Die Casting Supplier Introduces The Characteristics Of Die Casting
Die casting is abbreviated as die casting. It is a casting method in which molten alloy liquid is poured into a press chamber, the cavity of a steel mold is filled at high speed, and the alloy liquid is solidified under pressure to form a casting. Die Casting Supplier introduces the characteristics of die casting:
①The molten metal fills the cavity under pressure, and crystallizes and solidifies under higher pressure, the common pressure is 15-100MPa.
②The molten metal fills the cavity at a high speed, usually 10-50 meters per second, and some can exceed 80 meters per second, (the linear velocity of the cavity through the inner gate-the inner gate speed), so the molten metal The filling time is extremely short, and the cavity can be filled in about 0.01-0.2 seconds (depending on the size of the casting).
Die casting is a precision casting method. Die castings made by die-casting have very small dimensional tolerances and high surface accuracy. In most cases, die castings can be assembled and used without turning. Parts can also be cast directly. From small parts such as general camera parts, typewriter parts, electronic computing devices, and decorations, as well as complex parts of vehicles such as automobiles, locomotives, and airplanes, most of them are manufactured by die casting.
