Abstract: In-Place Cope Molding or “IPCM,” is designed to reduce or eliminate certain inefficiencies present in traditional molding techniques during production of the cope half of a sand mold. IPCM allows the cope half of the mold to be produced on top of the drag half of the mold by use of a separation barrier which supports the sand above the mold cavity in the drag. This method reduces or eliminates parting line flash, and also avoids the need to turn over or otherwise handle the cope, allowing the cope to be made thinner than a traditional cope and allowing for lower material costs.
