Abstract

PURPOSE: To enhance the accuracy of an inner dimension and to prevent cracks from being generated by providing a slit with a specific depth and a width to an outer side of a folding part.
CONSTITUTION: A deep slit 2 piercing a hard coating is provided to an outer side of a resin plate 1 and the depth (t) of this slit 2 is regulated to 1/4W3/4 of the thickness T of the resin plate 1. Moreover, the width l of the slit at a surface of the resin plate is set to 1/4T tan θ/2≤l when an inner angle of a folded portion is θ. As described above, by enlarging a slit surface relatively, the slit portion can be well heated and the sharp raising having almost no curved surface along a bending line 3 is obtained. Because a resin plate immediately after folded forms a recessed or a protruded part on an outer surface thereof, an outer surface is cut to a desired surface shape after forming.
