DIFF Subgroup
B21D 26/021 Deforming sheet bodies
Introduced: January 2011
Full Title
Full titles differ between systems:
IPC:
Shaping without cutting otherwise than by using rigid devices or tools or yieldable or resilient pads, e.g. shaping by applying fluid pressure or magnetic forces > by applying fluid pressure > Deforming sheet bodies
CPC:
Shaping without cutting otherwise than using rigid devices or tools or yieldable or resilient pads, i.e. applying fluid pressure or magnetic forces (stamping using resilient pads B21D22/10) > by applying fluid pressure > Deforming sheet bodies
IPC and CPC are identically structured here. All 5 subcodes exist in both systems.
1 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 2011.
