Micro-Nozzle Molding with an Inner Diameter of ø0.03 mm—Pushing Beyond the Limits of Machining and Laser Processing

‍

Exceeding the “ø0.05 mm” threshold—long considered the limit of micro-machining—Micro MIM Europe GmbH mass-produces “inner diameters of ø0.03 mm,” thinner than a strand of hair, in a fully net-shape form (requiring no post-processing).

‍

This approach fundamentally eliminates issues associated with other manufacturing methods—such as the adhesion of molten residue and the heat-affected zone (HAZ) caused by laser processing, as well as microscopic burrs resulting from machining. Using ultra-fine powder technology, we achieve a smooth surface with an internal roughness of Ra ≤ 0.3 μm directly after sintering. Even in extremely small flow channels that cannot be reached by polishing, this prevents pressure loss, clogging, and the risk of blood or pharmaceutical solution stagnation.

‍

- Breaking the Limits of Machining (ø0.03 mm): Stable mass production even at extremely small diameters, without the risk of drill breakage or center deviation.

‍

- Zero thermal stress or dross: No heat distortion or spatter typical of laser processing, maintaining roundness and flow path precision.

‍

- No internal polishing required (Ra ≤ 0.3 μm): Forms flow paths with a near-mirror finish, preventing protein adsorption and turbulence.

‍

- Integral flow path molding: Seamlessly molds complex tapers and multi-orifice nozzles, eliminating fluid leakage and dead volume.
