Head Expanders

Engineered for Precision. Built for Heavy Payloads. Designed for Results

VB Tech’s head expanders enable safe, stable vertical testing of large or multiple items with confidence. Available in round or square formats and built from lightweight magnesium or aluminium, they deliver high strength-to-weight performance with minimal resonance.

Performance Characteristics:

  • Round and square head expanders are available
  • Standard sizes up to Ø1,500mm (round) and 2,500 x 2,500mm (square)
  • FEM-optimised designs for resonance control and structural stiffness
  • Guided head expanders for high centre-of-gravity or large test items
  • Custom insert patterns and thermal chamber compatibility
  • Turnkey engineering support including FEM validation, flatness/parallelism checks, and material selection

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.
