Vacuum forming machine blister uneven, how to do?

Contact machinery industry knows that, sometimes, vacuum forming machine may appear uneven thickness of the products, this is normal, the key is how are we going to solve? Vacuum molding machine vacuum molding machine appeared phenomenon of uneven thickness, it may be because the following reasons: 1, vacuum molding machine at the time of baking materials, the temperature is not uniform. 2, degree of thickness of the material itself or material density is uneven, lead to uneven thickness of blister products degrees. 3, blister, mould depth is too deep, lead to uneven thickness of blister products. So, we can adopt the method of how to avoid? 1, the evenness of temperature heating vacuum molding machine in softening materials. 2, when buying material, guarantee is the same material, have the same degree of thickness. 3, in the mold before adsorption, an upper die, the top once again. Blister mould that is jun fine uneven game of vacuum molding machine blister summarize the causes and solutions, whether chip vacuum forming machine or thick slices vacuum molding machine can be used well, have you learned?
