Core Process

Manufactured using multi-pass power spinning (flow forming) combined with shear spinning (thinning), this container is engineered for large-volume deep cylindrical geometries (180L capacity).

For large diameters exceeding Ø500 mm, the process is optimized to address material flow instability during forming.

This ensures uniform wall thickness distribution and eliminates common defects such as uneven bulging or localized deformation.

The rolled rim (curling edge) enhances structural rigidity, handling safety, and edge durability.

Precision Control

For large-scale cylindrical components, dimensional tolerances are controlled as follows:

Diameter Tolerance: ±0.5 mm
Height Tolerance: ±1 mm

Wall thickness is strictly controlled to ensure uniform load-bearing performance, preventing deformation caused by localized thinning.

Surface Treatment

For SUS304 stainless steel:

Internal surface treated by electropolishing (mirror finish)
Surface roughness: Ra ≤ 0.4 μm
Smooth, dead-zone-free surface to prevent material residue buildup

For 5052 aluminum alloy:

Surface free from flow lines, scratches, and forming marks
Clean and uniform finish suitable for food-grade applications

Material Adaptability

5052 Aluminum Alloy: Lightweight (~22 kg), suitable for food ingredient storage

SUS304 Stainless Steel: Excellent resistance to acidic and alkaline corrosion, ideal for chemical storage

Both materials ensure hygienic performance, structural durability, and long-term operational reliability.
