Forged Container Bases and Ring Supports are
Structural Components in medium- to large-tonnage extrusion presses, providing
radial and axial load support for containers, cylinders, and extrusion tooling.
Manufactured through
Hot Forging,
Heat Treatment, and rough machining, these components offer excellent torsional strength, dimensional stability, and fatigue resistance for long-term operational loads.
Typical Applications
- Aluminum and copper extrusion presses
- Industrial extrusion containers and support cylinders
- Heavy-duty structural mounting for extrusion lines
Typical Dimensions
| Parameter | Typical Range |
| Outer Diameter (OD) | 300 – 800 mm |
| Thickness / Height | 50 – 200 mm |
| Single Piece Weight | 0.6 – 4 t |
| Geometry | Solid ring, stepped support flange, or block base |
Typical Materials
- 42CrMo / AISI 4140 – Standard high-strength Alloy Steel for structural stability.
- 34CrNiMo6 / AISI 4340 – For higher torsional load or fatigue resistance.
- Optional: 40CrNiMoA, 30CrNiMo8
Illustrations are for reference purposes. Final geometry and specifications are defined by customer-approved engineering requirements.
1， Hot Forging – Dense internal structure and aligned grain flow for torsional and radial strength
2， Heat Treatment – Quenching and tempering for toughness and fatigue resistance
3， Rough Machining (Optional) – Creates reference surfaces and flange dimensions
4， Finish Machining (Optional) – Precise OD, bore, and flatness tolerances up to ±0.01 mm
Mechanical & Functional Characteristics
- High radial and axial load capacity
- Excellent torsional and bending resistance
- Long-term structural stability under repeated extrusion cycles
Inspection & Quality Control
Forged Container Bases and Ring Supports are inspected rigorously to guarantee durability and dimensional accuracy under operational loads. Spectrometry is used to confirm chemical composition, and tensile (and optional impact) tests verify mechanical performance. Ultrasonic inspection ensures internal integrity, while CMM and conventional gauges check all critical dimensions.
