Hot stamping with Gas Springs Solution


Hot stamping (press hardening or hot press forming), is a method of stamping metals like high strength steels - and has several benefits like potentially reducing weight by using thinner sheets of metal & single parts can have different strength levels which is useful for crash absorption. The problem with hot stamping is the dirty environment, which can affect the service life of gas springs. Fortunately, KALLER has a simple and effective solution: Heavy Duty Protection (HDP) covers.


Hot Stamping high strength steels has been somewhat of a trend with benefits like potentially reducing the weight of pressed parts and is seen in OEM Automotive Standards. It has, for example, been used as a viable solution to protect battery packs in electric vehicles, or EVs. Naturally, hot stamping comes with a dirty & dusty environment- resulting in a shorter lifespan of Gas Springs from the dust.


Fortunately, KALLER has a simple solution to protecting Gas Springs from dirty environments to double their lifetime:
