High-Precision, PED Approved EV Stamping Springs

Applying too high of force or applying too little force on the blank holder can cause thinning of the panel, splitting or wrinkling, and buckling. Luckily, KALLER® KF2 Controllable Gas Springs provide just the right amount of pressure pad force on the forming stroke, and no force on the panel as the die opens — mitigating quality issues caused by using improper force and reducing scrap parts.   

Remote Automated Pressure Control for Stamping EV Components

Increase forming control, reduce the number of dies needed, and produce high-quality EV battery cases and other components while minimizing production stops with KF2 Controllable Gas Springs from KALLER. 

Benefits of using KALLER’s KF2 Gas Springs include: 

• Reduced press tool costs using just one tool for two forming applications. 
• Improved component quality with advanced forming control. 
• Increased uptime with less maintenance. 
• Elimination of parts turning in on themselves.
