Summit brand forged crankshaft
Isn't a lot of infrastructure needed to produce a forged crankshaft, especially the dies? Would a Chinese company invest in this upfront cost for a likely small market (sell 100/yr?). Could some be sourced from OEM stock that was stashed, perhaps raw forgings still needing machining? I once worked at a company which made large valves. The way casting worked is a foundry holds the blanks (wood & leather) and sand-casts more bodies to order, then company would machine those. Similar to how circuit board manufacturing works. If my company didn't pay the storage fees, the blanks were scrapped. Some were ruined by rot while sitting in storage. I'm guessing forging with steel dies works similarly. Perhaps a company can order more raw forgings using the OE dies.
A quick search finds that Molnar crankshafts (post 27) are forged. They only state "finished in U.S.A", so likely forged overseas.
