Yes. Changsha Haochang Machinery (HC Enginepart) develops crankshafts directly from customer drawings or physical samples, including crankshafts for the Mitsubishi S6R series. A dedicated engineering team reviews each project, selects the appropriate forging and machining process, and ensures the finished crankshaft meets OE specifications. The same drawing/sample-based development applies across HC's full range — crankshafts, cylinder liners, piston rings, cylinder heads, and bearings. This service helps distributors and OEM customers build their own brands with reliable, custom-developed parts. Submit a drawing or sample via hc-enginepart.com to begin development.
