Medical technology
In medical technology series production, manufacturing costs are often driven less by component design than by production requirements: required dimensions must be maintained consistently, surfaces require additional post-processing, and every additional process step increases effort, risk, and cost.
Our forming technologies address exactly these factors: they are chipless, achieve very tight tolerances, deliver high surface quality, and enable targeted work hardening in the formed area. The result: precise component production and stable process chains.
Challenges in medical technology
– Felss solutions
In series production of medical technology components, the highest requirements meet economic constraints. Dimensional accuracy, surface quality, and process reliability must be ensured consistently, while efficiency demands continue to increase.
Felss offers technologies for
series-ready medical technology components:
Our forming processes are designed for targeted series production: short cycle times, high repeatability, and precise manufacturing.
Tight tolerances in the process
Components are produced directly in the forming process with very tight tolerances. Stable, reproducible, and suitable for series production.
High surface quality
High surface quality reduces or eliminates post-processing and provides the foundation for functional components.
Non-cutting forming
Material is formed rather than removed, reducing material loss and improving cost efficiency.
Targeted work hardening
Mechanical properties are influenced locally during the forming process and precisely tailored along the component.
Felss solutions for medical technology
In medical technology, geometry, material properties, and tolerances determine functionality, durability, and process reliability. Our forming processes are used wherever thin-walled and solid, rotationally symmetrical components must be manufactured with precision and reproducibility.
Thin-walled and geometrically demanding components
As wall thicknesses decrease, demands on process control and precision increase. Our forming technologies enable stable geometries and defined transition areas even under these conditions.
Endoscopes
Rotary swaging forms the endoscope tip radius and prepares it for the subsequent grinding process.
Anaesthesia cannulas and injection needles
Needle tip forming prior to grinding, with closure possible without additional material.
Catheters and cannulas
Even wall thicknesses and high surface quality directly from the forming process.
Functional areas and targeted work hardening
For certain components, the focus is not on the entire geometry but on a clearly defined area. Through targeted forming, material properties can be locally influenced, and functional zones can be reproducibly defined.
Electrode for cardiac catheters
Attaching the sleeve to the catheter tube.
Aneurysm clips
Rotary swaging of the necked section enables local hardening and improves bending performance.
Advantages
Tight tolerances, cost-efficient processes, and targeted work hardening even in very small components.
Structural and load-bearing components
For structurally loaded components, wall thickness transitions, stiffness, and material utilisation are key. Forming processes enable functional geometries and cost-efficient manufacturing without unnecessary machining.
Intramedullary nails and implants
Axial forming and roller burnishing of longitudinal profiles enable targeted wall thickness transitions, increased strength and rigidity, and low component weight.
Medical instruments
Rotary swaging provides local work hardening in functional areas and high surface quality.
Support rods for dental chairs
Forming in the functional area for good surface finish and hardening in the formed area.
Your advantage with Felss
Our forming technologies combine precision, process reliability, and cost efficiency in series production. We develop solutions precisely tailored to the requirements of medical technology — from component geometry to stable process chains.
Technologies that drive progress
Our forming technologies — axial forming, rotary swaging, and rolling — form the basis for precise, reproducible manufacturing solutions in medical technology.
Axial forming
Targeted forming along the component axis modifies the cross-section and creates precise internal and external profiles.
- very high repeatability
- short cycle times
- increased strength through work hardening
Rotary swaging
Forming components with radially acting tools directly to the final contour.
- very tight tolerances (process-dependent < ±0.01 mm to ±0.05 mm)
- surface finishes up to Ra 0.1 µm, depending on the process
- non-cutting process with no material loss; work hardening increases tensile and yield strength
Rolling
Forming with rotating tools to reduce or profile a cross-section.
- very precise geometries
- cost-efficient profiling without machining
- stable component properties through forming
Combination of processes
Depending on the requirements, multiple technologies can be combined to optimally balance precision, strength, and efficiency.
