Metal material forming is widely used in many industries. Its specific applications include but are not limited to the following aspects:
1. Mechanical manufacturing
Important parts production: important parts that bear impact or alternating stress (such as machine tool spindles, gears, crankshafts, connecting rods, etc.) and thin-walled parts are all forged products (i.e. forgings). For example, the mass fraction of plastic formed parts on aircraft is about 85%, and the mass fraction of forgings on cars and tractors is 60%-80%.
Complex structure manufacturing: Through superplastic forming technology, parts that are difficult to process by ordinary methods can be processed, such as superplastic sheet gas expansion forming, isothermal forging, superplastic extrusion and differential temperature stretching. Widely used in aerospace, construction, transportation, electronics and other fields.
2. Defense Industry
Manufacturing of complex parts: Squeeze casting forming technology produces many parts in the weapons industry, such as light tank road wheels, projectile hoods, mortar lower bodies, missile secondary rudders, etc. The original process of the missile secondary rudder was forging the blank and then machining, which was complex and costly. The use of extrusion casting simplifies the process flow and greatly saves costs.
3. Automobile and motorcycle industry
Manufacturing of piston blanks: First Automobile Manufacturing Plant and Dongfeng Automobile Manufacturing Plant have used extrusion casting to produce pistons for many years, and can produce various types of pistons with diameters of 90mm – 190mm.
Brake cylinder production: After the automobile brake cylinder adopts the extrusion casting process, the product quality is improved, and the cost is reduced.
Application of shock absorber sleeve: The motorcycle shock absorber sleeve also adopts the extrusion casting process, which has achieved good economic and social benefits.
4. Electronic and electrical industry
Housing and bracket manufacturing: In the manufacturing process of electronic and electrical products, metal forming technology is widely used to manufacture housings, brackets, connectors, and other components.
Connection and reliability improvement: Stable and reliable connections can be achieved through metal welding and joining technology, improving product reliability and service life.
5. Building and transportation
Building structure: Metal materials are often used to make frame structures, support structures, connectors, etc., with high strength and rigidity, and can withstand large loads.
Transportation: Metal materials are used to make car bodies, engines, etc., with high strength and durability, which can ensure the safety and stability of transportation.
6. Other fields
Powder metallurgy and 3D printing: high-throughput preparation technology for metal materials, such as the DLM-120HT high-throughput additive preparation equipment for metal materials developed based on laser selective melting technology, which can realize the rapid preparation and screening of a variety of metal materials, and is suitable for the composition screening, performance research and gradient material research of new metal materials such as steel materials, aluminum alloys, titanium alloys, nickel-based high-temperature alloys, and high-entropy alloys.
Superplastic forming technology: The application scope of superplastic forming technology (SPF) has been expanded to zinc-aluminum alloys, aluminum alloys, titanium alloys, copper alloys, magnesium alloys, nickel-based alloys, and ferrous metal materials, and has now been extended to ceramic materials, composite materials, intermetallic compounds, etc. This technology has the advantages of low forming pressure, high mold life, and one-time precision forming. It has been more and more widely used in aerospace, construction, transportation, electronics, etc.
