The mold drives the injection head through the hydraulic cylinder to press the molten metal into the cavity at high speed. Because of the high pressure, it is commonly called casting process.
Die-casting die: it is a method of casting liquid die forging, which is a process completed on a special die-casting die forging machine. Its basic technological process is: firstly, molten metal is cast at low speed or high speed and filled into the cavity of the mold, and the mold has a movable cavity surface. It is forged under pressure with the cooling process of molten metal, which not only eliminates the shrinkage and porosity defects of the blank, but also makes the internal structure of the blank reach the forged broken grains. The comprehensive mechanical properties of the blank have been significantly improved.
Die-casting dies are the three elements of die-casting production, and they are indispensable. The so-called die casting process is the organic comprehensive application of these three elements, so as to produce qualified castings with good appearance and internal quality, and the size meets the requirements of drawings or agreements, even high-quality castings stably, rhythmically and efficiently.
The range here is circular, and the unsigned type of-1 is not 1, but 2 32-1. The reason for this is the following£º
