China die casting factory still has many shortcomings at present, but it has been making continuous progress. Today we come to understand die casting.

Pressure is the basic feature of the die-casting process. The filling flow and compaction of molten metal are all completed under the action of pressure. Pressure is divided into dynamic injection force and pressurized injection force. The function of a dynamic injection force is to overcome various resistances and ensure that the molten metal reaches a certain speed during filling. The function of the pressurized injection force is to compact the die casting after the filling is completed, improve the density of the die casting, and make the contour of the die casting clear. The injection force exerts pressure on the molten metal through the injection punch.

The injection speed is also called the punch speed, which is the speed at which the injection punch in the pressure chamber pushes the molten metal, that is, the speed of the injection punch. The injection speed changes during the injection process. It can be divided into two stages, low speed, and high speed. The speed control valve of the die casting machine can be used for stepless speed regulation.

Like aluminum die casting , there are many points that need to be paid attention to, so experience and carefulness are still needed.
