A pounding tester machine that pounds repeatedly checks how long flexible stuff lasts, especially PU foam and shoe parts. This tester tracks wear by measuring thinning over time through constant pressure. Not just strength, it watches how much material disappears after repeated stress.

Primary Applications

Foam-making industry:

Bouncing again and again - that is what this device does to soft foams. It checks how long chair pads hold up when people drop down hard. Mattress layers get pushed in the same rough way. Car seats face the same poking, day after day.

Footwear:

Heels and midsoles go through repeated stress during testing. This checks if they keep working well after long-term use. The material must handle daily steps without flattening completely.

Leather and textile industry:

The fabric pounding tester checks heavy-duty materials when long-term squashing is part of the job. Not every material survives repeated stress, yet these methods reveal which ones stand firm.

How The Pounding Tester Machine Works

Pounding steadily, the device operates on consistent pressure commonly aligned with global benchmarks such as ISO 3385 or ASTM D3574.

The indentor:

A small round tool presses down on the material being tested. This flat tip sits just above the surface before starting. Pressure begins slowly through that blunt circle touching the piece.

The pounding cycle:

A steady beat drives the test forward. Every minute, the digital pounding tester hits seventy times repeat without pause. Each strike lands fast, one after another. Each hit during foam tests usually involves a push of 750 newtons from the indentor.

Duration:

Most of the time, a pounding tester runs through 80,000 cycles at once. That stretch often fills about 19 or 20 hours without stopping. Time piles up when machines keep moving.

Key Measurements Taken

Once the pounding stops, the lab worker checks a pair of key losses-

Resistance drop:

A measure of how little the substance fights back when pushed on.

Thickness loss:

Material squishes down more over time. Think of how a bed sags where you usually lie. That dip stays even when nothing is pressing on it anymore.
