The Metal Casting Operation
When manufacturing by metal casting, pouring refers to the process by which the molten metal is delivered into the mold. It involves its flow through the gating system and into the main cavity (casting itself). Goal: Metal must flow into all regions of the mold, particularly the casting's main cavity, before solidifying.
