Demold the material for 15
To measure the thickness of the inspection material by drilling a number of measurement holes with a drilling tool at intervals such as 0#l+1 pitch, and inserting a measuring tool into each measurement hole. The molding space is inspected indirectly.

業性が悪い問題もある。By the way, as the inspection material injected to measure the molding space, materials with high hardness are used, such as unsaturated polyester resin, which is the same material as the product, and materials in which the resin is mixed with fillers such as glass powder. Therefore, not only is the drilling work with a punching tool troublesome and laborious due to the large number of measurement points being scattered, but also the drilling tool can damage the mold if it is adhered to the mold. The hole must be removed from the mold before the drilling operation is performed to prevent damage to the hole, and there is also the problem that the workability is poor.
