What are the spring elements commonly used in molds

Performance introduction of spring elements commonly used in molds:

There are three types of spring elements commonly used in molds, mechanical equipment, tooling and fixtures, and their use characteristics and performance are as follows:

a.Metal coil springs: The common metal springs (rectangular springs) currently on the market generally have two standards: Japanese JIS and ISO-10243. This type of spring is suitable for higher-speed molds, mechanical equipment, fixtures, etc., and its characteristics are mainly reflected in Good stability, not easy to deform, easy to install, high temperature resistance and low cost of use. It is more commonly used and made of alloy spring steel materials.

B. Polyurethane spring: also called Youlijia, with a Shore hardness between 70 and 95, low cost, relatively poor stability, and easy to deform. It is mostly used for deep drawing, buffering, rebounding, etc.

c. Nitrogen gas spring: It is an elastic element that uses high-pressure nitrogen as the working principle. There are many domestic and foreign brands. After recent years of investment and development, the quality of domestic brands is comparable to foreign products. Its characteristics are good stability and extended molds Service life, often used in large household appliances, automobile molds, etc., can be competent for difficult tasks such as coil springs, polyurethane springs, etc., but the use cost is high and it is not suitable for high-speed use.
