Die Casting and Casting Types

This information 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 an individual considers the grade of a mould. At once, it is a key factor that greatly influences the economic good thing about 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 how exactly to prolong the service life of the mould.

There are always a large amount of factors that affect the Aluminium die casting mould. From the perspective of the operational performance, the failure of the mould is especially shown by the next situations. What comes first is that the mould becomes old and brings about the cracking.

Next, as the mould cracks, it can’t be used. Thirdly, because the mould often has various problems, it can not be used. Are you aware that main factors that end in the breakage of the die casting mould, they may be discussed as follow: through the operation, the mould is attacked by the aluminium liquid with warm and high pressure.

Besides, because the aluminium liquid has high temperature, 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. According to 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 always a lot of methods that could prolong the operation time of the die casting mould. In this short 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. Based on different requirements for the castings and various die casting conditions, people should choose the correct mould steel and optimal heat treatment, since it is really a very significant method 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 top features of the castings. They are able to pay attention to the next questions: whether the potency of the mould is enough; if the pouring head works; whether the cooling device or the warming device is reasonable. Last although not least, in order to prolong the operation time, new manufacturing technology ought to be explored positively, such as for instance new nitriding method or titanizing method.
