Hard-walled plastic resin products consist of a sandwich structure in which a dense surface and a microcellular core form the structure for optimum strength, lightness, stiffness and strength / weight property. In the same design, the strengths of the wall can be varied between 6 and 30 mm and still avoid the suction marks formed on the outer surface. In the process, traditional materials such as wood or metal can be planted in the process.
