To introduce the die casting process of machine tool castings
The lost foam casting process first eliminated the sand core and the core manufacturing process, eradicated the casting defects caused by the core making and the lower core, greatly reduced the production of waste products; the lost foam casting technology simplified the sand processing system, and the sand could be reused completely. Eliminating the sand preparation and waste sand processing departments, but also can set a reasonable shape of the riser in a more ideal position, without the constraints of traditional factors such as type and model, reducing the internal defects of the casting .
The lost foam casting process can be applied to other places besides the castings of the box type and the shell type. As the lost foam casting process-like pyrolysis products cause defects such as carbon addition, black slag, etc., in the casting of low carbon steel castings and automobile duct steel security parts requiring high density, the reject rate is still relatively high. . The adaptability to the shape of the casting structure is particularly strong, and the more complex the structure is, the more sand cores that are required to be used in sand casting and the greater the amount of machining, the more prominent the advantages of using lost foam casting technology are. The more significant the benefits are.
The most important thing in the lost foam casting process is to reduce smoke, dust and noise pollution, to improve the working environment of the foundry industry, and to reduce the labor intensity of foundry workers. At the same time, the process operation is also simplified. The technical requirements for operating workers have been greatly reduced.
Casting is the basis of equipment manufacturing. The quality of castings determines the performance and quality of castings, directly affecting the operational level and reliability of equipment. Although China is already a veritable casting country, there is a clear gap between the quality of casting products and the international advanced level. Most product quality indicators have phased gaps and there are fewer imitations and more innovations. The large-scale casting industry of the lost foam molding process has undergone the process of introduction, digestion and absorption and re-innovation in terms of technology, and has accumulated rich technical and professional production experience in all aspects of the process flow.
The outstanding companies in the foundry industry have unique know-how in certain aspects, thus forming their own core competitiveness. Large-scale machine tool casting companies need to constantly accept the challenges of new materials and new processes
