Butt Welding of Needle Body and Joint of Puncture Needle – seamless laser bonding for medical needle components
Butt Welding of Needle Body and Joint of Puncture Needle is a high-precision laser welding process engineered to join the body and joint of puncture needles with seamless strength. Using advanced laser-beam welding, it delivers welds with spot diameters under Ø200 µm, ensuring smooth, clean finishes and highly reliable performance. Ideal for medical needles, surgical applications, and equipment requiring strict standards of precision and biocompatibility.
Key features:
- Welding spot diameter: < Ø200 µm for ultra-fine, practically invisible welds
- Smooth finish: no deformation, bumps, or discoloration
- Pneumatic automatic control: precise clamping and stable alignment during welding
- Material versatility: compatible with stainless steel, nickel-titanium, platinum-iridium, tantalum, cobalt-base alloys, aluminum, copper
- Process programming: 2D and 2.5D CAM software for repeatable path programming and process consistency
Certification and Standards:
Manufactured under international medical device regulation requirements; the process maintains high precision for biocompatibility, full traceability, and laser safety suitable for surgical instruments and implantable needle components.
Stainless Steel SUS304:
Medical-grade SUS304 stainless steel (austenitic chromium-nickel alloy), offering excellent corrosion resistance and mechanical properties.
- التوافق الحيوي: Low risk of allergic reactions or toxicity, ideal for direct tissue contact in medical procedures.
- Mechanical Properties: High tensile strength (approximately 505 MPa) and elongation (up to 40%), providing flexibility without brittleness.
- Surface Finish: Laser-machined for smooth, burr-free edges, reducing the potential for tissue trauma or contamination.
- Thermal Stability: Maintains integrity across a wide temperature range, suitable for sterilization processes like autoclaving.
Platinum-Iridium:
Platinum-Iridium is a biocompatible, corrosion-resistant alloy with exceptional durability and conductivity. Ideal for precision laser welding, it ensures strong, smooth joints for critical medical components like stone basket heads.
Cobalt Base:
Cobalt Base alloys are highly durable, corrosion-resistant materials with excellent strength and biocompatibility. Perfect for precision laser welding, they provide robust, smooth welds for medical components like stone retrieval baskets.
Nickel-Titanium alloy:
النيتينول (NiTi)، وهو سبيكة من النيكل والتيتانيوم، مشهور بمرونته الفائقة وذاكرته الشكلية، مما يجعله رائدًا في التطبيقات الطبية. بفضل قوة شد تصل إلى 1200 ميجا باسكال ومعامل مرونة يتراوح بين 40 و75 جيجا باسكال، يتفوق النيتينول في البيئات الصعبة.
Aluminum alloy:
Aluminum Alloys are lightweight, medical-grade materials valued for their excellent corrosion resistance and high strength-to-weight ratio. With tensile strength typically ranging from 200–600 MPa and good ductility, they offer durability for medical and industrial applications. Their biocompatibility supports use in non-implantable devices and components. Laser-machined for smooth, burr-free surfaces, they minimize contamination risks and ensure compatibility with sterilization processes.
