Description

Manufacturing method of metal sticker {manufacturing method of metal sticker}

The present invention relates to a method of manufacturing a metal sticker, and more particularly, to clean the SUS plate at the time of manufacturing the metal sticker, and to include a dry film to easily manage the thickness deviation due to the film thickness to facilitate mass production It relates to a method for producing a sticker.

In general, a metal sticker (metal sticker) represents various patterns such as letters and pictures using stainless steel plates, and is attached to various decorative surfaces such as automobiles, MP3 players, PMPs, portable electronic devices such as mobile phones, and various home appliances. It is used to create a luxurious atmosphere.

Such a metal sticker is generally cleaned after SUS (Stainless steel) plate is applied to the surface of the photoresist, subjected to the process of exposure and development, peeling the photoresist, and after peeling after nickel and chromium plating, Bonding, scrap removal and cutting are completed.

However, the conventional metal sticker is to clean the SUS plate and then apply the liquid photosensitive liquid in a state in which the SUS plate is rotated when the photosensitive liquid is applied to the surface thereof.

Therefore, the coating of the photosensitive liquid has an advantage that can be applied several times in accordance with the application state management of the photosensitive liquid on the SUS plate.

However, when the photoresist is not applied uniformly, thickness deviation occurs, which increases the defect rate at the time of manufacture, which makes it difficult to mass-produce.

Therefore, to solve these problems, the object of the present invention is to clean the SUS plate at the time of manufacturing the metal stickers, including a dry film, easy to manage the thickness deviation due to the film thickness of the metal that can be mass-produced It is to provide a method of manufacturing a sticker.

The present invention for achieving the above object;
A first step of sorting the SUS plate, polishing the surface and the back, and washing with water; A second step of laminating the dry film after drying and preheating the SUS plate; A third step of exposing and developing the SUS plate on which the dry film is laminated; A fourth step of plating nickel and chromium on the exposed and developed SUS plate; A fifth step of peeling and drying the dry film on the SUS plate; Attaching a protective tape to the plated portion of the SUS plate, and peeling off the plated portion in which the protective tape is attached to the SUS plate to separate the semi-finished product; A seventh step of removing the protective tape of the peeled semi-finished product, cutting the semi-finished product, and then bonding silk to the back surface of the semi-finished product; An eighth step of removing the scrap of the semi-bonded product bonded the silk and sealing the semi-finished product; And a ninth step of drilling a guide hole in the semi-finished product after the eighth step.
