High Pulse Power Background

22/04/2016 CONFIDENTIAL ©Bmax 2016 3

“High Pulsed Power (HPP) refers to a brief discharge of concentrated electrical energy that generates a huge electrical power, much like in thunderstorms.”

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
