Today we continue to study the valve. In daily use, how should we clean and maintain the valve to make it last longer?

In the last article, we discussed the application scope, types, and development of valves. Today, let's study the requirements for valve installation and acceptance.

The user industry of the valve is very wide. In addition to the household, it can also be divided into petroleum, petrochemical, chemical, metallurgy, electric power, water conservancy, urban construction, machinery, coal, food and others.

In the last article, we introduced the development history and technological process of precision casting. Today, we will talk about the classification of precision casting.

Precision casting is a commonly used process in metal processing. Today we will introduce the development history of precision casting and its technological process.

Foundry parts have wide adaptability and good comprehensive mechanical properties. So do you know what types of foundry parts are and the technical requirements?

As the temperature increases, the air permeability of the cast part shell continues to decrease. Today we are going to talk about the air permeability of casting parts.

The quality of foundry technology is related to the production of foundry parts. Therefore, in order to ensure the quality of foundries, it must have a reasonable structure.

Foundry parts and forging parts are both manufacturing processes used to process metal materials. The difference is that forged parts are hammered and pressed to make the metal material in a plastic state into a workpiece with a certain shape and size.
