Laser Cutting for Stainless Steel Capillary Tubes and Medical Components
Laser Cutting in Medical Application Manufacturing
Laser cutting has revolutionized medical device manufacturing, enabling micro-precision cutting of complex geometries in stainless steel, titanium, cobalt-chromium, and nitinol. From cardiovascular stents to surgical shaver blades, laser cutting delivers the precision, quality, and consistency required for life-saving medical applications.
Medical Application Applications
Cardiovascular Stents
Stents are manufactured by laser cutting tubular patterns into nitinol or CoCr tubes, then crimping and expanding for delivery.
| Parameter | Specification |
|---|---|
| Material | Nitinol, CoCr, 316L |
| OD Range | 1.5mm – 8.0mm |
| Wall Thickness | 0.1mm – 0.25mm |
| Cut width (kerf) | 0.05-0.1mm |
| Pattern complexity | High (hundreds of features) |
Surgical Shaver Blades
Shaver blades are manufactured by laser cutting cutting windows and helical grooves into 420J2 or CoCr tubes.
| Parameter | Specification |
|---|---|
| Material | 420J2, CoCrMo |
| OD Range | 2.0mm – 5.0mm |
| Wall Thickness | 0.15mm – 0.3mm |
| Cutting window | 180°, 270°, 360° |
Surgical Needles
Needles are cut to length with laser cutting for burr-free, precision ends.
| Parameter | Specification |
|---|---|
| Material | 304, 316L, 420J2 |
| Gauge Range | 18G – 32G |
| Length tolerance | ±0.05mm |
