Seat Foam Cushion Constant Force Pounding Fatigue Tester

Pounding fatigue tester that repeatedly compresses automotive seat foam with a flat indentor to measure loss of thickness and hardness. Used by polyurethane foam makers and seat suppliers.

Specification

A 250 mm indentor presses the foam block thousands of times at a set rate while thickness and load are measured. Hardness loss and height loss after the cycles show whether the foam will keep its comfort in vehicle service.

Features

• Pneumatic or motorised indentor with fixed cycle rate
• Cycle counter preset up to 80,000 cycles
• Perforated platen for air release from the foam
• Height measurement by digital linear scale
• Optional hardness check at 40 percent compression
