Film pasting process of door plate

Abstract

The invention discloses a film pasting process of a door plate. The film pasting process of the door plate comprises the following steps that S1, the temperature of the surface on which a die is to bepasted with a film is controlled at 15-75 DEG C, the middle part is lower in temperature, and the peripheral part is higher in temperature; S2, the film is electrostatically adsorbed on the surface on which the die is to be pasted with the film; S3, an injection molding machine is divided into a front section and a back section, an injection solution is injected into the die from the middle partof the die, the speed of injection of the front section is 10%-25% of the rated speed, the injection quantity is 20%-40% of the total material quantity, and the temperature of the injection solution is 170-200 DEG C; and the speed of injection of the back section is 45%-75% of the rated speed, the injection quantity is 60%-80% of the total material quantity, and the injection solution temperatureis 200-230 DEG C; and S4, after the injection solution is cooled and molded, the die is removed, and a finished product is taken out. According to the film pasting process of the door plate, the appearance and the color of the film are more easily to control, the surface of the product is diversified, and the prepared door plate with the pasted film is not required to be trimmed and is abrasion-resisting.

Description

technical field [0001] The invention relates to the field of door panel processing, in particular to a door panel film sticking process. Background technique [0002] For kitchen cabinets, wardrobes or door cabinets, the processing steps of the door panels include cutting, milling, deburring, glue spraying, filming and other steps. The existing film sticking of the door panel is to cut the film skin of the door panel, and then carry out the lamination process with the sprayed door panel in a high-temperature vacuum environment, and the glue spraying and film sticking are performed separately. The film of this kind of door panel is not wear-resistant (air is easy to enter during the process of edge grinding of the door panel, causing the film to wrinkle), and there is a high requirement for the flatness between the film and the door panel, so that the film can be pressed under vacuum; stick it well High-quality membranes also often require trimming (the edge between the door...

Problems solved by technology

The film on this door panel is not wear-resistant (air is easy to enter during the process of edge grinding of the door panel, causing the film to wrinkle), and there is a high requirement for the flatness between the film and the door panel, so that the film can be pressed under vacuum; stick it well The film also often needs to be trimmed (the edge between the door panel and the film should be completely matched)
