Die Casting Terms and Definitions

This short 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 a critical indicator when the user considers the caliber of a mould. At the same time frame, it is a key factor that greatly influences the economic advantageous asset 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 High pressure die casting. It is worthwhile doing some research about how to prolong the service life of the 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 especially 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, 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 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 high temperature, the mould expands when heated and contracts when cooled most of the time. Therefore, the damage of the mould is especially brought on by the attack, press, compression and expansion. In line with 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 lot of methods that will prolong the operation time of the die casting mould. In this article, the author will discuss the techniques from three aspects. Firstly, the mould material and the heat treatment of the material have a good impact on the service life of a mould. Based on 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 solution 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 could look closely at the next questions: whether the strength of the mould will do; whether the pouring head would work; whether the cooling device or the warming device is reasonable. Last however, not least, to be able to prolong the operation time, new manufacturing technology must be explored positively, such as for instance new nitriding method or titanizing method.
