Gating and risering methods are assigned by the Foundry Engineer and applied in the pattern shop before the pattern is released into the foundry. New patterns and new methods are subject to trial before quantity production and trial castings are evaluated by visual and NDT methods to ensure that acceptable soundness is achieved by the method. Production moulds are inspected for cleanliness and integrity prior to closure. Castings are visually inspected and NDT as specified, with records of procedures being fully documented.
A computer originated job sheet and Inspection Test Plan guides the work through the plant and lists instructions to the various departments. As dictated by the customer the job sheet and Inspection test plan are compiled from the customers specifications and the Quality Assurance Department.
