Due to the excellent performance of aluminum and aluminum alloy, it has been widely used in machinery, electricity, electronics, automobiles, ships, construction, instrumentation, hardware and household products and other fields. Therefore, for important mechanical parts with high mechanical properties and large bearing capacity, they are mainly made by aluminum forging. The weight of aluminum forgings accounts for 77% in aircraft, 68% in tank and 76% in automobile.
Closed die drop forging, or closed die forging, is a forging way that presses heated round metal bar into the shape we need under the pressure of the dies. It will ensure the accuracy of dimensions and little machining allowance, no structure limit, high production efficiency. General steps of closed die drop forging are: mould developing-raw material cutting-heating material-forging-trimming cutting-heat treatment-shot blasting-machining-surface treatment-package. Materials that applied in drop forging process can be stainless steel, alloy steel, carbon steel, copper and other forged materials.
We are focuses on die forging area. At the same time, we are committed to researching the conversion of castings into forgings, which not only reduces customers'costs, but also greatly improves product performance. Our production involve automobile, engineering machinery, railways, mining machinery, military industry, electric power and other fields. We have established cooperative relations with many large domestic and foreign enterprises, such as NEP Machinery Co., Ltd. The U.S GM Group, Caterpillar(U.S.), the United States RAYCO Group Corporation, the United States Bobcat Group and many other large-scale domestic and foreign well-known enterprises. Our forging production have been exported to many developed countries such as the United States, Canada, Europe, and Australia.
Closed die forging is one of the main process for manufacturing steel forgings. Closed Die Forging is a forging process in which dies move towards each other and covers the workpiece in whole or in part. The heated raw material, which is approximately the shape or size of the final forged part, is placed in the bottom die. The shape of the forging is incorporated in the top or bottom die as a negative image. Coming from above, the impact of the top die on the raw material forms it into the required forged form.
