Target Audience: This technical guide is written for automotive distributors, engineers, repair workshops, and OEM buyers sourcing replacement gas springs or custom lift supports.
Eliminate Slamming and Vibration
A soft close damper (or hydraulic buffer) contains no pressurized nitrogen gas. Instead, it is filled entirely with specialized hydraulic fluid. Its sole purpose is to absorb kinetic energy, slowing down moving objects safely and quietly.
Engineering the Perfect Deceleration
By altering the internal orifice size and fluid viscosity, we can engineer custom deceleration curves:
- Linear Damping: Constant resistance throughout the entire stroke.
- Progressive Damping: Resistance increases exponentially as the damper compresses, ideal for heavy, fast-moving machinery doors.
