How to adjust the embossing machine to solve the problem of excessive edge pressure
Pressure adjustment:
You can start with a lower pressure and gradually increase the pressure until you get a satisfactory embossing effect and the edge indentation is not obvious. For example, the initial pressure can be set to 70% of the current pressure, and increase it by 5% - 10% each time for testing.
Speed adjustment: If the embossing machine presses down too fast, the pressure may be concentrated on the edge of the fabric instantly, resulting in indentation. Appropriately reduce the pressing speed and let the pressure act slowly and evenly on the fabric, which can give the fabric more time to deform and reduce indentation. For example, reduce the original faster pressing speed by 20% - 30%.
Temperature control (if hot embossing):
If a hot embossing machine is used, the temperature must be accurately controlled. Too high a temperature may cause excessive shrinkage of the edge of the fabric to produce indentation. The temperature can be appropriately reduced and the embossing time can be extended to ensure the embossing effect. For example, if the original temperature is 150℃, try to reduce it to 130-140℃, and extend the embossing time by 10-20%.
