Characteristics of Die Casting
Pressure casting, referred to as die casting, is a method of casting in which a molten alloy is poured into a press chamber, which fills the cavity of a steel mould at high speed and causes the alloy to solidify under pressure to form a cast.
The die casting method is a method of casting in which a molten alloy is poured into a press chamber, filling the cavity of a steel mould at high speed and allowing the alloy to solidify under pressure to form a cast part. The main features of die casting that distinguish it from other casting methods are high pressure and high speed.
(1 ) The metal liquid is filled in the cavity under pressure and crystallised and solidified under higher pressure, commonly 15 - -100MPa.
(2) The metal liquid fills the cavity at high speed, usually at 10 - -50 m sec, some can also exceed 80 m sec, (through the inner gate into the cavity of the line speed a inner gate
speed), so the metal liquid filling time is very short, about 0.01- 0 2 seconds (depending on the size of the casting and different) within the cavity can be filled. Die-casting machines, die-casting alloys
and die-casting moulds are the three main elements of die-casting production, the lack of - can not. The so-called die-casting process is the organic use of these three elements, so that can be stable and rhythmic
Rhythmically and efficiently produce the appearance, the internal quality of good, size in line with the drawings or agreement requirements of qualified castings, and even quality castings.
