-
Medical & Clinical Use: Hypodermic needles, biopsy needles, acupuncture needles, catheter introducers, and specialized surgical needles.
-
Laboratory & Research: Micro-injection systems, sample collection probes, and precision fluid transfer tools.
-
Industrial & Technical Applications: Precision dispensing nozzles for adhesives or lubricants, delicate probing instruments, and fine mechanical assembly tools.
Product Description:
We specialize in the end-to-end custom fabrication of 304 stainless steel capillary tubes into cannula needles (hollow-core) and three-bevel needles (solid or hollow, featuring a triple-faceted ground point). Our comprehensive process includes precision tube cutting, point grinding/forming to create sharp, consistent bevels, followed by uniform sandblasting for an optimal matte, non-reflective surface finish. Finally, we apply high-precision, permanent graduation marking via laser engraving for accurate depth indication. Utilizing high-grade 304 stainless steel ensures excellent corrosion resistance, mechanical strength, and cost-effectiveness for applications where the superior biocompatibility of 316L is not mandatory.
Product Technical Parameters:
| Category | Parameter | Details / Specification |
|---|---|---|
| Base Material | Material Standard | AISI 304 Stainless Steel / UNS S30400 |
| Key Properties | Good corrosion resistance, high strength, excellent formability and sharpness retention. | |
| Needle Types | Cannula Needle | Hollow core for fluid passage. Customizable inner/outer diameter and tip geometry (e.g., lancet, pencil point). |
| Three-Bevel Needle | Triple-faceted ground point for superior sharpness and controlled penetration. Can be solid or hollow. | |
| Processing | Point Grinding/Forming | Precision grinding to create sharp, consistent bevels (e.g., 12°-20° bevel angles) with minimal burrs. |
| Sandblasting | Uniform matte finish for reduced glare, improved grip, and enhanced aesthetic. Controlled surface roughness. | |
| Graduation Marking | Permanent, high-contrast laser engraving of depth scales. Typical resolutions: 1mm, 5mm, or 10mm increments. Custom logos/text available. | |
| General Specifications | Outer Diameter (OD) | 0.2 mm to 2.0 mm (standard range, customizable). |
| Inner Diameter (ID) | For cannulas: Custom based on OD and wall thickness. Can be ultra-fine. | |
| Wall Thickness | 0.05 mm to 0.3 mm (typical for cannulas). | |
| Needle Length | Custom cut, typically from 10 mm to 150 mm. | |
| Bevel Angle | Standard: 12°, 15°, 18°. Custom angles available. | |
| Dimensional Tolerance | OD: ±0.01mm; Length: ±0.1mm (tighter tolerances achievable). | |
| Quality | Sharpness Testing | Can meet industry-standard sharpness penetration force requirements. |
| Surface Finish | Smooth, debris-free surface post-blasting. Bioburden control available for medical applications. | |
| Cleanliness & Packaging | Clean-room packaging optional. Standard packaging ensures protection from damage and contamination. |
