Foam Dynamic Fatigue Tester with Constant Force Pounding

Pounding fatigue machine that repeatedly compresses foam cushions with a loaded indenter to measure loss of height and hardness. Used by seating and mattress makers for durability validation under ASTM D3574 and ISO 3385.

Specification

A motor driven indenter foot pounds the foam sample at a set frequency for up to 80,000 cycles. Thickness and IFD loss are measured before and after the run. The machine helps compare foam grades and predict seat cushion life.

Features

• Crank driven indenter with 75 mm stroke
• Preset digital cycle counter with auto stop
• Adjustable load of 750 N for constant force fatigue
• Heavy steel frame with perforated bed
• Guarded moving parts and emergency stop
