Characteristics and Advantages of Springs:

1. Spring Materials:

High-quality materials such as 50CrVA, 55Crsi, SUP-12, SUP-10, etc., are selected for their fatigue resistance, temperature resistance, and good toughness.

2. Material Design:

The springs are designed with a rectangular cross-section and rounded corners. The unique style of professional engineers with decades of spring manufacturing experience ensures meticulous consideration of space and overall design. Unlike rectangular springs with sharp corners, these springs minimize stress concentration during high-speed operation.

3. Stress Relief Treatment:

The springs undergo stress relief treatment at least three times, eliminating internal stress before use. This prevents spring deformation, fractures, and other issues.

4. Surface Strengthening:

The springs undergo surface strengthening treatment, resulting in a solid surface structure and improved strength at stress concentration points. This extends the fatigue life of the springs.

5. Service Life:

The service life of the springs is determined based on the stroke of the mold, ranging from 300,000 cycles to over 1,000,000 cycles.

6. Frequency of Use:

The springs can be used at frequencies of up to 200 cycles per minute. In modern mold designs, high-quality springs are essential, and JYI YUAN springs can meet your needs.
