When you pick up a metal part, have you ever wondered how it is made? Is it cast by pouring molten metal into a mold, or is it forged by high temperature and huge pressure? Sand casting and forging are the two most common metal processing methods.

In the previous article, we introduced sand casting, precision casting and metal mold casting. I believe everyone has a preliminary understanding of the characteristics of different casting processes.

If there is a "all-match model" in the casting industry, it must be sand casting. It is one of the most widely used casting methods. It uses special sand to make sand casting molds, pours molten metal into it, and gets sand castings​ after cooling.

The machinery manufacturing industry is undergoing profound changes, with the main development trends focusing on automation, digitalization and sustainability. The widespread application of automation technology has significantly improved production efficiency and product quality, especially the popularity of industrial robots and automated production lines, making the production process more precise and efficient.

The machinery manufacturing industry covers a wide range of fields, including agriculture, industry, automobiles, engineering, etc. Its development trend is very important to the entire industry. The following are recent trends in the machinery manufacturing industry, which I hope will be of reference to you.
