The main applications of lost foam casting

The advantages of lost foam casting technology are becoming more and more obvious, and many small and medium-sized enterprises have been put into production. Especially in recent years, lost foam casting companies have sprung up, and this can be clearly experienced from the order demand of lost foam casting equipment manufacturers.
However, there are also many lost foam casting companies that have dismounted soon after they put into production. The reason is that many enterprises do not have a deep understanding of the lost foam casting process, at first it seems that the lost foam casting process is very simple, do not fully estimate its regularity and complexity, rush to the horse, as a result of the actual production encountered unexpected problems, and no psychological preparation, helpless to the problems that appeared, and hurriedly dismounted. The result is a waste of time, money and energy, and a loss of the market, which outweighs the loss. In fact, lost foam casting is a systems engineering that can theoretically be used to produce various castings, and has achieved widespread success in the laboratory. However, because China's lost foam casting model materials generally use foam polystyrene (EPS) for packaging, and the special coating technology has not yet formed a technical advantage, coupled with dry sand vibration technology and lost foam casting process is not mature, resulting in many start-up enterprises, especially small and medium-sized enterprises are not deep understanding of these things, so there will be a passive situation of rushing up and down. Experts said that the domestic foundry industry still needs continuous efforts in order to develop better in the future.
