Differences between primary molding and secondary molding of multilayer boards

In the process of purchasing multi-layer boards, many consumers do not understand the primary and secondary molding processes of multi-layer board manufacturers. The so-called primary and secondary molding refers to the number of times of hot presses. What is the difference?
The so-called one-shot molding is a plate that has been directly formed by only one hot pressing. The secondary molding is to first form the substrate, then sanding, polishing, and putting the putty on the bottom plate, grinding, then laminating the paper, and then entering the hot press film. . Generally speaking, the differences are mainly related to factors such as product smoothness, flatness, different brightness and different times of use, different glue strength, cost and price/performance difference.
Therefore, the multi-layer board manufacturer has a much different brightness and flatness than the secondary forming board, and the surface is smooth, there will be no potholes, no cracking, no unevenness, no deformation; the bonding force of the secondary molding is far greater. For one-time forming of the board.
