VB Tech’s head expanders provide stable, high-performance mounting surfaces for vertical vibration testing—especially when testing large or multiple items simultaneously.  Manufactured from lightweight magnesium alloy or cost-effective aluminium options, our round and square head expanders are engineered for a high strength-to-weight ratio, predictable dynamic behaviour, and seamless integration with thermal chambers for combined environmental testing.

Each VB Tech head expander is designed with real world testing in mind—whether supporting multi-item fixtures or ensuring vibration loads are distributed evenly across large surfaces. Our engineering team provides precision-calculated solutions using advanced design software, delivering head expanders that are balanced, durable, and easy to integrate into existing vibration setups.
