Solution
Stainless steel needle tube sidewall punching
Typical Materials：
- Metal Cannula: 316L Stainless Steel (ASTM F138 Standard), Nickel-Titanium Alloy (Memory Alloy)
- Polymer Cannula: Polycarbonate (PC), Polyetheretherketone (PEEK)
- Wall Thickness Range: 0.1-1.0 mm (Common metal cannula 0.2-0.5 mm, plastic cannula 0.3-1.2 mm)
Core Requirements：
- Aperture Accuracy: 20-500 μm (such as microneedle arrays, drug release holes)
- Quality Requirements: Burr-free (Ra < 1.6 μm), Zero Thermal Material Denaturation, Biocompatibility
