The difference between hot forming and cold forming of Zhuji springs
2023-04-26
Zhuji springs utilize various carbon steel elements and alloy materials. After being manufactured and bent using CNC machine tools, they form into various differently shaped spring products. According to their forming method, they can be divided into two major categories: spring hot forming technology and cold forming technology.
1: Spring Cold Forming
The cold forming process needs to be completed automatically in one go. The eccentric cold forming process has certain limitations in use. So-called cold forming means that when the spring is made, it is usually at room temperature. Even if heating is used, the temperature is very limited, controlled within 60 degrees.
Cold-formed springs are mainly distinguished by their material. It's not to say that cold-formed springs are necessarily inferior in mechanical properties. However, if the spring material is carbon steel, the effect of cold forming will be relatively poor.
2: Spring Hot Forming
Theoretically, springs produced by hot forming should have better performance. However, in practice, there are no particular advantages, mainly due to limitations in production equipment technology. Due to the limited availability of CNC 2-axis hot forming equipment, there are issues with precision and poor forming effects in terms of shape control.
In the spring sales market, the current proportion of hot-formed springs is far less than half. The quality of precision and surface decarburization to a certain extent restricts the sales of these springs. This is an urgent problem that Zhuji Spring needs to solve in its production and research and development.
