Precision die casting method for alloy die casting

Metal die casting process is a high-precision high-pressure metal casting process is a precision casting method. In 1964, the Japan Die Casting Association defined die casting as a method of producing high precision cast surfaces in a relatively short time with high precision. The United States said die casting for die casting British is said to be die casting die casting pressure.

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

Metal die casting machining is a casting method used for precision casting, dimensional tolerances made from the casting of a very small surface precision is very high, in most cases the casting is not re-turned assembly applications, threaded parts can be cast directly out. From the general camera parts, typing parts, electronic calculators and accessories and other small parts, as well as cars, motorcycles, aircraft and other complex parts of transportation tools are mostly manufactured by 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 frame. 2 Die casting is a casting method that integrates the liquid gold into the cavity, and the high-speed mold filling makes the alloy liquid solidify under pressure. Die casting is distinguished from other casting methods of high pressure and high speed.

The liquid metal is filled with cavity under pressure and crystallized under high pressure. The common pressure is 15 ~ 100mpa.

At high speed, the liquid metal filling cavity is usually 10-50 m/s and some can exceed 80 m/s, so the filling time of the liquid metal is very short, about 0.01 to 0.2 seconds. Die-casting alloy and die-casting die are the three main factors in die casting production. The three elements of the casting process are organically combined to make a stable rhythm and efficient production of appearance and intrinsic quality, good dimensions in line with the requirements of qualified casting drawings or agreements for higher quality castings.
