DAI Spring Features
#
DAI Spring is especially designed for the stamping mold / plastic mold ; DAI spring can have a powerful motivation in a small space to compare with the round wire coil spring . DAI spring has the type of lightest load spring , light load spring, medium load spring , heavy load spring , super heavy load spring , hyper heavy load spring , and the hight deflection spring . DAI springs are easy for choosing because they are coating by their own different color.

# The SWOSC-V material has the performance of high stress , high amplitude and the excellent heat resistance , the durability is improved compare with the shot peening process.

DAI Spring Choosing Method

?

?

Take the exactly 4 data?for Working Load, Spring Outside Diameter, Using Time, and the Deflection before choose our DAI spring .

?

For example:

1. Working Load?????????????????? ???? 100kgf

2. Spring Outside Diameter?????? 25mm

3. Using Time??????????????????????? ??? 1,000,000-time Use

4. Deflection?????????????????????????? ??? 25mm

?

Look at the below Load Curve by 1,000,000-time Use, focus on the vertical axis of Load ( kgf ) by 100kgf, find the crossing point from the horizontal axis of Outside Diameter by 25mm, we can know the load grade information.

Based on the Load Curve, by 1,000,000-time Use, when the deflection is 25mm, the below RED 25-100 spring was selected:
