Heavy melting steel is a designation for recyclable steel. It is categorised into two major categories: HMS 1 and HMS 2. The difference between the two is HMS 1 does not contain galvanized and cast iron, whereas HMS 2 does. Because both grades guarantee a minimum piece thickness â?? at least 1/4inch (6.3mm) for HMS 1, and 1/8 in for HMS 2 â?? consignments have a high density. The typical constituents are plates, truck parts, structural items, large machinery parts, automatic parts, pipes, post consumer steel goods. Chemical Composition: C:0.06 â?? 0.082% Mn:0.75 â?? 1.05% SI:0.13 â?? 0.28% P: Max 0.035% S: Max 0.045% Ar: Max 0.15%
We have years experience of aluminum alloy casting, since we need to produce the corrugated pipe molding blocks for our PE/PVC corrugated pipe extrusion line which is our another main business started from 1980's. and now we produce aluminum casting pieces according to customer's requests and drawings with the same superior quality as our mold blocks for our extrusion line. The weight of casting pieces can range from 0.25kg to 1200kg. 1 Metal liquid is shaped solidly by the effect of pressure, which can raise the fluid of the metal liquid and ensure a better shape of the casting piece. This casting method is benefit to shape casting pieces with require of clear silhouette and glabrous surface, especially suitable for the casting of large pieces of thin wall. 2 The casting pieces is formed in pressure, so the shrink spot on the pieces can be filled adequately by the metal liquid. As a result, the casting pieces are made with dense texture and high mechanical performance. 3 The technical parameter of the low pressure casting can be adjusted freely within the technical range,which can ensure an even and smooth metal shape and avoid the defect of the casting piece for the purpose of improving the quality of the casting pieces.
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.
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.
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.
Carbon steel casting Category:Steel casting Carbon steel casting has high strength, plasticity and toughness. Common grades include Q195, Q215, Q235, Q255, Q275, etc. Product Description Carbon steel casting is used in heavy machinery to manufacture parts that are subject to heavy loads, such as rolling mill stands, hydraulic press bases, etc. It is also used to manufacture more important mechanical parts with complex shapes and high requirements on mechanical properties, and it is difficult to form by forging and other methods in the process. Carbon steel refers to iron-carbon alloys, generally the carbon content is between 0.0218% and 2.11%. As the carbon content is higher, the strength of carbon steel is higher, but correspondingly, the plasticity of the product will decrease. Usually there are elements such as silicon manganese in carbon steel. These different types of small amounts of elements will have different effects on the strength and hardness of carbon steel products. Cast carbon steel generally has a relatively low production cost, gradually has high strength and toughness, and has good plasticity, and can be used to manufacture parts that bear large loads, such as rolling mill stands for heavy mechanical clocks, hydraulic press bases, etc. It can also be used to manufacture parts that are subjected to high forces and shocks, such as wheels, couplers, bolsters and side frames on railway vehicles.
