4. Explosive Forming • This technique uses the energy generated by an explosive detonation to form the metal work piece. This process can deliver a great deal of flexibility in the metal-forming process. • The use of water as the energy transfer medium ensures a uniform transmission of energy and muffles the sound of the explosive blast.
