Botou Junteng Casting Co.,Ltd

The automotive industry continues to develop based on the needs of energy, safety, comfort and other factors. The automotive industry's development needs for materials are in the era of application of aluminum-magnesium alloys to replace steel, cast iron and other energy-consuming high-quality materials. Traditional body parts are mainly made of steel sheet stamping or hydraulic bulging or sheet welding. If aluminum alloy is used, high strength and high toughness are required. The application of aluminum alloy has the advantage of highly integrated parts. The performance requirements for different parts are different. Some need to improve their elongation and some need to improve the corrosion resistance. With the development of high vacuum die casting technology, processing of  die-casting aluminum parts  requires more excellent aluminum alloys with various properties. In order to realize the demand for high-plasticity aluminum alloys, scholars from Germany and Japan have ...

In recent years, with the rapid development of the automotive, aerospace and computer industries, higher requirements have been placed on light weight, high toughness and corrosion resistant castings. For aluminum alloy parts, the processing and forming of high-strength, high-toughness, corrosion-resistant alloys, deformed alloys, and the forming process of large and complex alloy parts have become research hotspots for lightweight alloys. However, the mechanical properties of most cast aluminum alloys are currently low tensile strength and low elongation. With the development of technology, the demand for high-strength, lightweight castings such as  die-casting aluminum lamp base , has gradually increased, and the advantages of using aluminum die-casting to prepare aluminum alloy parts have attracted attention. The die casting process (pressure casting) is a special casting process commonly used in the processing industry. The fluid metal or semi-fluid metal is filled into the ...

As a special forming technology, pressure casting has been widely used in many industries and fields, especially for the mass production of automobiles, motorcycles, internal combustion engines, electronics, instrumentation and aerospace industries. Quality defects of aluminum alloy die-casting parts 1, stomata It refers to the holes and holes of different sizes appearing inside or on the surface of the  die-casting aluminum parts . It has a smooth surface and is mostly round in shape. The generation of pores can lead to insufficient hardness of the die casting and affect the appearance of the surface. There are many bolt holes, oil holes and various mounting holes on the die-cast aluminum alloy box, which directly affects the assembly quality and performance of the engine, and the quality of the die casting process needs to be strictly controlled. 2, mixed When aluminum alloy is smelted, it is often found that a solid compound composed of heavy elements is deposited o...

Three points of attention for cast aluminum parts produced by  die-casting aluminum parts factory : 1. The overall die casting is a metal die casting process that heats the workpiece as a whole and then cools it at an appropriate speed to modify its overall mechanical function. The overall die casting of steel has four basic processes of annealing, normalizing, quenching and tempering. Annealing is to heat the workpiece to the proper temperature. According to the material and the workpiece standard, different insulation time is selected, and then slowly cooled. The purpose is to make the internal structure of the metal reach or close to the equilibrium condition, so that the internal stress of the previous process can be released. Excellent process function and application function, ready for further quenching. Normalizing or normalizing is to cool the workpiece to a suitable temperature and then cool it in air. The effect of normalizing is similar to annealing, but the resultin...
