The development method of tungsten crucible
Due to the increasing demand for tungsten crucible in the year, now many manufacturers began to join the production, but the quality of production has some problems. After many years of research, Zhengzhou Sanhui has successfully produced high quality tungsten crucible, today, let’s understand the development process of tungsten crucible.
In the past, the overall production of tungsten crucible used mechanical pressing method, which can not meet the requirements, the main reason is that the aspect ratio is too big, and the suppression density is uneven, and if the core design is improper, which will lead to the cracking at the bottom of the crucible and the wall of tungsten crucible.
In view of this situation, Zhengzhou Sanhui uses arc over in this area, which can effectively prevent the stress concentration in this area of tungsten crucible in the pressing process, at the same time, in order to facilitate the release, a certain of angle is designed at the bottom to the top of the mold.
After the above research and development, the performance of tungsten crucible is good, the production cost is greatly reduced, to meet the high demand of the market.
