Abstract：

Lost Foam Casting Note: Lost Foam Casting (also known as full mold casting) is to combine paraffin wax or foam models similar to the size and shape of the casting into a model cluster, brushed with refractory coating and dried, then buried in dry quartz sand and vibrated Modeling, pouring under negative pressure to vaporize the model, liquid metal occupies the position of the model, solidification and cooling to form a new casting method.

Abstract：

The history of lost foam casting in China: In 1979, a research group led by Professor Liu Lizhong, a well-known expert in lost foam casting and a researcher at the Changchun Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences, started the principle experiment of lost foam casting for the first time in China. In the same year, Professor Liu Lizhong published the "Three Field Theory of Lost Foam Casting" in the National Society of Foundry Technology, and systematically expounded the characteristics and regularity of this method for the first time in China. In 1982, on the basis of a large number of laboratory experiments, Professor Liu Lizhong presided over the establishment of an experimental production line for lost foam casting in the factory of the Institute of Optics and Mechanics. Professor Liu Lizhong presided over the completion of dozens of lost foam casting production line projects with advanced technology, complete functions, reasonable configuration and efficient production.

Abstract：

V method casting and lost foam casting are also called negative pressure casting, named after the initial "V" of the word "Vacuum" in English. The biggest advantage of it different from traditional sand casting is that it does not use adhesives. V method casting uses plastic film to seal the sand box and extracts the air inside the mold by a vacuum exhaust system. There is a pressure difference between the inside and outside of the mold, which makes the dry sand compact and form For the required cavity, the casting is solidified by core lowering, box mixing, pouring and vacuuming, the negative pressure is relieved, and the casting sand is collapsed to obtain the casting.
