Precision casting manufacturers teach you how to operate
Let's analyze the characteristics of precision casting with sand molds. Many processing plants that produce gravel should use their expertise to select models and core-making methods with excellent technology. The production line of the old vibrating or vibrating model machine is not enough, the human capital of the employees is large, the noise is large, and there are not many production regulations, it should be updated and transformed gradually. For small and medium-sized castings, the boxless high pressure forming machine production line can be selected for level clinical diagnosis or vertical clinical diagnosis. The solid line modeling design has high production capacity and small area. In the middle part, you can select various production lines of the box-type high pressure forming machine and gas impact forming production lines. According to the requirements of the rapid and high-precision forming production line, the core-making method can be selected: high-efficiency core-making methods such as cold core box, hot core box, shell core, and medium and large quantities of large castings can be considered to be formed by epoxy resin self-hardening sand. core.
Mass production of super-heavy castings is still the key method for manual modeling. The manual model can be accustomed to various complicated regulations more convenient, without a lot of technical equipment. Sodium silicate sand, VRH sand, organic chemical ester sodium silicate sand, dry clay sand, resin sand casting, concrete sand, etc.; for bulk heavy castings, the pit-mouth forming method is low-cost and fast production. Long collapse long collapse molding method is suitable for mass production or production. Although the original project investment of abrasive tools and sandboxes is relatively high, it can compensate from the two aspects of forming work time and product quality.
Forging methods such as low pressure casting, aluminum die casting, and centrifugal casting are only suitable for production because of the relatively expensive machinery and equipment and abrasive tools.
Standard methods should be suitable
For example, they also produce large and medium-sized CNC lathes and other forging products. Generally speaking, they are made of fitness parts, not produced the same look and sandbox, just made up of other processing plants. Different companies have different production standards (including machinery and equipment, venues, employee codes of conduct, etc.). ), production habit and accumulated work experience. According to this standard, we should consider what products are suitable and what products are not suitable (or not possible).
Precision regulations and costs
The forging precision obtained by different precision casting methods is different, and the original project investment and production volume are inconsistent. After all, the economic benefits are also different. Therefore, to ensure more, fast, better, and economical, it should be applied to all fields. A basic cost estimate should be carried out for the selected forging method to clarify the forging method that has high economic benefits and can ensure the forging requirements.
Although the development trend of China's foundry industry is in a difficult period, in the long run, China's precision casting manufacturing industry still has certain expectations. The demand in the market is slowly warming up. In addition, the overall strength of China's foundry industry is strong. I firmly believe that China's foundry industry will definitely get gratifying examination results.
Authoritative experts expressed that to promote the forging technical strength from the source, simulation should be carried out first to promote the accuracy of estimation, improve process management, and increase output rate. Standard problems can be mastered very well, which is not easy to jeopardize the yield rate of mass production. Second, technology transfer and integration. In addition to improving the understanding of independent innovation and the development of development trends, the company's scientific and technological innovation must also improve the high-precision creation of the company's "production, learning, and scientific research." Third, attach importance to the research and development of raw materials and products. Raw materials are the foundation of industrial production, and there was also a lot of work to be done at that time. In the aerospace alloy product manufacturing industry, especially in the heat-resistant alloy manufacturing industry, the scientific research of some new materials and the professionalism of the beneficiation plant must still be improved, and it is not enough. Fourth, attach importance to the development of configuration technology. The first is the technical problem of industrial equipment. For many important industrial equipment, if the first large and medium-sized machinery and equipment are to be clear from the mouth, the scientific research, design and development of precision casting machinery and equipment is very important.
