Custom Stainless Steel Nozzle Fabrication & Machining Capabilities

Xiamen Dazao Machinery specializes in high-precision CNC machined stainless steel nozzles designed for critical fluid control applications. By utilizing 5-axis CNC milling and Swiss-type turning, we eliminate the structural weaknesses and surface porosity common in cast nozzles. Our process ensures a mirror-like internal finish, which is essential for preventing turbulence and clogging in high-pressure spray systems.

FAQs

01.What are the advantages of CNC machined nozzles over cast nozzles?

CNC machined nozzles offer superior dimensional stability, zero internal porosity, and tighter tolerances (±0.005mm). This results in more accurate spray patterns, higher pressure resistance, and a longer service life in corrosive environments compared to casting.

02.Which stainless steel grade is best for high-pressure nozzles?

For general corrosion resistance, SS304 is standard. However, for marine or chemical applications, SS316L is preferred due to its molybdenum content. For abrasive fluids, we recommend hardened grades like 17-4 PH or 440C.

03.What is the minimum orifice size you can achieve in stainless steel?

Utilizing high-speed Swiss-turning and micro-EDM drilling, we can achieve precision orifices as small as 0.1mm with a tolerance of ±0.002mm and excellent edge sharpness to ensure uniform atomization.

04.Do you provide DFM feedback for custom nozzle designs?

Yes. Every RFQ includes a complimentary Design for Manufacturing (DFM) review. We analyze your 3D CAD files for wall thickness, thread depth, and orifice geometry to optimize production efficiency and reduce costs.

05.Can you match Swagelok or Parker thread standards?

Absolutely. We regularly machine nozzles with NPT, BSPT, and JIC threads that are fully compatible with industry-standard compression fittings, including stainless steel ferrules and manifolds.

06.What surface treatments are available for stainless steel nozzles?

We provide in-house passivation for corrosion resistance, electropolishing for sanitary applications (Ra 0.4), and PVD coating or hardening for wear resistance in abrasive environments.
