There are certainly a large amount of factors that affect the die-casting mould. From the perspective of the operational performance, the failure of the mould is especially shown by the next situations. What comes first is that the mould becomes old and brings about the cracking.
Next, because the mould cracks, it can not be used. Thirdly, as the mould often has various problems, it can’t be used. Are you aware that main factors that end up in 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 high temperature and high pressure Die casting parts.
Besides, because the aluminium liquid has temperature, the mould expands when heated and contracts when cooled most of the time. Therefore, the damage of the mould is especially due to the attack, press, compression and expansion. Based on 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 always a large amount of methods that may prolong the operation time of the die casting mould. In this information, mcdougal will discuss the strategy from three aspects. Firstly, the mould material and the warmth treatment of the material have a great influence on the service life of a mould. According to different requirements for the castings and various die casting conditions, people should choose the appropriate mould steel and optimal heat treatment, as it is just a very significant solution to prolong the operation time.
Secondly, the design of the mould is another important factor. Therefore, when designing the mould, people should fully consider different factors on the foundation of the top features of the castings. They are able to look closely at these questions: whether the potency of the mould is enough; if the pouring head would work; whether the cooling device or the warming device is reasonable. Last although not least, to be able to prolong the operation time, new manufacturing technology should be explored positively, such as for instance new nitriding method or titanizing method.
