Viscoplasticity
Viscoplasticity is a state of metal,making it behave as liquid at Hyper-Speed
A well known physical phenomenon, never before used commercially
HYPER-SPEED ACCELERATION ISTHE KEY TO VISCOPLASTICITY

Advantages of the Technology
22/04/2016 CONFIDENTIAL ©Bmax 2016 8
• Process stability eliminate failures & re-work
BETTER YIELD
• No Heat• No Smoke• No Sparks• No Oil• No Detergents
GREEN & CLEAN
• Process time is extremely short
• Handling is the bottleneck
HIGHERPRODUCTION RATE
• Lower energy consumption
• Smaller footprint• Lower cost of
quality
LOWER COSTSTABLE CORETECHNOLOGY
• High Repeatability & Cost Efficiency due to generic stability of Bmax’s core technology.
IN ADDITION TO SUPERIOR PERFORMANCES, PULSED POWER ALSO BRINGS NEW ADVANTAGES TO METAL PROCESSING
