304 Stainless Steel Filling/Spray Liquid Needle CNC Milled Metal Components are precision-engineered parts critical to the function of precision dispensing and spraying systems. Manufactured from corrosion-resistant 304 stainless steel via精密CNC milling, these components form the structural and functional core of needles used for灌装 (filling) and喷液 (liquid spraying) in industries ranging from pharmaceuticals to electronics.
The process allows for the creation of complex internal channels, precise orifice geometries, mounting threads, and intricate tip shapes that control fluid dynamics, ensuring accurate, consistent, and reliable droplet formation or stream delivery.
