How to solve the deviation problem of PET silver paper when die-cutting?

To solve the deviation problem in the die-cutting of PET silver paper, you can start from the following aspects:

First, check and optimize the die-cutting equipment and process

1.Equipment calibration and maintenance:

Calibrate the die-cutting machine regularly to ensure the accuracy and stability of the equipment.

Check whether the key components of the die-cutting machine such as the intermittent mechanism and the front and back positioning pendulum are excessively worn or loose, and adjust or replace them in time.

2.Process parameter adjustment:

According to the thickness, hardness and other characteristics of PET silver paper, adjust the die-cutting pressure, speed and other process parameters to ensure that the material is evenly stressed during the die-cutting process and reduce the deviation.

Second, material preparation and processing

1.Material inspection:

Before die cutting, carefully check the quality of PET silver paper, including flatness, dimensional stability, etc., to ensure that the material meets the requirements of die cutting.

2.Pretreatment:

If the PET silver paper needs to be pre-treated (such as corona treatment, special coating, etc.), it should be ensured that the treatment effect is uniform to improve the die-cutting accuracy.

Third, die cutting plate and positioning hole design

1.Die cutting plate production:

The use of high-precision die-cutting technology to ensure that the size and shape of the die-cutting plate are accurate.

According to the characteristics of PET silver paper, select the appropriate die cutting tool type, such as hardness treated blade, to ensure the die cutting effect.

2.Positioning hole design:

Reasonable design of positioning holes on the die cutting plate to ensure accurate alignment in the process of multiple die cutting and reduce deviation.

For multiple composite and die cutting products, special attention should be paid to the positioning hole position and accuracy of each die cutting.

Fourth, operation specifications and training

1.Operation specification:

Formulate detailed die-cutting operating procedures, including equipment operation, material preparation, process parameter setting and other links, to ensure that operators can operate in strict accordance with the procedures.

2.Personnel training:

Regular training of operators, improve their professional skills and responsibility, reduce the die-cutting deviation caused by improper operation.

Fifth, environmental control

1.Temperature and humidity control:

Keep the temperature and humidity of the die-cutting workshop stable to avoid the size change or deformation of PET silver paper due to environmental changes, thus affecting the die-cutting accuracy.

2.Cleanliness control:

Maintain the cleanliness of the die cutting workshop and reduce the impact of dust and impurities on the die cutting process.

Sixth, problem analysis and continuous improvement

1.Deviation problem analysis:

The deviation in the process of die cutting is analyzed in detail to find out the root cause.

2.Continuous improvement:

According to the analysis results, the corresponding improvement measures are taken, such as adjusting the process parameters, replacing the die cutting plate, improving the performance of the equipment, etc., and constantly improving the die cutting accuracy and stability.

In summary, to solve the deviation problem in the die-cutting of PET silver paper, it is necessary to comprehensively consider many aspects such as equipment, materials, process, operation and environment. Through refined management and continuous improvement, can effectively reduce the die-cutting deviation problem, improve product quality and production efficiency.
