What are the design points of low pressure casting machine

     In the process of casting aluminum alloy materials, low-pressure casting machines are often used. At present, this equipment is widely used in the textile industry and automobile manufacturing industry, so low-pressure casting equipment has attracted the attention of many manufacturers and users. When people purchase and use low-pressure casting equipment, they all hope to improve work efficiency, continuously increase output, and create more profits for manufacturers. These are all related to the technical characteristics of equipment selection. So what is unique about the design of low-pressure casting machines?

　　When using a low-pressure Casting Machine for the casting process, the operation method is very flexible. The staff can set the parameter information according to actual needs. In this way, the efficiency will be very stable during the processing of metal materials, and there will be no boiling and impact during the production process. Avoid scrap parts. Therefore, compared with other types of processing equipment, the use of low-pressure casting equipment can effectively make up for the shortcomings of traditional process methods.

 

　　When processing materials with a low-pressure casting machine, the molding process is completed by pressure, which can enhance the density of the material, make the material's performance more stable and reliable, and achieve better application effects. Choosing this kind of equipment can also effectively reduce the occurrence of errors. Compared with previous processing methods, it can effectively control product quality and avoid a large number of unqualified parts due to unreasonable processing methods. Therefore, choosing low-pressure casting equipment can bring many benefits to manufacturers.

 

　　Reasons for mold damage of Low Pressure Casting Machine

 

　　1. Mold temperature: The mold must be preheated to a certain temperature before production. Otherwise, when it is filled with high-temperature metal liquid, it will cool down, causing the temperature gradient inside and outside the mold to increase, forming thermal stress, and causing cracks or even fractures on the surface of the mold. During the production process, the mold temperature rises. When the mold temperature is too high, the moving parts of the mold are prone to failure, resulting in damage to the mold surface. A cooling temperature control system should be installed on the low-temperature casting machine to keep the operating temperature of the crystallizer within a certain range.

 

　　2. The molten metal filled in the low-pressure casting machine is full of high pressure and high speed, which will inevitably cause severe impact and corrosion to the mold, resulting in mechanical stress and thermal stress. During the impact process, molten metal, impurities and gases will also undergo complex chemical reactions with the mold surface, accelerating corrosion and cracking. When the molten metal is filled with gas, it will first expand in the low-pressure area of ​​the mold cavity. When the air pressure increases, it will cause an inward explosion, pulling out the metal points on the surface of the cavity, causing damage and cracking due to cavitation.
