What is a mould? It is a pattern or tool of the product by the means of injection, blowing, ejection, casting, punching and so on in the industrial production. In order to meet the need of the products, there are nine main development trends for the mould.
What comes first is that the mould will gradually tend to the upsizing development. This is the development of the industry. At present the molding spare parts are becoming larger and larger. T the same time it is the requirement for the high production efficiency.
The second development trend is that the accuracy of the mould is higher and higher. Ten years ago, the accuracy of the precision mould was about five micrometers. But now the accuracy can achieve two or three micrometers. Some professional manufacturers are making effort to produce the mould whose accuracy will be one micrometer.
Thirdly, the multi-functional compound mould will be further developed. The new-type mould can not only punch the forming components but also can take on other tasks such as overlying, threading, riveting and locking. In a word, the requirement for the steel material is higher and higher.
The fourth development trend is that the plastic mould plays a more and more important role in the hot runner mould. Because the hot runner technology can improve the production efficiency and quality and meanwhile save the raw material to some degree, this technology is developed very quickly. The hot runner technology has been adopted by many factories to produce the plastic mould.
Fifthly, with the development of the plastic forming technology, the air aided mould and high-pressure injection mould are the development trend of the mould. This kind of mould is characterized by the following features, such as good rigidity, resistance to high pressure and excellent tightness.
Sixthly, the application of the standard component will be wider and wider. The standardization of the mould and the wide application of the standard component will have a great effect on the manufacturing cycle of the mould. At the same time it is of great help to improve the quality and reduce the cost.
Seventhly, the rapid and economic mould will have a promising future. It is the manufacturing era for diversities and short-run. From this point, people can see that the usage cycle of the product will be shortened and meanwhile the diversities will often be changed. In a word, this so-called rapid and economic mould gains more and more concerns.
The eight development trend is that with the light-weight development of the vehicles and electric motors the die-casting mould will be more and more important. At the same time, because of the complexity and accuracy of the spare parts the requirement for the die-casting mould is higher and higher.
Last but not least, the middle and high end mould will be one of the development trends. This is the result of the market’s changeability.
