Today I will tell you about the convex-concave CNC special-shaped positive and negative pressure blister machine? It doesn’t matter if you don’t understand it like this, so let me follow the editor of Shenzhen Yonghengsheng Blister Machine.
 
         The convex-concave numerical control positive and negative press can produce high-gloss sheets with ideal surface effects. If high-gloss workpieces want to maintain the brightness of the PVC film surface and prevent loss of gloss, the temperature of the PVC film surface must be controlled within 91 degrees. At this temperature, the PVC film will lose its gloss naturally. But at such a low temperature, the PVC film has not been completely softened, and the blister work of the blister machine cannot be completed. Therefore, the equipment needs to apply a relatively large pressure on the PVC film to press the PVC film in a semi-softened state. forming. But because the heat comes from above, the temperature at the edge of the workpiece will be lower.
 
         After adding "heating under the workbench", the temperature of the workbench can be used to promote the softening of the PVC film at the edge of the workpiece to achieve a perfect edge finishing effect. At the same time, because the vacuum suction plastic is heat-activated glue, heat is needed to activate the adhesion. At present, the glue used in China generally has two kinds of 60 degrees (single component) and 80 degrees (two components). In order to ensure quality, it is recommended to use two-component glue with a degree of 80 degrees to make the workpiece, so the temperature at the edge of the workpiece must not be too low. So the temperature range is between 80 degrees and 91 degrees. Heating under the workbench can be assisted.
