How to Prolong the Service Life of the Die Casting Mould

This article will discuss 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 the user considers the quality of a mould. At the same time, it is a key factor that greatly influences the economic benefit 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. It is worthwhile doing some research about how to prolong the service life of this mould.

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 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, because the mould often has various problems, it can not be used. As for the main factors that result in the breakage of the die casting mould, they can be discussed as follow: during the operation, the pallet mould suppliers  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 mainly caused by the attack, press, compression and expansion. According to 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 lot of methods that can prolong the operation time of the die casting mould. In this article, the author will discuss the methods from three aspects. Firstly, the mould material and the heat treatment of the material have a great effect on the service life of a mould. According to different requirements for the castings and various die casting conditions, people should choose the proper mould steel and optimal heat treatment, because it is a very significant way 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 features of the castings. They can pay attention to the following questions: whether the strength of the mould is enough; whether the pouring head is suitable; whether the cooling device or the warming device is reasonable. Last but not least, in order to prolong the operation time, new manufacturing technology should be explored positively, such as new nitriding method or titanizing method.
