Premium stainless steel material provides good rigidity and corrosion resistance, suitable for multiple piercing and sampling scenarios.
Tube outer diameter, total length, back cut angle and tip profile can be fully customized according to customer drawings or samples.
Strict dimensional and visual inspection for each batch, stable batch consistency to meet mass production requirements.

FAQ:

Q1: What stainless steel grades are available for this back cut tip needle?
A1: We mainly supply 304 and 316L stainless steel. 316L is preferred when the needle contacts liquid or biological samples for better anti-corrosion performance.

Q2: What surface finish is used for this back cut tip needle?
A2: We apply standard surface finish Ra0.8-1.0μm for this product. If you have special high polishing requirements, please inform us in advance for separate process evaluation and quotation.

Q3: Can we customize the back cut angle and needle dimensions?
A3: Yes, tube OD, total length, wall thickness and back cut angle are customizable within our processing capacity under ±0.02mm tolerance. Please provide technical drawings for feasibility evaluation.

Q4: How do you control micro burrs on the back cut edge?
A4: After tube cutting and back cut forming, multi-step deburring and cleaning processes are carried out. Each finished needle will be fully inspected to eliminate residual micro burrs.

Q5: Can you provide custom samples? What information needs confirmation before sample production?
A5: Custom samples are available for piercing and sampling performance testing. Before sample order, we need to confirm material grade, dimension parameters, tip requirement and surface finish. Sample cost depends on processing complexity, mass production can start after sample specification confirmation.
