This information will discuss just how to prolong the service life of the die-casting mould from three aspects namely material, design and manufacture. The service life of a die casting mould is a very important indicator when an individual considers the quality of a mould. At the same time, it is just a key factor that greatly influences the economic advantage of the die casting industry. Therefore, to improve the service life of a mould is of great help for the economic benefits and social benefits Aluminium die casting. It is worthwhile doing some research about just how to prolong the service life of this mould.

There are 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 these situations. What comes first is that the mould becomes old and brings concerning the cracking.

Next, because the mould cracks, it can’t be used. Thirdly, since the mould often has various problems, it can’t be used. When it comes to main factors that lead to the breakage of the die casting mould, they can be discussed as follow: throughout the operation, the mould is attacked by the aluminium liquid with high temperature and high pressure.

Besides, because the aluminium liquid has high temperature, the mould expands when heated and contracts when cooled all the time. Therefore, the damage of the mould is especially due to 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 can prolong the operation time of the die casting mould. In this short article, the author will discuss the methods from three aspects. Firstly, the mould material and 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 proper mould steel and optimal heat treatment, since it is just a very significant method 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 basis of the options that come with the castings. They are able to look closely at the next questions: whether the strength of the mould is sufficient; whether the pouring head would work; whether the cooling device or the warming device is reasonable. Last however, not least, in order to prolong the operation time, new manufacturing technology should be explored positively, such as for example new nitriding method or titanizing method.
