STEP 11:
Parts are cut out from the sprue using one of several cut-off techniques we employ, through the gate that was holding the casting to the sprue. The gates are lightly ground, and the castings proceed to final surface treatments such as shot blasting, sand or oxide blasting, or other treatments. In cases where heat number traceability is required, we etch the serialized numbers onto each casting. Following any applicable heat treatment, NDT testing, machining, or other certification testing required, the castings are 100% inspected and prepared for shipment to our customers.
