The paper tray manufacturer's wet-pressed paper tray product surface is smoother and smoother, and it is an obviously outstanding craft product in terms of quality. At present, it has received the favor of many products. The paper tray manufacturer will share with you the common problems and solutions of the wet-pressed paper tray process!
Hot-pressed mesh fracturing:
In the process of hot pressing, it is often encountered that the mesh is ruptured. If a fracturing mesh is attached to the mold, and then the product is placed on the mold for hot pressing, the pressed paper support product will leave a trace, which will affect the Exterior. The solution is to change to a softer mesh. Before pressing the mesh, manually pour the mesh into the product shape as much as possible. If the mesh cannot be pressed well, you can use a spot welder to fill up the crack of the mesh!
Texture printing on the surface of the paper holder:
There are lines on the surface of the wet-pressed paper support products after hot pressing. These lines are mainly caused by the uneven suction of the molding die. The solution is to use a smaller drill bit for drilling, and you can increase the hot pressing. Machine pressure, which can effectively improve the texture phenomenon. If feasible, you can also add several layers of mesh film on the forming mold, which can well disperse the vacuum force at the punching place!
Product blackening:
Blackening of the paper support is a very common problem, mainly because the smaller part of the product structure is easy to be smeared during molding, so the thickness is larger than other parts, and it is pressed too tightly during hot pressing and turns black. It may also be caused by the pressure of the hot press itself being too high and the hot pressing time being too long. For the above situation, you only need to use a file or remove the mold corresponding to the blackened place on the machine tool. In another situation, you need to adjust the pressure and time of the hot press at the same time to make the machine reach a balance point!
