【Conventional Technologies and Their Limitations】
Traditional machining methods cannot consistently achieve sub-micron accuracy. Conventional processes are often limited to micron-level tolerances and struggle with hard-to-cut materials like tungsten carbide and ceramics. This restricts their use in advanced fields such as medical devices and semiconductors, where extreme precision and durability are essential.

【Sanwa Creation’s Competitive Advantage】
Sanwa Creation overcomes these limitations with ultra-precision micron pins manufactured through centerless grinding and proprietary Nanogrind technology. Using tungsten carbide, the company achieves:
・Outer diameter tolerance: ±0.1 μm
・Roundness: 0.06 μm
・Surface roughness: Ra 0.0239 μm
・Diameters starting from 0.01 mm, lengths up to 2,000 mm

These values exceed conventional machining capabilities, enabling stable and reliable performance even under demanding conditions.

【Nanogrind Technology】
Nanogrind employs diamond grinding wheels and powder to reach nanometer-level accuracy. Unlike other companies, Sanwa Creation can produce:
・Micron pins with stepped or tapered designs
・Ultra-long shafts with consistent precision
・Sub-micron finishes that reduce wear and extend product life

【Applications in Medical Devices】
Ultra-precision tungsten carbide micron pins are used in:
・DNA micro-injection systems
・Catheter components from nickel-titanium alloys
・Artificial dialysis plungers
・Manipulator devices with sub-micron tips

【Applications in the Semiconductor Industry】
In the semiconductor sector, applications include:
・LED manufacturing nozzles
・Inkjet printer heads
・Fuel injection pins for automotive devices
・Precision shafts for processing equipment

【Quality Assurance】
Sanwa Creation ensures strict quality control through:
・ISO9001 certification
・RoHS compliance
・Inspection reports with every order
・Calibration certificates and full traceability upon request
・Advanced metrology including 3D systems, roundness testers, and laser microscopes

【Conclusion】
By combining tungsten carbide materials, Nanogrind technology, and strict quality management, Sanwa Creation provides micron pins that surpass conventional machining. Customers benefit from higher reliability, extended component life, and superior competitiveness in medical and semiconductor markets.
