Core Metal Spinning Process

Specialized High-Viscosity Metal Spinning Technology

SUS310S (2520) heat-resistant stainless steel exhibits high material viscosity and severe work-hardening characteristics during conventional spinning operations. To overcome common defects such as die galling, surface tearing, and spinning flow marks, a dedicated heavy-duty spinning process was developed specifically for high-temperature alloy forming.

The process integrates:

Dedicated wear-resistant carbide spinning mandrels
Low-temperature flow forming technology
Controlled forming pressure and feed rate
Multi-pass precision spinning sequences
Anti-galling surface stabilization techniques

This optimized process enables stable material flow while preventing surface drag marks and maintaining excellent metallurgical integrity throughout the spinning operation.

Precision Machining & Tolerance Control

Tight Dimensional Stability for Critical Applications

Critical dimensions including outside diameter and overall height are subjected to 100% inline inspection during production.

Precision control capability includes:

Outside Diameter Tolerance: ±0.1mm
Height Tolerance: ±0.2mm
Real-time dimensional verification
Stable concentricity control
Consistent wall geometry after spin forming

The process ensures reliable dimensional repeatability suitable for high-temperature industrial assemblies and precision thermal equipment applications.

Surface Treatment

Mirror-Finish Scratch-Free Surface Processing

To achieve premium cosmetic and functional surface quality, the component undergoes a mirror-grade finishing process with strict appearance inspection standards.

Surface treatment procedures include:

Magnetic polishing
Manual precision refinishing
Surface defect elimination
Non-marking surface protection control
Mirror-finish surface enhancement

Final surface specification:

Surface Roughness: Ra ≤ 0.8μm
No visible spinning lines
No impact marks or surface scratches
Uniform reflective finish

The resulting surface quality is particularly suitable for high-temperature visible assemblies and precision industrial equipment.

Material Capability

SUS310S (2520) Heat-Resistant Stainless Steel

The component is manufactured from SUS310S heat-resistant stainless steel, also known as 2520 stainless steel, which provides excellent oxidation resistance and high-temperature mechanical stability.

Material characteristics include:

Excellent creep strength above 1000°C
Superior oxidation resistance
Outstanding thermal stability
High-temperature structural reliability
Good resistance to thermal fatigue

The optimized spinning process preserves the original high-temperature performance characteristics of the alloy while ensuring excellent forming precision and surface integrity.
