The crankshaft repair technology has been a problem for decades in China. Everyone knows that there are huge business opportunities hidden in this area. Because of the lack of technology, many people who have explored have failed. Now it is composed of seven patents that Mr. Liu Yueji has studied for many years. The crankshaft refurbishment and repair technology completely solves the above problems. The revamped crankshafts of various manufacturers in the world are comparable to the new shafts and offer unlimited business opportunities. We look forward to cooperating with people of insight to create a future. Contact phone URL: http:// "
