Before casting,the top and/or bottom layer materials can be processed for the purposes of embossing,corrugating or other necessary treatments either on the line or off the line,depending on the materials of the top and/or bottom layers and their shapes.

• 根据面层材料的不同和面层外形的差异，在浇注前，面层材料将在生产线上或线外进行压印，轧瓦楞或其它必要的处理。
