For example, a heater of a type that may enclose the needle bottle 220 may be used to cure the resin composition injected into the needle bottle 220. For example, a coil-type heater (not shown) having a diameter larger than the diameter of the needle 220 may be used. In this case, by placing the coil-shaped heater to surround the needle bottle 220, the heater can heat the outer surface of the needle bottle 220 to cure the resin composition applied to the inner surface of the needle bottle 220.

Drawing step (S240) is to put the raw material in the drawing die (not shown) to draw a diameter to approximate the outer diameter of the predetermined needle to form a wire rod. In this drawing step (S240) it is possible to form a wire by drawing a diameter close to the outer diameter of the needle by putting a raw material, that is, a metal wire to the drawing die.

In the stagnation forming step (S250), the wire rod is cut and polished into a stagnation shape having a sharp portion at one side. That is, in the stagnation forming step (S250), the wire rod drawn in the drawing step (S240) is molded into the shape of the stagnation 210. Stagnation molding step (S250) may include a cutting step, a sharpening step and a polishing step.

In the sharpening part forming step, the sharp part 211 is sharpened by grinding the tip of the stagnation 210 formed by cutting the wire rod. That is, the sharp portion 211 may be molded by grinding the end portion of the stagnation 210 to fit the purpose of the policy.

uneven parts

31a and 32a arranged in a circular shape is prepared, After placing the needle-bonded portion 212 having the convex portion 212a formed in the first press working step S260 between the upper die 31 and the lower die 32, the upper die 31 and the lower die ( As the 32 is raised and lowered, the plurality of

uneven parts

31a and 32a press the outer surfaces of the convex portions 212a to form notches 212c in the respective convex portions 212a. By this process, the notch portion 212c and the wedge portion 212d may be formed in the convex portions 212a of the recession 210 of the present invention according to the second embodiment of the present invention. FIG. 14 is a perspective view showing a second press apparatus for explaining the second press working step of the manufacturing method of the present invention according to the second embodiment of the present invention, wherein the second press apparatus 30 is well illustrated in FIG. 14. Is shown.

The stagnation and acupuncture coupling step S280 combines the stagnation 210 and the acupuncture 220 by forcibly inserting a plurality of convex portions 212a formed in the stagnation 210 into the inside of the acupuncture bottle 220. For example, by using a fixed jig (not shown) for fixing the needles 220 and a moving jig (not shown) for fixing the stagnation 210, the moving jig is moved toward the needles 220 fixed to the fixed jig. By doing so, the needle coupler 212 of the recess 210 may be inserted into the needle bottle 220. Thereafter, the movable jig may be retracted by a distance such that the wedge portion 212d formed on the convex portions 212a of the needle-bonding portion 212 can penetrate the friction layer 230 on the inner surface of the needle-like bottle 220. have.
