The main features of die casting that distinguish it from other casting methods are high pressure and high speed.
1 The molten metal fills the cavity under pressure and crystallizes and solidifies at a higher pressure. The common pressure is 15-100 MPa.
2 The metal liquid fills the cavity at high speed, usually at 10-50 m/s, and some can also exceed 80 m/s (the line speed of the cavity introduced into the cavity through the ingate), so the molten metal The filling time is extremely short, and the cavity can be filled within about 0.01-0.2 seconds (depending on the size of the casting).
