With the continuous development of the manufacturing industry, the Investment Casting process is also developing rapidly. In fact, precision investment casting was developed on the basis of ancient wax casting. In China, the real practical application of investment casting should be considered in the 1940s. Due to the development of the aerospace industry at that time, the blades, impellers, nozzles, etc. of aero-engines were complicated in shape and extremely difficult to process, and the dimensional accuracy and The surface finish has high requirements, which are difficult to achieve with ordinary precision CNC Machining, and the cost is extremely high. Therefore, a new precision molding process needs to be found to meet its requirements. At this time, after the improvement of materials and processes, The modern investment casting is improved and perfected on the basis of the crafts handed down in ancient times, which also creates favorable conditions for the aviation industry to further improve the performance. In the 1950s and 1960s, Investment Casting Parts were slowly used in industrial production. After that, this advanced casting process has been greatly developed, successively in aviation, automobiles, machine tools, ships, internal combustion engines, steam turbines, telecommunications equipment, cutting tools, and It is widely used in medical equipment and other industries. In this way, stainless steel castings, alloy steel castings, carbon steel castings, etc. are widely used in manufacturing. It is also used in the casting of arts and crafts, such as brass castings and so on.

In the past ten years, investment casting has been developing at a relatively high speed. The world's major industrial countries increase at an average rate of 7% to 12%, and special-purpose castings will increase at an alarming rate of 30%, which promotes the development of investment casting wax development technology. China has also experienced rapid development in the past two decades. Because of its rapid development, it has also led to uneven investment casting manufacturers and strange quality. After continuous development, the competition is getting bigger and bigger, and it is necessary for the foundry to continuously improve and perfect the processing technology, as well as to improve the subsequent secondary processing capabilities and services. The foundries that can survive now are constantly seeking improvement in technology, automation, and intelligence to adapt to the development of society.

The following picture shows a 316 stainless steel investment casting parts by SCZY. It is used in marine projects. It not only has high requirements for resistance to seawater corrosion and strength, but also has high requirements for assembly and appearance use. According to the traditional investment casting process, there is no way to directly meet the requirements, and it is not a problem for our manufacturers with very rich experience in metal casting and precision metal machining. We can provide follow-up services according to customer requirements. Therefore, after the product is formed, we need to reshape the product, and then CNC turning the two ends with tolerance (assembly requirements) to ensure accuracy. It is also necessary to manually polish the surface of the middle part that requires a mirror surface to achieve the best effect. Finally, after our continuous efforts, customers received qualified and satisfactory products.

SCZY has been advancing in investment casting and precision machining, as well as subsequent supporting services. If you are interested in learning more about SCZY, please send an email to: info@sczyltd.com
