Analysis And Solutions For The Reasons Why Rotomolded Products Become Soft
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.

Analysis Of The Problem Of PVC Material Not Forming When Used In Rotational Molding Process
## Possible reasons

1. **Material property mismatch**:
- The melting characteristics of PVC do not meet the requirements of rotational molding process
- The melt flow index (MFI) may not be suitable for rotational molding process
- Insufficient thermal stability, decomposition during rotational molding heating process

2. **Process parameter problem**:
- Improper heating temperature (too high leads to decomposition, too low cannot be fully melted)
- Rotation speed mismatch
- Inappropriate cooling rate

3. **Formula problem**:
- Improper selection or dosage of plasticizer
- Insufficient stabilizer or mismatched type
- Lubricant system is not suitable for rotational molding

## Solution suggestion

1. **Material selection**:

2. **Process optimization**:

3. **Formula Adjustment**:

4. **Equipment Check**:

## Test Recommendations

1. Conduct small-scale trials to determine the optimal process window
2. Use differential scanning calorimetry (DSC) to analyze the melting characteristics of PVC
3. Perform rheological tests to evaluate melt behavior

More specific process parameters and material specifications are required to provide more targeted recommendations.

Why Do Rotomolded Products Need To Have Vents?

1. Why are there vents on the surface of rotomolded products?

(1)Rigid process requirements - exhaust is the "lifeline" of rotational molding

(2)The location of the exhaust hole cannot be completely hidden

(3) Air pressure balance during the cooling stage



2.How to reduce the impact of exhaust holes on the surface?
(1)Design optimization

(2) Process improvement

(3)Post-processing
