304 316L Stainless Steel Capillary Medical Accessories Processing
Product Description
These are high-precision, custom-manufactured capillary needles made from 304 or 316L stainless steel. The core manufacturing process involves precision tapering of one end to form a sharp, consistent tip. The needles undergo sandblasting to achieve a uniform, matte, and non-reflective surface finish, which also provides improved grip. Custom laser marking and precise scale graduations are applied for clear identification and measurement. This is a comprehensive custom machining service tailored to specific application requirements, leveraging the excellent corrosion resistance and durability of stainless steel.
Product Applications
Medical & Life Sciences: Hypodermic needles, biopsy needles, micro-sampling probes, fluid transfer in lab devices, ophthalmic surgery instruments.
Industrial & Scientific: Precision dispensing needles for adhesives, lubricants, or inks, probe needles for testing, fine fluidic channels in instruments, precision oiling needles.
