4 The CF eries is the future generation of nitrogen gas springs. This innovative series is engineered to address three major problems facing metal stampers today: excessive shock loads, high noise levels and extreme pad bounce. All factors that lead to high press maintenance costs, low productivity and noise pollution.

The payoff is reduced press maintenance. The CF eries lowers noise levels significantly, with a 2% or higher reduction in sound pressure level compared to standard gas springs. The payoff is a quieter, safer and healthier working environment. The CF eries decreases pad bounce, allowing improved part transfer efficiency, increased production rates and reduced scrap. And because CF gas springs mount directly to the die and are independent of the press, all benefits travel with the tool.
