Huizhou Pengchengrui Technology Co., Ltd.

Customized cutting of nickel titanium alloy pipes, with laser cutting (femtosecond/fiber optic) and precision post-processing as the core, can be customized according to outer diameter of 0.18-25mm, wall thickness of 0.025-3mm, length and pattern, with medical grade precision up to ± 0.002mm.

1、 Core customization parameters (can be ordered directly)

Material: binary nickel titanium (Ni54.5-57%), multi-element doping; The phase transition temperature Af can be adjusted from -40 ℃ to 100 ℃.

Specification range

-Outer diameter OD: 0.18-25mm (commonly 0.5-10mm).

-Wall thickness WT: 0.025-3mm, with thin walls up to 0.05mm.

-Length: 0.5-2000mm, tolerance ± 0.01-0.05mm.

Accuracy and Surface

-Diameter tolerance: small pipe ± 0.002mm, large pipe ± 0.01mm.

-Surface roughness: The outer surface Ra is ≤ 0.1 μ m, and the inner hole is clean and free of burrs.

-Straightness: ≤ 0.5mm/m, higher requirements can be negotiated.

Cutting patterns: straight cut, oblique cut, thread, mesh, hollow, bracket/snake bone/endoscope tube and other complex shapes.

2、 Comparison of mainstream cutting techniques

Femtosecond laser (preferred for medical use): No thermal damage, no burrs, accuracy ± 0.005mm, suitable for implantable products such as stents and microcatheters.

Fiber laser (commonly used in industry): high efficiency, low cost, accuracy ± 0.02mm, suitable for structural components and sensor sleeves.

EDM: Thick walled/large tube cutting, suitable for orthopedic implants, with moderate accuracy.

3、 Customized process 

1. Provide drawings/parameters: OD x WT x length, cutting pattern, accuracy, surface requirements, application scenarios (medical/industrial).

2. Material confirmation: Medical grade (ASTM F2063/ISO 13485) or industrial grade, provide material certification.

3. Programming and sampling: Laser programming → First piece sample confirmation .

4. Batch cutting: femtosecond/fiber laser cutting → deburring → cleaning → heat treatment shaping → testing → packaging.

5. Delivery: Provide size reports, material certificates, and appearance inspection reports.

4、 Typical application scenarios

Medical: vascular stents, heart valves, microcatheters, endoscopic snake bone tubes, biopsy needles, orthopedic implants.

Industry: Sensor sleeves, temperature control components, shock absorber springs, precision nozzles, aerospace fittings.
