I. First, determine the four key parameters (which dictate the machine model size)
1) Pipe Diameter (D) \u00d7 Wall Thickness (T) (Most important)
Model designations are typically based on the maximum pipe diameter:
DW38 \/ 50 \/ 63 \/ 75 \/ 89 \/ 114 \/ 130
Rules of thumb (carbon steel, ambient temperature, R \u2265 2D):
\u03a610\u201330: Choose DW38 model (30\u00d72.0)
\u03a630\u201340: Choose DW50 model (40\u00d72.0)
\u03a640\u201350: Choose DW63 model<\/p>\n\n\n\n

Impact of wall thickness:
T \u2264 2mm (thin-walled): Must use a mandrel + wiper die; otherwise, flattening or wrinkling occurs.
T \u2265 5mm (thick-walled): Choose hydraulic or high-torque servo drive; requires higher power.
<\/p>\n\n\n\n

2) Material (Determines power requirements and tooling)
Aluminum \/ Copper: Soft, low springback \u2192 Servo-electric or small hydraulic machines suffice.
Carbon Steel: Medium hardness \u2192 Standard hydraulic or NC machines.
Stainless Steel \/ Titanium: Hard, high springback (6\u00b0\u20138\u00b0) \u2192 Servo CNC + springback compensation + alloy steel tooling.
<\/p>\n\n\n\n

3) Bending Radius (R) (The core challenge)
R \u2265 2D: Easily handled by standard models.
1.5D \u2264 R < 2D: Requires mandrel + wiper die; CNC offers greater stability.
R < 1.5D (small radius): Requires a booster bending machine (with side-push function); otherwise, the inner wall wrinkles and the outer wall tears.
<\/p>\n\n\n\n

4) Bending Angle and Shape
Single-plane bending (one direction only): 2-axis NC is sufficient.
Multi-angle spatial bending (3D): 3-axis or 5-axis CNC; allows for one-shot forming without repeated clamping.<\/p>\n\n\n\n
