Description

Technical Field

[0001] The invention relates to the field of nameplate technology, in particular to a forming process of an arc-shaped nameplate. Background Art

[0002] A nameplate is a nameplate fixed on a product to provide users with information such as manufacturer trademark identification, brand differentiation, and product parameter recording. Nameplates can be divided into paper tags, cloth nameplates, plastic nameplates, and hardware nameplates according to different manufacturing materials. Hardware nameplates are usually used in mid-to-high-end products because of their unique metal beauty. Existing hardware nameplates can be divided into stamping and die-casting according to their different processing techniques. Among them, die-cast nameplates are mostly used to produce nameplates with three-dimensional effects.

[0003] The existing curved metal nameplate with three-dimensional effect only has a logo area formed on the surface of the nameplate body. Under this structure, the three-dimensional effect of the logo area is poor, which affects the ornamental value of the nameplate. In addition, the existing metal nameplate is made of metal as a whole, which causes the entire nameplate to be too heavy, which easily affects the fixed installation of the curved nameplate. In addition, the bottom of the curved nameplate is uneven, which brings inconvenience to the gluing of the curved nameplate.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Summary of the invention

[0005] In view of this, the present invention aims at the deficiencies in the prior art, and its main purpose is to provide a forming process for an arc-shaped nameplate, which realizes precise spraying of the nameplate body by providing a first spray-shielding jig, a second spray-shielding jig, a third spray-shielding jig and a fourth spray-shielding jig, and sequentially applies a base coating, a light coating, a dark coating and a black coating, thereby improving the three-dimensional effect of the first identification area and the second identification area, so that the first identification area and the second identification area can be presented more clearly, and the provision of a bright layer makes the nameplate less likely to get dirty and brighter as a whole, and a third groove is concavely provided upwardly at the bottom of the nameplate body, and an ABS plastic part is arranged in the shape of the third groove, and the ABS plastic part is fixed in the third groove by a first double-sided tape. The provision of the ABS plastic part and the third groove reduces the overall weight of the arc-shaped nameplate, and the structure is lighter, and in combination with the provision of a pressure-holding jig, the arc-shaped nameplate can be well positioned to ensure that the arc-shaped nameplate after pressure-holding meets the pulling test.
