Product details
1. Material and Composition
The primary material used in the V3 Infusion Needle is Stainless Steel 304. This material is renowned for its excellent corrosion resistance, high strength, and ease of fabrication. The needle comprises a hexagonal base and a two-hole needle tip, seamlessly combined using advanced laser welding technology.
2. Design Features
The design of the V3 Infusion Needle includes several key features that enhance its functionality:
Hexagonal Base: The fully threaded hexagonal base, conforming to the thread form per ASME b1.21M, guarantees a secure and stable attachment to the infusion machine. This design optimizes holding pressure, evenly distributing it along the bolt's length, with the highest pressure concentrated at the head where it fastens to the material.
Two-Hole Needle Tip: The needle tip is designed with two corresponding small holes, which facilitate precise and controlled injection of liquids. This feature ensures that the infusion process is efficient and consistent, contributing to high-quality end products.
3. Processing Technology
The heart of V3 Infusion Needle crafting process lies tube swaging, a technique that shapes the needle tip with unmatched precision. We employ two-die rotary swaging machines to meticulously form stainless steel material, ensuring each needle meets exact dimensions and geometry. This meticulous process guarantees uniformity across all needles, laying the groundwork for top-notch performance in infusion tasks.
Meanwhile, the hexagonal base undergoes Sliding Headstock Lathe machining, a precise operation carried out using the esteemed Citizen Cincom L12-1M7 from Japan. With an impressive accuracy of +/- 0.01mm and angular tolerance of +/- 0.1°, this machining process ensures our needles fit perfectly and function flawlessly within infusion machines.
Once the base processing is completed, it is laser marked for the word "V3". The components are then assembled and welded using advanced laser welding technology. By harnessing highly concentrated heat, laser welding creates precise fusion between parts, minimizing distortion and ensuring structural integrity. This method also minimizes heat transfer into surrounding material, preserving the properties of our stainless steel alloy.
Following assembly and welding, the needle undergoes electrolytic polishing in line with ASTM B912 standards. This process removes surface imperfections like burrs and microcracks while enhancing corrosion resistance. Electropolishing, known for its microscopically precise material removal, leaves needles with a smooth, flawless finish, ready for rigorous infusion tasks.
After electrolytic polishing, the needles undergo passivation. Passivated stainless steel resists rust, making it a widely-used metal finishing process to prevent corrosion. The passivation process involves treating the stainless steel with nitric acid or citric acid to remove free iron from the surface. This chemical treatment creates a protective oxide layer, or passivation film, that significantly reduces the likelihood of chemical reactions with air that cause corrosion.
Next, the products receive thorough ultrasonic cleaning to eliminate any remaining contaminants. With up to 40 thousand sound pulses per second, our ultrasonic cleaners provide unparalleled cleaning action, ensuring the highest level of cleanliness and hygiene for customer.
Lastly, each needle undergoes rigorous quality testing to verify its performance and adherence to specifications. From dimensional accuracy to functional integrity, every needle undergoes meticulous scrutiny, guaranteeing uncompromising quality and reliability.
