The processes are very expensive when it comes to tooling and the capital expenditure required. Another related procedure is superplastic forming SPF. All pieces are operator-inspected at every step in the manufacturing procedure, and at final inspection. Superior results are likewise being achieved by hot blow-forming, where the sheet-metal blank is coerced into the Plastic Injection Mold below the pressure of argon fed under microprocessor control to keep the proper strain-rate.
