With the development, integrated aluminum gussets for home improvement have become various, and various processing techniques have been applied to them. Series such as heat transfer printing, glaze, ink printing, mirror surface and 3D are the most popular integrated aluminum gussets for home improvement in recent years. gusset. Heat transfer printing is a process of transferring the decorative pattern on the heat transfer printing onto the surface of the decorated building material by one-time heating of the heat transfer film to form a high-quality decorative film. The thermal transfer film is made of polyethylene film as the backing paper, with a decorative layer printed on it, and the surface is coated with a protective layer, a ground color layer, a release layer and a hot melt adhesive layer. When in use, the temperature and pressure are applied to the transfer foil by heating the high-temperature silicon roller, so that the transfer layer composed of the decorative layer, the surface protection layer and the base color layer is separated from the polyethylene and transferred to the aluminum gusset plate, thereby The decorative surface pattern is formed, so that the aluminum gusset plate has excellent properties such as wear resistance, heat resistance and light resistance, the pattern is novel and beautiful, and the color is stable.

Before using the thermal transfer film, it needs to be cut into a suitable size according to the size of the aluminum gusset. In the industry, it was originally operated manually, with low efficiency and poor precision.
