  • Zinc alloy is an alloy composed of other elements based on zinc. The alloying elements that are often added are aluminum, copper, magnesium, cadmium, lead, and titanium. Zinc alloy has low melting point, good fluidity, easy fusion welding, brazing and plastic processing, corrosion resistance in the atmosphere, easy recycling and remelting of residual waste, but low creep strength, prone to dimensional changes caused by natural aging. Prepared by melting, die casting or pressure processing.

  • A shaft is basically the rotating part of any machine with a circular cross-section that is used to transmit power from one part to another or from a power generator to a power absorber. In order to transmit power, one end of the shaft is connected to the power source, and the other end is connected to the machine. Shafts can be solid or hollow as required, with hollow shafts helping to reduce weight and providing advantages.

  • Die forging is a method of forming on a forging die developed on the basis of free forging and die forging in order to solve the problems of low productivity and poor precision of free forging, and to achieve the needs of large-scale and specialized production of forgings. Die forging is the abbreviation of model forging. The forging die (forging die) is generally composed of an upper die and a lower die. The upper and lower dies of the forging die are respectively fixed on the hammer head and the die pad. or die groove), the shape and size of the cavity of the groove is the same as the shape and size of the forging. During die forging, the blank is placed on the lower die, and the upper die moves down with the hammer (or slider) to close the die (one or more times) to hit the blank. Under the action, plastic deformation is generated and the groove is filled, and finally a forging with the same shape as the groove is obtained.

  • Under normal circumstances, the color of the finished precision castings is silver-white or silver-gray, but after a period of use, some castings will appear black, and the whole or part of the castings are processed products and designs. If the concept does not match, it will be deformed. What are the reasons and solutions for blackening and deformation?

  • Aircraft landing gear, as an important safety functional component of an aircraft, is an important support system for aircraft take-off, landing, ground taxiing and parking, and is the main load-bearing component of an aircraft. It absorbs and dissipates the impact energy formed by the aircraft and the ground during the landing and taxiing process, ensuring the safety of the aircraft during the ground movement. The technical level and reliability of the landing gear have an important impact on the overall performance and safety of the aircraft.
