Automating composite propeller blade finishing: How we helped an aerospace OEM modernise a legacy process...

This transformation not only upgraded their surface prep process but did so with a smaller footprint, a higher degree of control, and full repeatability — all critical in aerospace component manufacturing.

When a leading composite propeller manufacturer in the aerospace sector came to us, they had a clear challenge: modernise a manual wet blasting process that had been in place for a long time — while improving precision and quality.

Their existing Vapormatt manual machine had delivered decades of service, a testament to its robust build quality, but increasing demands and a growing focus on operational efficiency meant it was time for a new solution.

The goal:

✅Reduce the machine footprint

✅ Replace manual blasting

✅ Improve throughput

✅ Ensure consistent surface finishing for blades up to 2.4m (8ft) long

The solution:

Working closely with their engineering team, we delivered a Leopard Cub wet blasting system to their precise specifications — the tall, but with compact footprint, and fully automated wet blasting machine proved perfect for processing the manufacturer’s blades thanks to:

✅ Full PLC recipe control

✅ Vertical and horizontal oscillation for precise blast coverage

✅ Automation = consistent results + improved safety + labour efficiency

This transformation not only upgraded their surface prep process but did so with a smaller footprint, a higher degree of control, and full repeatability — all critical in aerospace component manufacturing.
