Brief: We show the practical steps and results so you can judge suitability quickly. This video provides a detailed walkthrough of the CNC milling process for 304 Stainless Steel Filling Spray Needles, from material preparation to final inspection. You'll see how complex internal channels and precision orifices are machined, witness the critical deburring and electropolishing stages, and learn how these components ensure reliable performance in precision dispensing applications.
Related Product Features:
  • Precision-engineered from corrosion-resistant 304 stainless steel for durability and chemical compatibility.
  • CNC milling enables creation of complex internal channels and precise orifice geometries for controlled fluid dynamics.
  • Electropolished internal surfaces achieve mirror-like finish (≤0.2 µm Ra) to reduce friction and prevent particle adhesion.
  • Capable of producing orifice diameters from 0.05mm to 2.0mm with tight tolerances of ±0.005mm for critical applications.
  • Designed for high-pressure applications with pressure ratings that can exceed 10,000 psi depending on design specifications.
  • Suitable for pharmaceutical filling, electronics dispensing, adhesive applications, and analytical instrumentation.
  • Undergoes rigorous 100% inspection including dimensional verification and functional flow testing.
  • Full material traceability with mill test certificates available per EN 10204 3.1 standards.
FAQs:
  • What materials are available for these precision filling spray needles?
    The primary material is 304 Stainless Steel (AISI 304, UNS S30400), which offers excellent corrosion resistance for most applications. For environments with harsher chemical exposure, 316L Stainless Steel is available as an alternative material option.
  • What level of precision can be achieved with the orifice diameter?
    These CNC milled needles can achieve orifice diameters ranging from 0.05mm (50µm) to 2.0mm, with typical applications using 0.1mm to 0.5mm ranges. For critical applications, we maintain tight tolerances of ±0.005mm on orifice diameter with concentricity of ≤0.01mm TIR.
  • How are these components cleaned and finished to ensure purity?
    All components undergo electropolishing to create mirror-like internal surfaces with Ra ≤0.2µm, followed by ultrasonic cleaning to remove all processing residues. They are cleaned to high-purity standards equivalent to ISO Class 5/7 particle counts, making them suitable for pharmaceutical and medical applications.
  • What industries typically use these precision filling spray needles?
    These components are critical in pharmaceutical filling systems, electronics manufacturing for solder paste dispensing, industrial adhesive applications, medical device assembly, analytical instrumentation, and aerosol spray systems where precise fluid control is essential.
