There are a lot 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 following situations. What comes first is that the mould becomes old and brings concerning the cracking.
Next, as the mould cracks, it can’t be used. Thirdly, since the mould often has various problems, it can not be used. Are you aware that main factors that result 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 high temperature and high pressure.
Besides, as the aluminium liquid has temperature, the mould expands when heated and contracts when cooled all the time. Therefore, the damage of the mould is especially caused by the attack, press, compression and expansion. Based on 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 lot of methods that could prolong the operation time of the die casting mould. In this information, the writer will discuss the strategy from three aspects. Firstly, the mould material and the heat treatment of the material have a great 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 proper mould steel and optimal heat treatment, as it is really a very significant way to prolong the operation time.
Secondly, the look 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 can focus on the following questions: whether the potency of the mould is enough; perhaps the pouring head works; perhaps the cooling device or the warming device is reasonable. Last however, not least, to be able to prolong the operation time, new manufacturing technology must certanly be explored positively, such as for instance new nitriding method or titanizing method.
