When the molding is completed, the outer mold is moved and released from the inner mold. At this time, the molded body is locked to the outer mold by the projections and is in a state of being attached thereto. The molded body is greatly strained by the shearing force generated between the molded body and the inner mold. Therefore, by increasing the crosslinking time of the molded article and increasing the crosslinking density,
The permanent deformation of the molded article was prevented.

Also, the core wire was greatly distorted on the back surface. This is because the concave / convex pattern region is locked by the outer mold and is not easily deformed, while the flat region is not constrained, so that it is susceptible to large distortion.
