The valve is closed. At this time, there is a pressure difference between the upper and lower pressure cylinders. Some special metal parts cannot be produced by other production processes. The walls of these metal parts are very thin and the cavity is very deep, because aluminum die-casting is used. For the production of metal parts, we need to melt the raw materials for metal production, and then ensure that the molten metal can maintain high fluidity in a working environment where the pressure is high and the speed is very fast, so that some can be produced. The lower part of the casting device adopts the principle of low pressure casting, and the upper part adopts the principle of autoclave casting. Manufacturer consultation hotline: 0755-28486188-835. Today, the editor of Shenzhen Mould Factory Company briefly analyzed the working principle of differential pressure casting. Because the entire casting process is under pressure, the castings have good compactness and can eliminate casting defects such as porosity, pores and pinholes, thereby improving the strength, air tightness and corrosion resistance of the parts. is a wholly-owned plastic mold company and plastic mold manufacturer integrating mold product development and design, mold manufacturing, injection molding, and oil spray screen printing. The improved differential pressure casting equipment has reached the world advanced level. The company specializes in plastic molds, plastic molds, injection molds, medical supplies molds, instrumentation molds,household furniture molds and other production services company manufacturers in Shenzhen. In this way, as long as the mold is made and the position of the mud core is accurate, the crane places the mold on the riser pipe of the middle partition and covers the pressure cylinder, and the programmed program will lock itself, pressurize automatically, and wait for it. The difference is that the autoclave is inflated and pressurized after pouring, while the differential pressure casting makes the mold at high pressure before pouring. Its main working principle is: the dry compressed air thin wall injection molding body enters the mutually sealed and connected upper and lower pressure cylinders smoothly through the A and B valves at the same time. After pouring, it will automatically maintain the pressure and deflate, and finally obtain a satisfactory casting. With the help of this production technology, we can produce some metal parts with more complicated structures and clear contours. When the pressure in the upper and lower pressure cylinders reaches equilibrium, the upper and lower cylinders are connected to each other.Differential pressure casting is a new process that combines the filling principle of low pressure casting with the crystallization principle of castings in an autoclave.
