Brief introduction of low pressure casting

The rudiment of low-pressure casting can be traced back to the beginning of last century. The application of aluminum alloy was 19 17 in France and 1924 in Germany, but it did not form large-scale industrial production. Commercial production began after World War II 1945. Mr. Louis of England founded Arumascu Company and began to produce rainwater pipes, beer containers and so on. In 1950s, Austria and Germany began to produce cylinder heads. From 65438 to 0958, Zenella Lumutas of the United States used a large number of aluminum alloy castings on the engine parts (cylinder head, box, gearbox) of small cars, and adopted the method of low pressure casting. This event is an indispensable driving force for low-pressure casting, which is still widely used, especially in the automobile industry all over the world. The low-pressure casting method was introduced to China around 1957, but it really attracted the attention of the industry. It was around 1960 that various researches and equipment were introduced. However, this epoch-making process method has broken the common sense in the past, and there is almost no riser, which is completely different from the gravity gold mold casting technology that has been established as "technology", so the response of the industry is relatively cold.
