Precision Die Casting Method for Alloy Die Casting

Metal die-casting process is a high-precision high-pressure metal casting process and a precision casting method. In 1964, the Japan Die Casting Association defined die casting as a method of producing high-precision cast surfaces with high precision in a relatively short period of time. The United States says that die-casting is called die-casting. The United Kingdom is said to be the pressure of die-casting, while the familiar domestic industry is called die-casting in Japan. The castings produced during the die-casting process are called die castings.

Hardware die-casting is a casting method used for precision casting, with very small dimensional tolerances made from castings and high surface accuracy. In most cases, castings are not re turned and assembled, and threaded parts can be directly cast. Small parts such as cameras, typewriters, electronic calculators, and accessories, as well as transportation vehicles for complex parts such as cars, motorcycles, and airplanes, are mostly manufactured using die casting.

The tensile strength of these materials is almost twice that of ordinary cast alloys. It has a more positive impact on the production of aluminum alloy wheel hub frames, etc. Die casting is a casting method that integrates molten metal into the cavity and solidifies the alloy under pressure through high-speed mold filling. Die casting is different from other casting methods in terms of high pressure and high speed.

The common pressure for metal liquid to fill the mold cavity under pressure and crystallize and solidify under high pressure is 15-100mpa.

The liquid metal used to fill the mold cavity at high speed can usually exceed 80 meters per second at a speed of 10-50 meters per second, so the filling time of the metal liquid is very short, about 0.01 to 0.2 seconds. Die casting alloys and die casting molds are the three main factors in die casting production. The organic combination of the three elements in the casting process ensures a stable rhythm and efficient production of appearance and internal quality. Good dimensions meet the requirements of qualified casting drawings or agreements, resulting in higher quality castings.
