Circuit

Circuit is a designation for cast recycling materials from the foundry’s own production. These may be sprues, risers or connectors. In some businesses, rejects are incorrectly counted as part of the circuit, although this is not advisable from a commercial standpoint. In the case of rejects, a distinction must be made between direct casting rejects from the mould, casting faults following cleaning, faults following mechanical processing and faults following annealing. With the aid of suitable measures, these individual faults can be minimised, and costs reduced significantly.
