Heavy-Duty Carbon Steel Spinning (Multi-Step Conical Structures)
Application – Structural Cones for Harsh & Low-Temperature Environments
Engineered for heavy-duty conical components, this solution is ideal for energy, mining, pressure systems, and industrial equipment requiring high strength, impact toughness, and precise stacking geometry.
Advanced Forming – Multi-Diameter Step Spinning
Utilizes integral step spinning with variable diameters to produce complex multi-layer stepped cones in a single forming workflow.
Capable of handling 19-step geometry (Ø585 → Ø342) without repeated tooling changes.
Process Advantages:
- Flexible manufacturing via shared tooling + parameter tuning
- Eliminates frequent die changes for multi-size production
- Controls springback and cracking in high-strength carbon steel
- Ensures consistent geometry across all stepped layers
Precision Control for Multi-Layer Alignment
Designed for stacked structural assemblies requiring strict alignment:
- Hole position tolerance: ±0.05 mm (CNC indexed machining)
- Step geometry: tightly controlled for 19-layer stacking accuracy
- Prevents misalignment in assembly and load-bearing deviation
Surface Finish – Industrial-Grade Consistency
- Full sandblasting (internal & external)
- Uniform surface roughness: Ra 6.3
- Free of oxide scale, rust, and machining defects
- Clean internal cavity, ready for assembly or coating
Material Expertise – Q355D Low-Temperature Steel
Specialized in Q355D high-strength structural steel, delivering:
- Excellent toughness at -20°C low-temperature conditions
- Stable mechanical performance under impact loads
