This article 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 an essential indicator when an individual considers the caliber of a mould. At the same time frame, it is a key factor that greatly influences the economic advantage of the die casting industry. Therefore, to boost the service life of a mould is of great help for the economic benefits and social benefits. It’s 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 the following situations. What comes first is that the mould becomes old and brings about the cracking Die casting parts.

Next, because the mould cracks, it can’t be used. Thirdly, as the mould often has various problems, it can not be used. When it comes to main factors that end 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 warm and high pressure.

Besides, as 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 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 a large amount of methods that will 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 warmth treatment of the material have a good effect 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 way 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 top features of the castings. They can pay attention to these questions: whether the strength of the mould is sufficient; if the pouring head works; perhaps the cooling device or the warming device is reasonable. Last but not least, in order to prolong the operation time, new manufacturing technology should really be explored positively, such as new nitriding method or titanizing method.
