Common Sense of Surface Processing of PVC Foam Board

Now we know a little about the surface processing of PVC foam board. Many people will say at first that they didn’t know it before, but some friends are still unfamiliar with it. Follow the steps of Xiaobian to find out.

The processing characteristics of PVC foam board are roughly the same as those of wood processing. Just avoid work. The temperature is too high to cause scorching. In addition, the chips generated after processing can be collected and recycled to reduce costs.

1. The engraving machine can be used for molding according to the design drawing, and then the surface is selected to be affixed with melamine board or baking varnish; however, it should be noted that if the surface is uneven, only 2 PVC board can be used as the material.

2. Bending molding is only applicable to solid foamed boards, and hollow foamed boards are not suitable. The processing method is to use upper and lower molds, cover the aluminum mold with aluminum plates and heat the solid foamed boards to a plasticizing temperature of 70 to 90 degrees. In the meantime, there is no change in the surface of the shape foamed board directly by using the upper and lower molds.

3.Self-adhesive PVC can be printed with different grains on the surface when extruded and manufactured, which can save unnecessary processing procedures. Introduction of PVC Foam Board Manufacturers 4. Next is the common processing method. The surface is pasted with crystal board, melamine board and melamine paper. On the edge sealing part, the general processing is mostly automatic edge banding machine, and automatic sealing. The edge machine is divided into two types: roller type and crawler type. However, if a hollow foam board is used, a crawler edge banding machine is recommended. It is not easy to cause unevenness after surface edge banding, and the adjustment of pressure is also very important. The color of the foamed board is also recommended to use a color similar to the surface coating material, to avoid obvious color difference when the paper is shrunk after being pasted like melamine paper.
