Design and modelling of fastener system on sand core making shell machine

Abstract Sand core making shell have been considered as a system for metal casting. In the molding of molten casting, the shell machine needs to be fasten using bolts and nuts. The concept of the article discusses bolt’s strength using analytical methods and numerical calculations of materials and dimensional variations. The size and load received by the mold on the automatic sand casting machine normally 1000 kPa. Sand casting mold have dimension around 470 × 415 × 550 mm. Thus, the proposed clamped by 4 hardened hexagonal bolts. Our study provides understanding for the design and numerical modelling of fastener system for the mold clamping of metal casting.
