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. People are buying and using low-pressure When casting equipment, we 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, and the staff can set parameter information according to actual needs, so that the efficiency will be very stable in the process of processing metal materials, there will be no boiling and impact, and the production process can also be Avoid waste 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 methods.
When processing materials with a low-pressure casting machine, the forming process is completed by pressure, which can strengthen the compactness of the material, make the performance of the material more stable and reliable, and achieve better application results. Choosing this equipment can also effectively reduce the occurrence of errors. Compared with the past Compared with advanced 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 should 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 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 movable parts of the mold are prone to failure, resulting in damage to the surface of the mold. A cooling temperature control system should be installed on the low temperature casting machine to keep the working 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 gas will also contact the surface of the mold Complex chemical reactions occur, accelerating corrosion and cracking. When the molten metal is filled with gas, it will first expand in the low-pressure area of the cavity. When the gas pressure rises, it will cause an inward explosion, pulling the metal points on the surface of the cavity out, causing damage and cracking due to cavitation.
