Vacuum forming machine vacuum forming 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, vacuum forming degree of thickness of the material itself or material density is uneven, lead to uneven thickness of vacuum forming out of products. 3, vacuum forming, mould depth is too deep, lead to uneven thickness of the product of vacuum forming. 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. Vacuum forming mould that is jun jing sai of vacuum molding machine vacuum forming uneven summarize the causes and solutions, whether chip vacuum forming machine or thick slices vacuum molding machine can be used well, have you learned?
