Medical Micro Pipe
Product Description
Mass production of micro-hollow and 3D flow-path pipes, pushing the boundaries of machining and bending
Micro MIM Europe GmbH is capable of mass-producing micro-pipes with complex internal flow paths—such as ‘multi-branch, irregular cross-sections and 3D spirals’—which are impossible to achieve through conventional machining, in a fully net-shape form.
Through fully integrated moulding—which eliminates the need for micro-welding or brazing—we eradicate fluid leaks and pooling caused by joint defects. Quality assurance for the uniform wall thickness, internal defects and tight tolerances of these ultra-fine flow channels—which cannot be machined—is guaranteed from all angles by our high-end non-destructive 3D measurement and evaluation system.
Four key strengths that balance design flexibility and reliability
- Integral moulding of freely curved 3D holes and irregular cross-sections
Overcoming the limitations of deep-hole drills, which can only machine straight holes. We seamlessly mould ideal flow paths that minimise fluid resistance, as well as multi-branch nozzles.
- Highly smooth internal surfaces achieved without polishing
Even microscopic bends, which polishing media cannot reach, are formed with a smooth sintered surface. This significantly reduces the risks of turbulence, protein adsorption and thrombus formation.
- Verification of internal quality and flow paths using high-resolution X-ray CT (Nikon Metrology MCT225)
Non-destructive visualisation of internal defects, porosity and internal wall thickness in all ultra-small pipes that cannot be cut for inspection. Through direct 3D comparison with CAD data, the geometric accuracy of micro-flow paths is verified rapidly and precisely.
- A measurement system covering everything from nano-scale surfaces to geometric tolerances
We combine non-contact evaluation of the fine texture (Ra/Sa) of flow paths and edges using ‘Bruker Alicona’ with multi-sensor 3D measurement using ‘ZEISS O-Inspect / ATOS Q’. This ensures compliance with the stringent geometric tolerances required for medical-grade products at high throughput.
