Claim 6:
7. The method of claim 5, wherein dividing the ith area into ki blank holder areas in the radial direction based on the width of the flange area corresponding to the sheet material and the thread parameter of the pressure sensor comprises:
in a case that a ratio of the width of the flange area corresponding to the sheet material to a thread diameter d0 of the pressure sensor is greater than 2 and less than 4, dividing the ith area into ki blank holder areas in the radial direction, where ki=1, and a width of the blank holder in the radial direction is equal to a width of the ith area in the radial direction; and
in a case that the ratio of the width of the flange area corresponding to the sheet material to the thread diameter d0 of the pressure sensor is greater than or equal to 4, dividing the ith area into ki blank holder areas in the radial direction, where ki≥2, a total width of the ki blank holder areas in the radial direction is equal to the width of the ith area in the radial direction, wherein a width of a blank holder area in the radial direction is greater than 2d0.
