More Details
This project focused on producing industrial piping components where material performance and machining accuracy are both critical. The client needed to validate whether duplex stainless steel could meet design requirements without introducing machining risks or assembly inconsistencies.
The main challenges included machining complexity due to the material’s high strength, maintaining tight tolerances across multiple processes, and ensuring interfaces aligned correctly with existing piping systems. We selected a hybrid machining route to control risk while keeping the development timeline predictable.
This solution is well-suited for industrial equipment manufacturers and engineering teams validating critical pipeline components before pilot builds or system-level testing.
Key Features & Advantages
1️⃣Engineering-Driven Process Selection
Duplex stainless steel offers excellent strength and corrosion resistance, but is demanding to machine. We segmented features by function, assigning each to the most suitable process to ensure stability and accuracy.
2️⃣Precision Across Multiple Machining Methods
CNC turning was used for cylindrical and concentric features, CNC milling for complex profiles and interfaces, and wire EDM for precise internal or sharp-corner geometries that are difficult to achieve by conventional cutting.
3️⃣Material Performance Validation
Prototyping in the final-intent material allowed early confirmation of mechanical behavior, surface integrity, and manufacturability under real-world constraints.
4️⃣Controlled Tolerance Management
By managing datum references consistently across milling, turning, and EDM stages, we minimized cumulative error and ensured reliable assembly fit.
5️⃣ Predictable Lead Time
Despite material and process complexity, the full prototype cycle was completed within 15 days, supporting timely engineering decisions.

FAQs
Q1: Why use duplex stainless steel at the prototype stage?
Using the final-intent material helps validate both performance and machinability early, reducing downstream risk.
Q2: Can wire EDM be avoided to reduce cost?
In some cases, yes. However, EDM is often necessary for precision internal features or sharp geometries that CNC milling cannot achieve reliably.
Q3: Do you support small-batch production after prototyping?
Yes. We support pilot runs and small-batch builds with the same controlled process approach.
Q4: How do you handle machining difficulty with duplex stainless steel?
Through optimized cutting strategies, tool selection, and process sequencing tailored to the material’s properties.
Q5: Can you provide DFM feedback during prototyping?
Yes. DFM review is part of our engineering workflow to improve manufacturability and cost efficiency.
