Problems solved by technology

[0005] However, when the well-known light-curable film and substrate are processed and formed (such as stamping), especially when they are bent or formed at a large angle, often due to the difference in ductility between the UV glue and the substrate, the light-cured film and substrate will The connecting surface or surface is cracked and deformed or even the UV glue is peeled off and damaged, which makes the process defect rate very high

Abstract

The present invention provides a manufacturing method and a molding apparatus for a heating molded decorative board. The manufacturing method is mainly characterized in that light curable adhesive film is molded by heating. A substrate and / or the light curable adhesive film are heated in the process of molding or before the molding to enable the light curable adhesive film to be slightly softened. The molding apparatus is mainly characterized in that a board heating device is disposed on a molding die or at one side of the molding die, so that the board heating device can be used for heating the decorative board. Accordingly, by using the apparatus and the method provided by the present invention, cracking or deformation of the light curable adhesive film can be completely prevented when molded, and the integrity of the surface lines of finished products can also be maintained, and the adhesive film can be firmly adhered on the substrate.

Description

technical field [0001] The present invention relates to a method for manufacturing a heat-formed decorative panel and its forming equipment, in particular to a casing suitable for home appliances, electrical products and electronic products, or vehicles, furniture, door panels and containers, etc. Appearance parts and manufacturing methods thereof. Background technique [0002] With the rapid development of science and technology, more and more styles of consumer electronic products have been developed. However, product appearance often becomes one of the main considerations for consumers to purchase. Therefore, the design and development of diversified decorative boards has gradually become one of the key points of the industry. [0003] The casing boards of well-known electronic products are usually attached with decorative stickers or sprayed and colored to make the appearance present different visual feelings. In addition, as the demand for texture increases, metal ca...
