3-in-1 Core-Blowing Technology

摘要

Equipment Merchants International Inc.'s (EMI) new patented 3-in-1 technology that simplifies the blow, tamp, and curing cycle started with an analysis of core-blowing cycle times, and how to cure a core efficiently. Through experience, EMI has found the cost of manufacturing core machines is directly proportional to the cycle-time or throughput requirements that customers' demand. Not only is the dry cycle important, but the process times related to exhaust, gas, and purge times also directly effect the final throughput of the core system. As foundries consolidate core families into single designs, they require higher-capacity core machines to meet the demand for larger single-piece cores to be blown. This is also the case with newer casting processes gravitating to larger, more integrated, blown-sand packages, such as the precision sand process. These high core machine costs, consisting of floor space, higher utility requirements, and maintenance costs, put the return-on-investment (ROI) for these types of core machine solutions out of the reach for most competitive foundries.
