Impeller This RFQ was sourced on www.MFG.com in USA for Shell Mold Casting This part is an impeller for a blower. It is used to blow air across an airconditioning condenser coil. The impeller is driven by an electric motor. Ideally, the part will be quoted complete including machining and balancing. However, casting-only quotes will be considered. The raw casting will be used to create two seperate finished impellers, each with a different outside diameter. Projected annual usage of this casting is 150/yr. The smaller diameter impeller has been in production for a few years and parts are available for reverse engineering. Additionally, a 3D model of the larger diameter part is available and is posted allong with this RFQ. This part weighs approximately 1.1 lbs.The buyer is having this part quoted in multiple categories in order to determine the most cost effective method of manufacture.

Shell Mold Casting: Shell casting is the process by which sand is mixed with a plastic binder and put into a box. Sand is dropped onto a heated metal pattern to form the casting mold shell. The mold shell may be in two or more pieces depending on the complexity of the part. The various parts of the molding shell are then glued or clamped together, placed in a pouring jacket and stabilized by surrounding the shell-casting mold with shot or sand. Shell casting produces parts that have a good surface finish, with a tight tolerance. Additionally, the production rate for shell casting is higher than with conventional sand molding. Metals typically used in shell casting include cast iron and alloys of aluminum and copper.
