Aluminum alloy precision die casting part

[]

Under the normal die-casting conditions, the jet and jet flow die-casting machine presses the metal into the ordinary die-casting model cavity. At the initial stage, the metal liquid passing through the inner gate is directly shot forward at a high speed like a bullet under the action of motion energy, and its direction depends on the direction of the inner gate, The metal flow in this state is called "the metal liquid sprayed at high speed will collide with the cavity wall and core or other metal flow. At this time, part of the movement energy in the metal liquid will be converted into heat energy and pressure, and will flow along the cavity wall while changing the metal flow and the direction of advance. Because the remaining movement can make the metal liquid move along a straight line is still strong, so the metal flow at this stage is similar to the general pressure flow (from the side with high pressure to the side with low pressure) is different, which is called "jet flow". Jet and jet flow have a very obvious characteristic, that is, they can move straight under the action of a large amount of motion energy. This feature can be used to fill the parts with high resistance and without exhaust gas, which are difficult to fill by pressure flow.
