1. Check the appearance
First of all, it is necessary to check the appearance of the laminating board, and the normal surface of the laminating board should be smooth, without cracks, deformation, bubbles and other defects. Also pay attention to check whether the four corners of the plate are complete, and whether the whole plate has burrs or jagged unevenness.
2. Check the size
Check that the dimensions of the laminated sheet meet the specifications, including length, width, and thickness. Measurements can be made by using tools such as rulers or gages.
3. Check the flatness
The flatness of the laminated board should be checked, that is, whether the surface is flat and whether there is a convex or concave phenomenon. A straight object, such as a steel ruler or a right-angled plate, can be placed on the surface of the laminated board to observe whether there is any obvious misalignment or gap.
Fourth, check the surface quality
The surface quality of the laminated board should be checked to see if it meets the requirements, if there is bad quality decoration, oxidation, stains, wear or scratches, etc., it may affect the service life and appearance of the board.
5. Other examinations
When checking the quality of the laminated board, other related inspections can also be carried out, such as weight check, density check, angle check, etc.
In short, to ensure that the quality of the laminated board meets the requirements, a comprehensive inspection is required. Attention to detail is required to ensure that the results are accurate.
