How to Prolong the Service Life of the Die Casting Mould

This informative 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 the consumer considers the caliber of a mould. At once, 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. It’s worthwhile doing some research about how to prolong the service life of the Aluminium die casting.

There are certainly a large amount of factors that affect the die-casting mould. From the perspective of the operational performance, the failure of the mould is principally shown by the following situations. What comes first is that the mould becomes old and brings in regards to the cracking.

Next, because the mould cracks, it can not be used. Thirdly, since the mould often has various problems, it can’t be used. As for the main factors that end up in 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 warm and high pressure.

Besides, because the aluminium liquid has warm, the mould expands when heated and contracts when cooled most of the time. Therefore, the damage of the mould is principally caused by the attack, press, compression and expansion. Based on the reasons, the service life of a die-casting mould may 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, mcdougal will discuss the methods 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 appropriate mould steel and optimal heat treatment, as it is really 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 cornerstone of the top features of the castings. They can pay attention to the following questions: whether the strength of the mould will do; whether the pouring head is suitable; perhaps the cooling device or the warming device is reasonable. Last although not least, to be able to prolong the operation time, new manufacturing technology should be explored positively, such as for instance new nitriding method or titanizing method.
