Product Advantages:

Medical-grade stainless steel tubing, excellent biocompatibility, reliable corrosion resistance.

Precision tri-facet pencil tip, smooth penetration and minimal tissue trauma.

Middle sandblasted surface, improves friction performance and anti-slip positioning.

Fully deburred inner and outer walls, prevents tissue scraping and blockage.

FAQ:

What performance benefits does the tri-facet pencil tip bring compared to ordinary single bevel needles?
The three-facet tip creates balanced cutting force during puncturing, enabling smoother penetration with less resistance. It reduces tearing to surrounding tissue and improves stability during sampling or injection operations.

Why adopt partial middle sandblasting instead of full surface treatment?
The sandblasted middle section provides moderate friction to prevent sliding during operation, while the tip and end sections remain smooth to avoid damaging tissue and facilitate assembly with matching components.

Can I adjust the sandblasting area, roughness and tip angle according to my drawings?
Yes, we fully support customized processing. We can control the length of the sandblasted zone, surface roughness value, tri-facet angle, needle outer diameter and tube wall thickness strictly following your technical requirements.

What stainless steel materials are available for this tri-facet pencil point needle?
We offer SUS304 and SUS316L stainless steel. SUS316L delivers stronger corrosion resistance, making it more suitable for scenarios involving long-term contact with body fluids or chemical solutions.

Are all edges processed to remove burrs after tip grinding and surface treatment?
We conduct internal and external deburring and polishing after all machining steps. Sharp residual edges are eliminated to avoid scratching tissue and avoid residual contaminants accumulating inside the needle lumen.
