There are always a large amount of factors that affect the die-casting mould. From the perspective of the operational performance, the failure of the mould is principally shown by these situations. What comes first is that the mould becomes old and brings concerning the cracking.
Next, as the mould cracks, it can not be used. Thirdly, because the mould often has various problems, it can not be used. When it comes to main factors that bring about the breakage of the die casting mould, they could be discussed as follow: during the operation, the mould is attacked by the aluminium liquid with temperature and high pressure.
Besides, as the aluminium liquid has high temperature, the mould expands when heated and contracts when cooled all of the time. Therefore, the damage of the mould is especially brought on by the attack, press, compression and expansion. According to the reasons, the service life of a die-casting mould can be prolonged through reducing the attacking speed, pressure, temperature and so on.
There are a large amount of methods that can prolong the operation time of the die casting mould. In this article, mcdougal will discuss the strategy from three aspects. Firstly, the mould material and the heat treatment of the material have a good influence on the service life of a mould. Based on different requirements for the castings and various die casting conditions, people should choose the appropriate mould steel and optimal heat treatment, since it is just a very significant method to prolong the operation time.
Secondly, the style of the mould is another important factor. Therefore, when designing the mould, people should fully consider different factors on the cornerstone of the options that come with the castings. They could focus on the following questions: whether the effectiveness of the mould is enough; perhaps the pouring head would work; if the cooling device or the warming device is reasonable. Last but not least, to be able to prolong the operation time, new manufacturing technology ought to be explored positively, such as for example new nitriding method or titanizing method.
