Red color Industrial Compression Springs / Heavy Duty Mold Springs
ISO10243 Standard for Stamping Die
ISO 10243 red color.pdf
Discraption
Springs are widely used in stamping dies, metal
die-casting dies, plastic molds and other elastic precision
mechanical equipment, automobiles and other fields.
The material of die spring is usually chromium alloy
steel, because its characteristics of high temperature resistance,
rigidity and long service life.
According to ISO10243 standards, the color and load are as follows:
| Color | yellow | red | blue | Green |
| Load | Overweight load | heavy load | Medium load | light load |
| Service life | 3,000,000 | 1,500,000 | 200,000 |
| Compression ratio | 25% | 30% | 37.5% |
Quick Details
All of our springs are manufactured according to
ISO10243 industrial standard, and customized size is welcome.

Standard Size
We have the following standard sizes of springs in stock, generally
can be shipped within 3 working days, if it is customized ,
delivery time is generally 15-20 days.

Treatment
The following processes are the treatment
to ensure product quality.
Pressure treatment:
The spring to do more than three times of pressure
treatment, eliminating the internal stress before use, no spring
deformation, shorten the breakage and other phenomena.
Strengthened treatment:
Spring surface strengthened shot peening treatment,
improve the strength of stress concentration point, prolong the
fatigue life of the spring.
Surface treatment:
Adopt advanced color electrophoretic paint
process, conform to European SOS standard, make the product paint
surface even, adhesion is stronger.
Attention
Usually, the proportion of service life depends
on the spring and compressed, probably relations are as follows,3
points should be paid attention to prevent premature failure of the
spring:
1.Maintaining initial compression more
than 1mm
2. Prevent any other articles from the
middle of the spring
3. Keep vertical compression to prevent bending
