As a vertically integrated manufacturer Cadence provides various state-of-the-art laser technologies to optimize production output, to customize fabrication to customers’ needs and to meet unique industry challenges, like high precision and repeatability for critical medical components. As such, Cadence continues to develop and invest in laser processing technologies to meet the ever-changing needs of new product development.
Cadence offers consistently precise, reliable, high-quality welds for a wide range of materials for medical device components and subassemblies, as well as many other applications. With more than 3 million complex laser welded assemblies produced every year, Cadence is one of the leading welding partners in the industry. Using the latest technologies, Cadence can perform precise laser welding at great speed and efficiency, as well as repeatability. Via spot or seam welds Cadence can join not only similar but also dissimilar metals. Thus resulting in welds that provide excellent strength and visual appearance.
Benefits over conventional technologies
To provide the optimum weld you have to consider various circumstances and steps: the right focus of the laser, appropriate gas shielding, well-engineered joint design, ensuring repeatability, process variables such as correct type of laser for the material and thickness as well as reflectivity, conductivity and cleanliness of the material… — with its Advanced Welding LabTM Cadence integrates all these criteria into one unique, controlled process.
The laser drilling process is an inexpensive alternative to mechanical drilling, and very adaptable for small holes with large depth to diameter ratios. Precision laser drilling provides a repeatable, accurate hole that can be customized for all types of manufacturing industries and gives consistency especially to those, who require tight tolerances. The process can provide dynamic changes of hole diameter, depth and edge quality. Shaped holes of almost unlimited geometry are now possible producing unique benefits previously unobtainable by conventional processing techniques.
Cadence's laser ablation process is used in microfabrication to selectively remove material from a solid substrate through laser pulses. These short, laser beam pulses are controlled in a manner that removes material from a solid (or occasionally liquid) surface so quickly that the surrounding material absorbs very little heat, preventing thermal distortion in the base material.
Cadence capabilities include light or deep marking, customized to meet the need of each application, e. g. tubes for instrument shafts can be laser marked with company names, descriptions, or incremental measurements. Cadence also develops and tests for passive marking on certain applications.
Adapted to critical components and complex sub-assemblies, Cadence’s equipment is optimized as follows:
Cadence's LaserSwiss Machining capability combines 6-axis Swiss machining and laser cutting in one process and eliminates many manufacturing restrictions. You get the productivity of Swiss machining PLUS precise cuts from the laser cutter without having to move the part to another machine.
Multi-Axis Laser Cutting
Laser cutting is fast, flexible and cost-effective while providing a considerably better-finished result than other processes. In industries where precision is a high priority and quality is essential, it can be a tremendous production asset. It is a critical process needed for the manufacture of complex surgical device components.
Cadence’s laser cutting equipment is customized to the needs for surgical devices providing higher precision motion control and specific material handling such as automated coil feeding of flat stock and auto loading of tubing materials.
Materials: Steel, stainless steel, super alloys, copper, aluminium, brass, ceramic, quartz, plastic, wood and certain composites.
Our third series “Behind the Scence of Cadence” will deal with tube fabrication, including laser tube cutting capabilities.
