Low Contact Force (LCF) gas springs are designed to reduce excessive shock loads, high noise levels and extreme pad bounce, all factors that lead to high press maintenance costs and noise pollution.
The LCF (Low Contact Force) series makes up the future generation of nitrogen gas springs. This innovative gas spring series is engineered to address the major problems facing metal stampers today: excessive shock loads, high noise levels and extreme pad/blank-holder bounce, all factors that lead to high press maintenance costs and noise pollution.
The LCF series reduces shock loads by as much as 50 % compared to standard gas springs. They deliver a gradual force build-up and smooth acceleration so there’s less impact on gears and bearings and less wear on drive components.
The payoff is reduced press maintenance.
The LCF Series lowers noise levels significantly, with a higher reduction in sound pressure level compared to standard gas springs. Its lesser impact force results in these lower noise levels and makes these springs a cost effective alternative to erecting noise enclosures. The payoff is a quieter, safer and healthier working environment.
The LCF Series decreases pad/blank-holder bounce, allowing improved part transfer efficiency, increased production rates and reduced scrap. A gradual force increase and return result in smoother pad/blank-holder operation. The payoff is higher production rates.
Because LCF gas springs mount directly to the die and are independent from the press, all benefits travel with the tool.
