Abstract

PURPOSE: To enable total product inspection and perform quality control in a short time without making a molded article unavailable, by molding a practically useless protrusion in one body with the molded article and measuring the destructive strength of said protrusion.
CONSTITUTION: Quality control is performed e.g. by molding a practically useless protrusion 1 in one body with a plastics molding article, destroying said protrusion 1 and measuring the destructive strength or observing the fracture. Further, it is recommended that a generally low strength weld line 4 is made to generate by providing a hole 3 at the end of a protrusion 2 and the destructive strength of said weld line 4 is measured.
