The advantages of lost foam casting technology are more and more obvious, and many small and medium-sized enterprises have been put into operation one after another. Especially in recent years, lost foam casting enterprises have sprung up. This can be clearly realized from the ordering demand of lost foam casting equipment manufacturers.
However, many lost foam casting enterprises dismounted soon after they were put into operation. 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. They do not fully estimate its regularity and complexity and rush to start. As a result, they encounter unexpected problems in actual production, have no mental preparation, have nothing to do with the problems, and get off in a hurry. As a result, it is not only a waste of time, money and energy, but also the loss of the market.
In fact, lost foam casting is a systematic project, which can be used to produce all kinds of castings in theory, and has achieved extensive success in the laboratory. However, due to the widespread use of foam polystyrene (EPS) used in lost foam casting casting models in China, and the special coating technology has not yet formed the technical superiority, and the dry sand vibration technology and the lost foam casting process are also not mature, leading to many early enterprises, especially small and medium-sized enterprises, these knowledge is not yet thorough, so there will be a passive situation of rushing headlong into mass and coaxing. Experts said that the domestic foundry industry still needs to make continuous efforts for better development in the future.
