ning, 810005, China Abstract: In order to meet a large market demand for FCD700 camshafts, a study is made on the mass production of FCD700 camshafts. Based on former experiences in camshaft production, a design of the camshaft mould is improved and the melting process, moulding process, and casting process are optimized to control the casting defects. Producing three pieces in a mould has been achieved for FCD700 camshafts on the 2013LP DISA production line. The actual production in workshop showed a stable casting rejection rate and machining rejection rate, stable casting size, and stable process. Viewing from present situation of production, such defects as shrinkage cavity, shrinkage porosity, pores, slag eyes, sand drop, etc. are avoided, so that the rejection rate is reduced and the productivity of FCD700 camshafts is improved.
