There are always a lot of factors that affect the die-casting mould. From the perspective of the operational performance, the failure of the mould is mainly shown by the following 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 not 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: throughout the operation, the mould is attacked by the aluminium liquid with warm and high pressure.
Besides, since the aluminium liquid has warm, the mould expands when heated and contracts when cooled all of the time. Therefore, the damage of the mould is principally caused by the attack, press, compression and expansion. According to the reasons, the service life of a die-casting mould could be prolonged through reducing the attacking speed, pressure, temperature and so on.
There are a large amount of methods that could prolong the operation time of the die casting mould. In this informative article, the writer will discuss the techniques from three aspects. Firstly, the mould material and the heat treatment of the material have a good impact on the service life of a mould. In accordance with different requirements for the castings and various die casting conditions, people should choose the correct mould steel and optimal heat treatment, because 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 features of the castings. They could focus on these questions: whether the potency of the mould is enough; perhaps the pouring head would work; whether the cooling device or the warming device is reasonable. Last but not least, in order to prolong the operation time, new manufacturing technology must be explored positively, such as for instance new nitriding method or titanizing method.
