As a new technology in stamping industry, fineblanking is getting more and more attentions. You shall be impressed if you ever have a look of fineblanking production line. Its high precision and unbelievable production effectioncy is amazing. We have developed new model series JC that can work with findblanking production line. Now let us start a quick knowing of fineblanking technology and JC features.

1)     What is fineblanking technology

Fineblanking is a high precision metal forming process that can be fineblanked include aluminum, brass, copper, and carbon, alloy, and stainless steels. This unique process creates parts with very tight dimensional tolerances, excellent flatness, and with very little variation from part-to-part throughout long production runs. The advantages of fineblanking are excellent dimensional control, accuracy, and repeatability through a production run; excellent part flatness is retained; straight, superior finished edges to other metal stamping processes; little need to machine details. Features as follow:

  • Cleanly sheared straight edges, with little or no diebreak
  • Small holes relative to material thickness
  • Thin web sections
  • Excellent flatness
  • Components made from rolled stock from 0.005″ to more than 0.750″ (0.13mm – 19mm) thickness
