Capacity Selection

Capacity determines mold size, heating cycle and structural requirements

0.2T–1T small tanks
Diameter 530–1040mm, short cycle, high efficiency

1T–5T medium tanks
Diameter 1200–1730mm, balanced strength and performance

5T–30T large tanks
Diameter up to 3150mm, focus on stability and safety

Structure Matching

Structure must scale with size

Above 1500mm diameter requires reinforcement
Above 2500mm height requires support optimization
Above 10T capacity requires segmented mold design

Wall Thickness Strategy

6–8mm for small tanks
8–10mm for medium tanks
10–15mm for large tanks

Thicker walls increase strength but also increase cycle time

Machine Compatibility

Large molds require large machines

3000mm diameter requires high-capacity equipment
Tall molds require sufficient oven space
Heavy molds require load verification

Process Parameters

Temperature control within ±2°C
Rotation speed 3–6 rpm
Heating time 40–60 minutes

Customization Strategy

Custom openings, flanges and dimensions
Reinforced structures for industrial use
Design adjustments based on transport limits

Application-Based Decision

Agriculture focuses on cost and durability
Industrial use focuses on strength
Chemical use focuses on safety

Risk Control

Key risks include deformation, uneven thickness and machine mismatch

Conclusion

Mold selection is a system decision

Capacity defines size
Size defines structure
Structure defines process
Process defines quality
