If wrinkles appear in the production process of the PVC steel wire hose, the main reasons are as follows:
1. Uneven die temperature
Uneven temperature of the die which will lead to uneven heating of raw materials. The heating ring should be checked to ensure that it is uniformly nested in the die.
2. The cooling effect is not good
The hose is not sufficiently cooled after production, so the cooling water should be cooled thoroughly to reduce the temperature of the cooling water.
3. Improper traction speed
Improper traction speed (either fast or slow) will affect the surface finish degree. For this, the traction speed should be adjusted.
4. The material has impurities
There are impurities in the material, which will lead to defects and wrinkles on the PVC steel wire hose surface. So, the raw material should be replaced.
5. Low temperature of body and parts
If the temperature is too low, the production process will not meet the requirements, which will affect the processing quality. Thus, it is necessary to increase the temperature of the body and components of the die.
