Abstract

The invention relates to an injection molding technology of a composite panel, which comprises the following steps: selecting a film; printing patterns on the film; printing adhesion ink on the film; punching and heating to mold the film; punching the film until the size and the shape of the film are identical to those of the panel when the film is punched to be molded; arranging the film into an injection mould and positioning; and injecting to make resin base materials adhered with the film so as to process the composite panel. The lower die of a heating molding mould used for arranging the film is a silica gel mould. The silica gel mould can smooth the drawing process, and effectively protects the ink, and the molded film has small rebound and better shaping effect and is easier to operate.

Description

technical field

[0001] The invention relates to a processing technology of a composite panel, in particular to a processing technology of an in-mold composite panel. Background technique

[0002] The traditional veneer decoration is to paste the printed film on the surface of the decorated product with double-sided tape. Due to the use of double-sided tape, it will cause the harm of organic solvents, and it is prone to delamination and warping. The overall appearance is unsatisfactory.

[0003] The surface printing of ordinary plastic parts generally has a small number of colors due to the limitation of the process, which is monotonous and dull. Contents of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a processing technology for a composite panel with firm adhesion, convenient processing and beautiful appearance.

[0005] In order to solve the problems of the technologies d...
