MPF gives you the power to create complex and detailed shapes more efficiently and with less steps and equipment.
A special coil is placed near the metallic part, replacing the pusher in traditional forming. When the system releases its intense pulsed current, the coil generates a magnetic field which in turn accelerates the workpiece to hyper speed and onto the die.
At the impact, the extreme deformation speed transforms the metal into a viscoplastic state – increasing formability without affecting the original strength of the material.
Benefits Of Magnetic Pulse Forming
Product Performance
- Even material distribution
- Springback reduction
- Enables complex shapes with very fine details and sharp corners
- Extremely good capability to calibrate parts
High-quality surface finish of part
Green & Clean Process
- Uses low amounts of energy
- No pre- or post-form cleaning, no grease, no oil
Process Performance
- Higher formability (high velocity deformation)
- Less chance of tears due to friction as no contact occurs between tool and part
- Only requires a single one-sided die (1 MPF system can replace a heavy 5-step press system)
- Can be combined with any other forming technology
- Process can be applied to low conductive materials
- Cutting and perforating within same operation is possible in some cases
- Reliable and well suited to high-volume production
- Quick change over, resulting in time savings
