In the process of low pressure casting, it can effectively make the metal liquid fill the mold cavity under the effect of pressure, which is also a method of casting. Low pressure casting is used because of its use during the manufacturing process (use )'S pressure is relatively low, so it is called low pressure casting. Low-pressure casting in a sealed crucible, which effectively feeds the molten metal of its compressed air, under the role of gas pressure (role), the device effectively rises along the riser pipe, through its gate Enter the cavity smoothly and effectively maintain the pressure of the gas on the liquid surface in the crucible. The low-pressure casting process standards effectively include pressurization, pouring temperature (temperature), mold filling, mold preheating temperature and product paint (paint), etc.

The product's hydraulic pressure (hydraulic) force refers to the effective metal level Raise to the pressure required by the gate. The rising speed of the liquid metal in the riser needs to be as slow as possible, which is more conducive to the gas discharge in its cavity, and at the same time, it can also prevent the liquid metal from splashing into the gate and filling the pressure Pa refers to the pressure required to raise the molten metal mold to the top of the mold. Non-ferrous metal casting has a large share (sometimes nearly half) in the use of non-ferrous metal materials, forming a large and complex series of casting alloys. . In the process of low-pressure casting, the boosting speed on the molten metal surface is the filling speed. When the molten metal fills the cavity, the pressurization is continued, so that the crystallization of the casting can be effectively solidified ( solidification) is carried out under a certain amount of pressure (role), the pressure at this time is also called crystallization pressure.

Non-ferrous casting is widely used in machinery manufacturing, aviation, automobile, construction and other industries. Steel castings account for a very small share of the use of steel materials. Most steel mills are supplied in the form of steel, so most smelters and processing plants are located in the same place. In low-pressure casting, the greater the crystallization pressure (pressure), the better the product (product) shrinking effect (product), so that the product can get the denser casting structure, but the crystallization increases the pressure to improve the quality of brass gear Suppliers its castings, not in It can be used in any case (Condition). Non-ferrous metal casting has a large share (sometimes nearly half) in the use of non-ferrous metal materials, forming a large and complex series of casting alloys. .
