There are several different processing methods for EVA lining processing;

One is stamping: the stamped eva lining is made with a die and a small stamping machine. If the thickness of the product exceeds 3CM, the four sides may feel concave and convex, and there will be this phenomenon at the position where there are holes on the surface. In addition, the thickness of the stamped product cannot be too thick. If it is too thick, it will make it look ugly and the position where there are holes will feel concave.

Another is carving: the edge of the integrally carved eva lining is straight. If the thickness of the eva lining is 9CM, the four edges can be carved straight, but if it is stamped by a machine, the thickness of 9CM needs to be glued together with two to three layers.

Another is injection molding: this method is rarely used. On the one hand, the mold cost is high, and on the other hand, the molding effect is not very good.
