Coating process and coating device for material adhesive film decoration

Abstract

The invention discloses a coating process for material adhesive film decoration. The coating process comprises the following steps that (1) the coating range of a material is determined, and scribingmark is performed; (2) a material fixing unit is selected, and a certain gap exists between the side surface of the material fixing unit and a material male mold surface; (3) a decoration adhesive film is unfolded and fixed, and preheating and baking are performed; (4) vacuumizing is carried out, and the material is coated by the decoration adhesive film; and (5) the excess decoration adhesive film is cut. The coating process has the beneficial effects that the coating range of the material surface is increased, the coating range is expanded to the male mold surface, the structure of the material fixing unit is optimized, the plastic suction direction of the film is effectively controlled, and the purpose of coating to the predetermined position of the male mold surface is achieved. According to the coating process, the process is simple, the high-texture effect is achieved at a low cost, the problem of exposure is thoroughly solved, and the method has good commercial value and application prospect.

Description

technical field [0001] The invention relates to the technical field of film decoration, in particular to a coating process and a coating device for material film decoration. Background technique [0002] Out-of-mold decoration vacuum blister technology is to put the injection-molded product into the jig to be transferred, and then the product and the decorative film are heated, formed, and pressurized in a vacuum environment to decorate the product. It has good coating on the appearance, but it is mainly for the surface to be decorated of the required decorative material, but it is difficult to effectively decorate the non-decorative surface of the material, and the interface between the surface to be decorated and the non-decorative surface. As a result, when the material is combined with other counterparts, it is easy to reveal the unmodified material background color or white edge from the gap at the joint, so that the material decoration using out-of-mold decoration can ...

[0002] Out-of-mold decoration vacuum blister technology is to put the injection-molded product into the jig to be transferred, and then the product and the decorative film are heated, formed, and pressurized in a vacuum environment to decorate the product. It has good coating on the appearance, but it is mainly for the surface to be decorated of the required decorative material, but it is difficult to effectively decorate the non-decorative surface of the material, and the interface between the surface to be decorated and the non-decorative surface. As a result, when the material is combined with other counterparts, it is easy to reveal the unmodified material background color or white edge from the gap at the joint, so that the material decoration using out-of-mold decoration can only be limited to the outer surface. If the object is double Surface display products are difficult to implement, resulting in shortcomings in design and appearance aesthetics

[0003] In view of the problem of whitening of the above-mentioned material decoration that has been bothering the improvement of the decoration quality of related manufacturers and limiting the application and promotion of out-of-mold decoration technology, this technical field needs a coating process that is simple in process, economical and efficient, and can effectively avoid the phenomenon of no whitening and coating device
