| How to choose a formwork? |

| The mold frame is the support of the mold. For example, the part of the die casting machine that combines and fixes the parts of the mold according to a certain regularity and position, and the part that can be mounted on the die casting machine is called the mold base, and the pushing mechanism, the guiding mechanism and the pre-reset mechanism The die pad and the seat plate are composed. When you use precision formwork, you need to be able to play a very good function, in order to ensure that the entire mold has excellent performance when applied. So when you buy this formwork, you should try to choose The mold frame with very suitable function is more advantageous for everyone's application. The precision mold base retains a small amount of retained austenite relaxation stress as needed, which acts as a buffer. Because the retained austenite is soft and tough, it can partially absorb the martensite rapid expansion energy and alleviate the phase transformation stress. After the cold treatment, it is taken out. The mold frame is heated in hot water to eliminate 40%-60% cold treatment stress. After heating to room temperature, it should be tempered in time. The cold treatment stress is further eliminated, cold crack formation is avoided, stable microstructure performance is obtained, and the mold frame product is stored and used. No distortion occurs. |
