500kg High Strength Rotational Molding Steel Mold For Industrial Storage

Product Overview

For 0.5T and above tank production, the focus shifts from forming capability to long-term durability and structural stability

PT500 improves load-bearing performance while maintaining uniform wall thickness, making it suitable for industrial storage and engineering applications where reliability is critical

Problem

In 0.5T tank applications, issues often appear during actual use rather than during production

Side walls may bulge when the tank is fully filled
Bottom may deform under long-term load
Inconsistent thickness between batches
Deformation may occur during transport or installation

These issues become more significant at medium capacity and can increase maintenance and replacement costs

Solution

PT500 improves stability through structural reinforcement and process optimization

Optimized structure ratio enhances load-bearing capacity
Steel mold improves heat transfer for uniform material distribution
Reinforced bottom and side wall design reduces deformation risk
Optimized opening structure minimizes stress concentration
Compatible with gas and electric heating as well as air and water cooling

Result is stronger structure stable forming and reliable batch production

Specifications

Application

Industrial liquid storage
Agricultural irrigation tanks
Engineering storage systems
Standardized medium capacity tank production

Suitable for applications requiring structural strength and long-term stability

How To Choose

Use the following criteria to make a direct decision

Selection by usage duration
If the tank is used for long-term storage more than 6 months
Choose PT500
If for short-term use
PT300 may be sufficient

Selection by load condition
If the tank operates at 80 percent to 100 percent capacity regularly
PT500 is required
If below 50 percent capacity
PT300 is acceptable

Selection by environment
If used outdoors or under high temperature exposure
PT500 is recommended
If used indoors
PT300 is acceptable

Selection by production stage
If production has entered stable batch stage
PT500 should be the standard model
If still in trial or small batch
PT200 or PT300 may be used

Selection by existing problems
If you already experience
Bulging tanks
Bottom deformation
Transport damage
Strength reduction over time

Upgrade directly to PT500

Conclusion

If your goal is not only to produce tanks but to ensure long-term structural stability and reliability in real use PT500 is the more suitable industrial level solution
