Rotomolded products become soft usually due to improper material selection, poor process control or mismatched use environment**. The following is a detailed analysis of the reasons and solutions:
---
I. The main reasons for the softening of rotomolded products
II. Emergency remedial measures (softening of produced products)
III. Preventive measures (long-term solution)
Summary
The main reasons for the softening of rotomolded products are improper material selection, poor process control or mismatch of use environment. The best solution is:
1. Use high-rigidity resin (HDPE/PP) and add fillers;
2. Optimize heating and cooling processes;
3. Add reinforcement or adjust wall thickness;
4. Adapt to the use environment (temperature resistance/chemical corrosion resistance).
Through system optimization, the hardness of the product can be significantly improved and deformation problems can be avoided.
