Sand casting as a technology has been around for millennia and is selected as a preferred method to produce shaped parts that weigh less than a pound, to very large parts. The process is versatile and cost effective, even for low volume runs because of tooling cost. Nearly any part configuration that can be made using another casting process can be reduced to a pattern and created as a sand casting.
The Yifei Sand Casting Process:
During this molding process, a pattern of the desired finished part including the metal delivery system (gates and risers) is constructed out of hardwood, urethane, metal or foam. Sand containing bonding material to retain its shape is packed around the pattern. The pattern is removed from the bonded sand, leaving a cavity in the mold that is in the shape of the part. Molten liquid metal is poured into the cavity and the metal solidifies. The sand is removed through a shakeout process. Other cast attachments, including the metal delivery system, are trimmed leaving the desired part.
Internal passageways, including intricate structures, can be included in the sand casting process by adding cores. This makes sand casting a popular selection for pump and valve applications. Sand castings would typically be at least partially machined before use.
