High Quality CNC Machining Machined Casting Parts

High Quality CNC Machining Machined Casting Parts

Under normal circumstances, when die-casting thin-walled castings, the flow resistance in the cavity is large, and the ingate is also thinner in thickness, so it has a large resistance, so it is necessary to have a larger filling specific pressure to ensure that it is needed. Insulation speed. For thick-walled castings, on the one hand, the selected ingate speed is lower, and the solidification time of the metal is longer, and a smaller filling specific pressure can be used; on the other hand, in order to make the casting have a certain Density, also need to have sufficient pressurization specific pressure to meet the requirements. For complex shapes of castings, the filling specific pressure should be higher. In addition, such as the type of alloy, the size of the gate, the mold clamping ability of the die casting machine The power and the strength of the mold should be properly considered. The size of the filling specific pressure is mainly calculated according to the selected ingate speed. As for the pressure ratio of the supercharging pressure, according to the alloy type, the following table values can be selected. When the exhaust condition in the cavity is good and the ratio of the thickness of the gate to the wall thickness of the casting is appropriate, a low pressure ratio can be selected. The worse the exhaust condition, the greater the ratio of the thickness of the gate to the wall thickness of the casting. In hours, the higher the pressure ratio, the higher the pressure.
