Product Overview
The 304 Stainless Steel CNC Milled Threaded Spray/Liquid Dispensing Needle is a precision-engineered fluid delivery component manufactured from solid 304 stainless steel using advanced CNC machining techniques. Unlike capillary tubing-based needles, this needle is milled from bar stock, allowing for greater design freedom and structural integrity. It features precision-machined external or internal threads for secure mounting and a meticulously crafted internal channel and tip orifice designed to create specific spray patterns or liquid streams.
Manufacturing Process
  • Material Preparation: Selection of certified 304 stainless steel round bar stock
  • CNC Turning (Primary): Machining the outer profile, shoulders, and preliminary shaping on a CNC lathe
  • Thread Milling/Turning: Precision cutting of external or internal threads for connection
  • Internal Channel Drilling & Shaping: Deep, precise drilling to create the fluid passage
  • Orifice/Nozzle Tip CNC Milling: Critical step using micro-tools to shape the final discharge orifice
  • Deburring & Polishing: Meticulous removal of all internal and external burrs
  • Surface Finishing: Passivation (ASTM A967) standard, with electropolishing available
  • Cleaning, Inspection & Testing: Ultrasonic cleaning with 100% dimensional inspection
Applications
  • Industrial Precision Dispensing: Adhesive/sealant dispensing, lubricant dispensing, ink/paint dispensing
  • Medical Device Manufacturing: Drug delivery systems, surgical instrument irrigation
  • Analytical Instrumentation: Mass spectrometry, chromatography sample injection
  • Fuel Injection & Atomization: Laboratory-scale combustion research, small engine applications
  • Additive Manufacturing: Nozzles for high-resolution material jetting or bioprinting
