IPC: B29C33/42
Filed: 1989-02-27
Abstract: PURPOSE:To contrive to enhance the strength of a molded item by shifting the position of weld by a method wherein a shape, in which the volumes of a left and a right mounting parts partitioned by the center line of a through hole or recess are made different from each other by the specified value or more, is produced. CONSTITUTION:When an item molded out of sheet molding compound, which is prepared by mixing glass fibers with thermosetting resin, is intended to be produced in a shape having a through hole 2 or a recess for mounting at its mounting part 1 or the like, a shape, in which the volumes of a left and a right mounting parts partitioned by the center line of said through hole 2 or recess are different from each other by 5% or more, is produced.

For example, the angles of corner (r) and R are set to be 40 deg., x:y is made to be 3:4 (or (x) is made to be 84mm and (y) is made to be 112mm), (z) is made to be 40mm, the through hole 2 is made top be a circle having a diameter of 20mm at the middle of the dimension (z) and the wall thickness of the mounting part is made to be 4mm.
