Advantages

   

  • Especially cost effective for producing customised, high precision flat metal parts.
  • This process presents a significant breakthrough for manufacturers, especially electronics products makers, who are producing smaller, more complex products with frequent model changes.
  • Best use for making prototypes to avoid high tooling cost and long lead-time of stamping mold fabrication.
  • Burr free & no rough edges.
  • No mechanical stresses onto parts usually caused by stamping & metal properties are not affected.
  • Ideal for thin & fragile metal/foils
  • Parts with very precise & intricate designs can be produced without difficulty.
