The parallelism and flatness of the hot plate of the LAUFFER laminator: This part is related to the uniformity of the pressure distribution during lamination. Generally, the machine should be regularly calibrated.The methods of LAUFFER laminator correction are:

1.LAUFFER laminator lead bar (block)-the thickness difference of the lead bar after pressing should be ± 0.1mm

2. LAUFFER laminator pressure-sensitive paper-is a convenient pressure distribution test method, put the pressure-sensitive paper in the opening of the hot press under the condition of cold machine, and then test with 25 ~ 30kg / cm2 pressure, borrow From the color distribution of the pressure-sensitive paper after the test, we can know the pressure distribution of the machine when it is pressed.

 

LAUFFER Laminating Machine Insulation Board Management-It is the asbestos separator on the upper and lower edges of the hot press machine, which may break after a period of use, so it is recommended to replace it once a year.

 

LAUFFER laminator carrier tray management-the focus is on flatness and cleanliness to avoid poor quality after lamination.

 

Use of buffer material for LAUFFER laminator-The purpose of buffer material is to distribute the pressure evenly to each part of the platen. The current buffer material used is mostly kraft paper, with a basis weight of 156 ~ 160g / m2. The best results can be obtained by using it, but under consideration of cost, the number of uses should still not exceed 2 times, because the kraft paper cushioning effect after pressing will be reduced, of course, it will affect the pressure distribution of pressing, and some manufacturers also use cushioning pads To replace kraft paper, it can be reused, but after a certain number of uses, its cushioning effect will also deteriorate.Therefore, how to control an appropriate number of uses is the focus of using this material.

 

Due to the fact that the size and area of ​​the lamination are not fixed during the lamination of the multilayer board, and there are even mixed pressures of different sizes, the platen equipment may produce local differences after long-term use, so the calibration of the press and the buffer material The selection should be more rigorous than the substrate factory in order to obtain better press quality.
