The Metal Casting Operation - Manufacturing Process
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. Factors Of Pouring:

Mount Polley - Remediation and recovery journal
Until the end of the Shang Dynasty around 1050 BC, China used the mold casting as the sole copper manufacturing method. In this process, an object is reproduced on a model, which is then cast in clay. Once the model has been released from the mold, the pieces are reassembled, but the mold becomes a casting mold after firing.
