Common Failures and Solutions of Film Applicators

Film Applicators may have some common faults in their work, which affect production efficiency and product mass. The following are some common faults and solutions for Film Applicators:

Uneven film

1. Cause of failure: Unbalanced coating rod or drawdown blade, resulting in uneven thickness of Spreader.
2. Solution: Check the installation of coating rods and drawdown blades, adjust Spreader rollers and drawdown blades to ensure their equilibrating installation.

Second, coating wrinkling

1. Fault cause: substrate fixed uneven or coating rod pressure is not enough.
2. Solution: adjust the position and pressure of the coating rod and pressure roller, if the film substrate is not flat, you can consider using positive Vacuum chuck.

Insufficient or too thick film thickness

1. Cause of failure: Spreader speed does not match, resulting in insufficient or excessive film thickness.
2. Solution: Adjust the Spreader speed to ensure that the thickness of the Spreader meets the requirements.

Film Applicator Stops Working

1. Fault causes: power failure, transmission system failure, etc.
2. Solution: Check the power supply and transmission system to repair malfunctions.

Spreader liquid is insufficient or blocked

1. Fault cause: Spreader liquid shortage or pipe blockage.
2. Solution: Check the Spreader fluid supply system to ensure that the Spreader fluid is sufficient and the pipes are clear.

Film Applicator Noise Excessive

1. Cause of failure: There is a problem with the transmission system or Spreader mechanism.
2. Solution: Check the drivetrain and Spreader mechanism to fix problems and reduce noise.

The above are the common faults and solutions of Film Applicator. Operators should pay attention to regular inspection and maintenance when using Film Applicator, detect and solve faults in time, and ensure the normal operation of Film Applicator.
