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 an individual considers the quality of a mould. At the same time frame, it is really 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 just how to prolong the service life of the mould.
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 mainly shown by the following situations High pressure die casting. What comes first is that the mould becomes old and brings concerning the cracking.
Next, because the mould cracks, it can not be used. Thirdly, as the mould often has various problems, it can’t be used. When it comes to main factors that bring about the breakage of the die casting mould, they may be discussed as follow: during the operation, the mould is attacked by the aluminium liquid with high temperature and high pressure.
Besides, since 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 mainly 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 article, the writer will discuss the techniques from three aspects. Firstly, the mould material and the warmth treatment of the material have a great influence on the service life of a mould. According to different requirements for the castings and various die casting conditions, people should choose the correct mould steel and optimal heat treatment, because it is really a very significant way to prolong the operation time.
