Press-molded product and method of manufacturing same

摘要

Methods and apparatuses for manufacturing a press-molded product with a preform including a pair of side wall portions (124) and a connecting wall portion (126) are taught. The preform is pressed with a mold (160,170) until at least one wall portion is bent toward a gap within the mold, and a plate thickness is increased at the at least one wall portion and the connecting wall portion by pressing other wall portions.
