304 316L Stainless Steel Capillary Processing Customization
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.
