Mold springs are essential components for consistent operation in injection molding and metal stamping. Our JIS-standard mold springs are designed to address common challenges faced in daily mold use, focusing on durability, stability, and compatibility.
1. Wide Load Range for Diverse Applications
This series includes seven types of springs, covering load requirements from ultra-light to extra-heavy.
- High compression rate springs (white) : Ideal for ejector systems that require large deflection with moderate force.
- Extra-heavy load springs (brown) : Built for high-force stamping dies, maintaining stable performance under extreme loads.
- Intermediate load options (orange, yellow, red, green) suit reset mechanisms, side core pulls, and stripper plates in both injection and stamping molds.

2. Extended Fatigue Life to Reduce Downtime
Premature spring failure is a common cause of unplanned mold stops. Our springs are tested for long-term reliability:
- Rated for up to 1,000,000 cycles at specified compression rates.
- Minimum 300,000 cycles even at higher compression ratios.
- Reduces the frequency of spring replacement and mold maintenance, minimizing production interruptions.
3. Stable Compression Performance to Prevent Part Defects
-
Inconsistent spring force can lead to flash, dimensional errors, or part sticking. Our springs feature controlled compression rates to ensure:
- Repeatable force output throughout their service life.
- Consistent mold alignment during opening, closing, and ejection.
- Helps maintain part quality by eliminating defects caused by weak or uneven spring action.
In short, reliable mold springs play a key role in improving mold stability, reducing downtime and lowering defective rate. Our JIS standard spring series provides stable, durable and universal solutions for injection molding and metal stamping industry.
