Die casting process introduction During the injection process, the injection speed is directly affected by the pressure, and together with the pressure, it plays an important role in the internal quality, surface quality and contour clarity of the casting. In production, the speed is usually expressed in two types: the punch speed (injection speed) and…

CNC programming considerations All aspects worthy of our attention and attention in the process of CNC programming. 1. The speed of the white steel knife should not be too fast. 2. For copper work, use less white steel knives, and more use flying knives or alloy knives. 3. When the workpiece is too high, you…

Die casting mold pouring system Die casting is one of the important methods for non-ferrous metal forming. During the die-casting process, due to the different flow conditions of the molten metal in the cavity, undesirable phenomena such as cold barriers, patterns, pores, and segregation may occur. In order to prevent these undesirable phenomena, it is…
