The selection of stainless steel plate shall consider the operating conditions, such as manual operation or automatic operation, the performance and type of hot pressing, and the quality requirements of pressing materials, such as hardness and gloss. Economic accounting should also be considered. For each newly polished steel plate, the number of times a decorative plate with slow quality can be produced. When selecting the most reasonable steel plate thickness, the service time, quality and stiffness of the steel plate shall be considered, and the strength requirements of the pressure steel plate shall be considered; Thermal conductivity; Pressure distribution and width specification of pressure plate. If the steel plate is not thick enough, it is easy to bend and affect the production of decorative panels. If the thickness is too large and the steel plate is too heavy, it will not only increase the cost of the steel plate, but also bring unnecessary difficulties to the operation.
