- / Large market development space for machine tool castings in the future
Recently, a seminar on how to improve the quality of machine tool castings was held in Hebei Province. The participants gave a positive response to the future development direction of the casting industry. The representatives of enterprises participating in the meeting reached a consensus that only by improving the quality of castings can they continue to occupy the market. How can we improve the product quality from the manufacturing process? Please see the following report.
First of all, we can't ignore the material factor. Only by choosing a good material from the production material, the quality of machine tool castings will rise. In China, it is mainly made of materials such as resin sand. In many large machine places, the requirements for stiffness are particularly high because it can have certain wear resistance. With a certain degree of stiffness, we can use a good pouring method. Why do we say so? Because our graphite material is relatively soft, with such a solidification process, bubbles can be reduced to a large extent, so that high-quality products can appear.
When pouring machine tool castings, we should pay special attention to relevant matters, because at the initial stage of pouring, when the metal liquid just contacts the foam plastic, it will decompose a lot of gas, which will cause splashing of the metal liquid. We generally adopt the method of fine pouring, and only slow work can produce fine work. Only when the gating system is almost full can we pour quickly. The quality obtained in this way is better and more efficient.
From this, it can be seen that the manufacturing process of machine tool castings is a comprehensive process that needs attention in all links. Only by solving the problems such as pouring, can we produce high-quality machine tool castings and give more development advantages to the casting Market in the future.
