TRYSpring Features
#
TRY?Spring is especially designed for the stamping mold / plastic mold ;?TRY 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 .?TRY springs are easy for choosing because they are coating by their own different color.
# The?SUS304WPB 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??????????????????????? 3.334N
2. Spring Outside Diameter?????? 12.0mm
3. Using Time??????????????????????????? 4,000,000-time Use
4. Deflection??????????????????????????????60mm
?
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:
?
- - - -
wire diameter(mm) | Outside Diameter(mm) | inside Diameter(mm) | Free Length(mm) | constant(N/mm) |
0.6 | 12.0 | 10.8 | 60 | 0.065 |

DAI Spring Using Precautions
?
When you use DAI Spring, please observe the following instructions.
?
#
Use Over Maximum Deflection (300,000-time Condition) (Use Near Closing Position)
?
As illustrated in the drawing on the right hand, use over 300,000-time condition will be become the use around solid length. Around the solid length, since the number of active coils will become gradually coherent, the spring constant will become higher, and as illustrated, the load characteristic rises and becomes high stress, which would cause damage to products. Please refrain from using over 300,000-time condition.
?
?
?
#
Use without Initial Deflection
?
Use with any space will give impact and cause damage to spring. Be sure to use with the initial deflection of 1mm or more.
?
#
Use by Nipping Scrap or Foreign Articles
?
As illustrated in the drawing on the right side, when any foreign articles is caught in spring, such part will not work as number of active coils, and the number of active coils will substantially become reduced, which would cause higher spring constant and damage to spring. Also, the solid length will become longer.
?
?
?
?
#
Use Where the Parallelism of Mounted Surface Is Not Good
?
Bad parallelism of mounted surface would cause twisting or damage to spring. Be sure to check the parallelism.
?
#
Do not use without spring guide
?
Use without spring guide would cause twisting or damage to spring. Be sure to use spring guide such as shaft or outside diameter guide.
?
#
Using Temperature
?
?????????? When the using environmental temperature becomes higher, substantial function loss will occur. Be careful about using environmental temperature.
