Aerospace Solutions

PECM is a key manufacturing process for critical aerospace components made from hard-to-machine, high-strength alloys.

Materials Machined

• Nickel-based superalloys (Inconel, Hastelloy)
• Titanium alloys
• High-strength steel
• Maraging steels for high strength and toughness

Market Sectors

• Aerospace: Turbine blades and engine components.
• Defence: Jet engine parts and military vehicle components.

Key Benefits & Numbers

• Faster Production: Reduces the machining time for complex components like airfoils by over 30% compared to conventional milling.
• Zero Tool Wear: As a non-contact process, there is no tool wear, eliminating the need for tool changes and significantly reducing costs.
• Flawless Surface Integrity: The non-thermal process produces parts with zero residual stress and no heat-affected zone, which is critical for the fatigue life of flight-critical parts.

Relevant Industry Standards

• SAE AS9100: Aerospace Quality Management System.
• MIL-HDBK-5: Military Handbook for Metallic Materials and Elements for Aerospace Vehicle Structures.
