What equipment is required for vacuum casting

Mar 05,21

           Machines and devices used to complete the vacuum casting production process. Casting equipment can be divided into different casting process procedures: smelting equipment, such as cupola, induction furnace, electric arc furnace, reverberatory furnace, resistance furnace, crucible furnace, etc.; molten metal processing and pouring equipment, such as vacuum processing equipment, desulfurization equipment , Deterioration treatment equipment, automatic pouring machine, etc.; sand treatment equipment, such as sand mixer, old sand recycling device, etc.; molding core equipment, such as molding machine, sand blasting machine, core shooting machine, etc.; falling sand cleaning equipment, such as throwing Pill machine, electro-hydraulic sand cleaning device, etc.; casting heat treatment equipment, such as high manganese steel water toughness treatment equipment, malleable cast iron heat treatment furnace, etc. According to different modeling methods, it can be divided into: sand casting equipment, investment casting equipment, metal casting equipment, pressure casting equipment, etc.

       The development of casting equipment was relatively late, and it was not until the 1830s that the first truly reliable vibrating molding machine appeared on the market. In 1848, the United States began to adopt centrifugal casting machines. It was not until the 1880s that commercial molding machines were more common.

  In the casting equipment, the molding core equipment has developed the fastest. It has developed from a stand-alone automation to the automation of the entire production line, including the automation of pouring, sand falling, and sand processing systems. The factors that promote the development of casting equipment are first to improve the quality of castings and increase production efficiency, such as vacuum processing equipment and modern molding core making machines. Secondly, some new processes require corresponding equipment, such as high-pressure molding, chemical self-setting sand, and refining outside the furnace.

  The development trend of foundry equipment is that the degree of automation is getting higher and higher, and computers are used for automatic control and adjustment. In order to adapt to the production of multi-variety and small-batch castings, the flexibility of casting equipment is gradually increasing, such as the rapid replacement of mold plates for molding machines, changing the size of the sand box, and adjusting the amount of sand added. Those with loud noises, such as shock-type molding machines and shake-out sand machines, and those that produce secondary pollution, such as hydraulic sand cleaning equipment, will be eliminated or restricted.
