Micro pins are ultra-fine components required in cutting-edge fields such as medical and semiconductor industries. These pins, measuring just tens of microns in diameter, determine the operation and measurement accuracy of precision instruments.
This section introduces the applications and manufacturing technologies of ultra-precision micro pins.

【Applications】
・Medical: Manipulator operation pins for genetic research
・Semiconductor: Pusher pins for substrates and chips

【Manufacturing Technology】
・Centerless grinding achieving outer diameter tolerance of ±0.1μm
・Nano-grinding achieving 10-nanometer precision
・Small-diameter machining starting from a minimum diameter of φ0.01mm
・Capability for long lengths and irregular shapes
・Quality management based on ISO9001 and issuance of calibration certificates

【Case Studies】
Manipulator pins for genetic research devices feature tips finished to under 1μm. Fuel injection nozzle pins can be mass-produced using ultra-hard alloy fine wire with a diameter of 0.05mm.

【Summary】
Micro-pins are essential components meeting the advanced demands of cutting-edge industries. Sanwa Creation's technology achieves high precision despite extremely small diameters, supporting applications from research to mass production.
