Typical Design Of Lost Form Casting Workshop

Lost foam casting (LFC) process is an importantly evolutive orientation of casting technology, which has considerable attention and development at home in recent years, which was first choice of technical ameliorate in the medium and miniature business enterprise. However, the domestic lost foam casting enterprises have some ubiquity problems compare to overseas lost foam casting enterprises: the casting was baddish and the enterprise scale was small and the production line was simple and crude and the environment bad and production line automation degree and produce the efficiencies are all very low etc. The territorial center of lost foam casting foundries have been built up and the representative factory of the lost foam casting of our country is an important topic. In the paper, based on the design of one lost foam casting company in Beijing we obtained feasible automatic production line of shut wreath design mode of the lost foam casting.With the industry development the styrene plastics (EPS) were used in the entity model at the beginning of in 80's last century. The dry sand was used to make the shape material without adhesive. The sand box was sealed completely with the plastics thin film and recur to take out the vacuum to obtain casting, the domestic is called" EPS-V" method at first, now general call as" EPC" method or call as gasify mold casts the method. Lost foam casting can produce neat, complex combination castings and according with environment protection requirement, which...
