Fig.1: Before bending, the diode’s leads must be clamped completely to prevent stress inside the diode. Use the light grey plunger above When clamping and fixing

Fig.1a: Here the diode is not clamped, the diode easy to move and the chip inside with pressured.

Fig.2: Now the bending process begins. Only the wire which must be bent is unclamped, while the diode itself is fixed.

Fig.2a: Now the bending process starts.
The complete wire becomes stressed.

Fig.3: The bending process is done. The diode and the wires are completely clamped, no force or bending moment was created which could damage the internal diode chip.

Fig.3a: The bending process is done.
The diode and the wires are not clamped, a force and bending moment was created damaging the internal diode chip.
