Mould materials have been continuously improving in recent years. Many new materials have been discovered and used in different moulds. Although these new materials can be used to increase efficiency and reduce costs, it is not enough to just choose the right material. Some extra treatments such as heat treatment and surface treatment are also needed if the mould is supposed to produce a good quality product.
Heat treatment is used to improve the hardness and strength of the mould. It can also be used to reduce microcracks and keep a consistent size throughout the mould. By controlling the temperature, cooling rate and time of the heat treatment process, the desired result can be achieved. Different materials require different heat treatment techniques.
Surface treatment is another process that can help modify the surface of a mould. Common surface treatments include polishing, electroplating and painting. Polishing is used to make a rough surface smoother and increases its effectiveness in demolding. Electroplating can improve the lifetime of the mould, as it can prevent the mould from being corroded by chemicals. Painting also has its advantages. Swimmers are good for increasing the aesthetics of the mould and improving water resistance.
The types of heat treatment and surface treatment used depends on the characteristics of the mould material. It is therefore important to use the appropriate treatment to ensure maximum performance of the mould. Furthermore, it is beneficial for mould designers to have a good knowledge of the heat treatment and surface treatment techniques.
With the help of the new mould materials and heat and surface treatments, mould designers can easily make higher quality moulds with extended lifetime. Thus, it is important for companies to be aware of these treatments and materials as it can greatly improve the efficiency and accuracy of their production. In addition, advanced materials and treatments also greatly contribute towards reducing costs and energy consumption.
