Abstract

PURPOSE:To perform the titled operation so that its manufacture is simple, quality is made not to be deteriorated, cost is low and mass production is possible, by a method wherein after a conductive metallic substrate plated layer has been applied, a main plated layer such as a nickel plated layer is clad over the same substrate plated layer through an electrolytic plating method having said substrate plated layer for its electrode. CONSTITUTION:Pattern molding of a button body 5, whose top is provided with a decorative part 1 and a bull's-eye-like recessed part 2 and bottom is provided with a sunken part 4 obtained by surrounding with protruded stripe 3 respectively, is performed through a thermoplastic hard synthetic resin material. A fitting leg 7 whose base end is provided with a collarlike part 6 is constituted through a metallic material. The fitting leg 7 is fixed to the button body 5 unremovably by a device stopping the collarlike part 6 forcibly by fitting the collarlike part 6 in the sunken part 4 and folding down the protruded stripe 3 inwardly by caulking through heating. Then a conductive metallic substrate plated layer 8 based on electrolysis is applied to the external surface of the button body and fitting leg 7. In addition to the above, a main plated layer 9 of nickel is clad over the same substrate plated layer 8 through an electrolytic plating method having said substrate plated layer 8 for its electrode. Then a pattern 10 of a different color or quality with that of the button body 5 is provided in the recessed part 2 by casting synthetic resin such as epoxy resin into the recessed part 2, through which finished product (a) are obtained.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for manufacturing clothing buttons such as hook and dot buttons, which are made of a thermoplastic hard synthetic resin material and have decorative parts on the upper surface and protrusions on the lower surface. A button body having respective surrounded recesses is molded, and a mounting leg with a flange at the base end is made of a metal material, and then the flange is fitted into the recess and the protrusion is inserted. The mounting leg is irremovably fixed to the button body by means of folding the strip inward by heating and caulking and pressing the brim, and then a conductive metal base is electroformed on the outer surface of the button body and the mounting leg. This relates to a method for producing a button, which is characterized in that after the plating layer is resistant to adhesion, a main plating layer such as a Nilaglu layer is deposited on the base plating layer by electrolytic plating using the base plating layer as an electrode. .

[Conventional technology]

Conventionally, there was no method for manufacturing this type of button.

[Problem that the invention seeks to solve]

In the button manufacturing industry, technological innovations are being carried out with the aim of simplifying manufacturing, not reducing quality, lowering costs, and enabling mass production.

[Means for solving problems]

In the present invention, a button body is molded using a thermoplastic hard synthetic resin material, and has a decorative part on the upper surface and a recessed part surrounded by two protrusions on the lower surface, and a flange-like part at the end is molded using a metal material. The mounting leg is attached to the button body by means of constituting the leg, and then fitting the flange-like part into the recessed part and folding the protrusion inward by heating and caulking the flange-like part to hold the flange-like part. After fixing the button irremovably, a conductive metal base plating layer is applied by electroforming to the outer surface of the button body and the mounting leg, and then Nilaglu plating is applied on the base plating layer by electrolytic plating using the base plating layer as an electrode. The purpose is to deposit a plating layer, thereby achieving the above goals.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings. First, a decorative part (11
Then, a button body (5) is molded, each having a serpentine recess (2) and a recess (4) surrounded downward by a protrusion (3).

In addition, separately from this, a flange-shaped part (6
) with mounting legs (constituting the force.

After that, the button is pressed by fitting the flange (6) into the concave part (4) and folding the protrusion (3) inward by heating and caulking the flange (6). The mounting leg (7) is permanently fixed to the main body (5).

Next, a conductive metal base plating layer (8) is adhered to the outer surfaces of the button body (5) and the mounting leg (7) by electroforming.

Furthermore, a main plating layer (9) of nickel is deposited on the base plating layer (8) by electrolytic plating using the base plating layer (8) as an electrode.

After that, a synthetic resin such as epoxy resin is poured into the recess (2) to create a pattern C that is different in color or different from the button body (5).
1 liter was provided, and the finished product (a) was obtained by climbing on it.

[For production]

As described above, the present invention greatly contributes to achieving the goals of simple manufacture, no deterioration in quality, low cost, and the possibility of mass production.

〔Effect of the invention〕

As described above, the present invention has excellent effects that can fully achieve the intended purpose.
