Technical position · AMPulse analysis
Its SPD/cold spray repair has been approved under MIL-STD-3021 since 2008, and it developed an acceptance protocol sponsored by the Australian Director General of Technical Airworthiness. It owns the AMCLAD monitoring and control system for laser deposition. It has long MRO experience on the F/A-18, C-130J, CH-47, S-70B and F-35 platforms, and is part of the ASDAM group (over 1,400 employees).
Differentiation
Value Proposition
In-country repair and sustainment of high-value military aircraft components. It uses certified additive repair processes (SPD/cold spray under MIL-STD-3021 and laser additive deposition) to cut replacement costs and lead times and to improve aircraft availability.
How They Differentiate
Pairs certified additive repair (cold spray, laser deposition) with full MRO accreditation. It targets L-DED repairs that need no post-process heat treatment, using in-process microstructure control through laser rescanning.
