SeAH GSI Technology Advantage
Piercing vs Extrusion (5000T)
Piercing
Shearing forces increase internal tensile stress, which results in material cracking.
Extrusion
Compression force promotes uniform material formation without cracking, resulting in a defect-free, fine grain structure.
5,000-Ton Hot Extrusion Technology
Technical Comparison Overview
| Category | Conventional Manufacturing | SeAH GSI – 5,000-Ton Hot Extrusion |
|---|---|---|
| Process Design | General-purpose process | Process optimized specifically for stainless steel |
| Extrusion Force | Limited forming capacity | 5,000-ton high-force extrusion capability |
| Billet Preparation | Standard billet conditioning | Strict billet control for high-integrity extrusion |
| Heating Control | Relatively broad temperature range | Precisely controlled heating for stable metal flow |
| Lubrication Control | Conventional lubrication | Optimized lubrication for stable metal flow and die life |
| Deformation Time | Longer deformation time | Short-time, high-pressure deformation |
| Dimensional Accuracy | Greater wall thickness variation | Excellent dimensional uniformity |
| Surface Quality | Inconsistent surface finish | Smooth surface and reduced defect risk |
| Mechanical Properties | Batch-to-batch variation | Consistent mechanical performance |
| Application Suitability | General industrial use | High-demand energy, petrochemical, and industrial applications |
The 5,000-ton hot extrusion process delivers superior dimensional accuracy, enhanced structural integrity, and consistent high-quality performance—exceeding the limits of conventional manufacturing.
