Embodiment Construction
[0032] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.
[0033] like Figure 1 to Figure 10 As shown, the manufacturing method of the folding seat cushion of this embodiment includes the following steps:
[0034] 1. Compound the surface layer film on the surface of the foamed substrate to obtain the composite sheet body 10 to be molded;
[0035] 2. Place the composite sheet 10 in a mold and press to form, to obtain the desired concave-convex surface cushion 1;
[0036] Before step 2, the composite sheet 10 is placed in the oven 2 to be baked and softened, and then the softened composite sheet 10 is placed in a mold for compression molding. Before pressing the body 10, the temperature of the lower molding surface 3 and the upper molding surface 4 of the mold is lowered to less than 50°C; the lower molding surface 3 of the mold is distributed with grid-like regularly arranged arc concave parts 31. ...
