pneumatic foam compression fatigue tester

The HD2 Pneumatic Foam Fatigue Tester is a heavy-duty, single-station laboratory testing machine designed to evaluate the dynamic fatigue durability of flexible foam materials under repeated compressive loading. The tester applies cyclic compression to foam specimens using pneumatic actuation, simulating long-term service conditions encountered in seating, mattresses, cushioning, and interior applications. The system supports constant load testing as standard, with constant displacement mode available as an optional configuration.
