Problems solved by technology

[0003] The traditional plastic appearance parts are injection molded first, and then undergo post-processing such as printing, painting, electroplating, etc., the color is difficult to control, and the color difference is large
Due to the high rate of post-processing defects such as spraying and electroplating, while printing is limited to flat materials, the design of traditional plastic shells is severely limited, especially for more complex heterogeneous shapes

Embodiment 1

[0029] see figure 1 , the present invention provides a kind of technical scheme: a kind of automobile control panel IMD injection molding process, comprises the following steps:

[0030] Step 1: Cut PVC or PET sheets;

[0031] Step 2: The cut sheet is placed in a 100,000-level purification workshop for purification; a 100,000-level purification workshop means that the particles per cubic meter in the workshop are controlled within 10W;

[0032] Step 3: After purification, take out the sheet and place it in a dryer for baking at 90°C for 2 hours;

[0033] Step 4: After baking, use light-curable ink to screen-print the sheet. The mesh number of the screen is 120 mesh / cm monofilament polyester screen; screen printing can be automated, with high production efficiency and UV ink light. Curing only takes a few seconds or more than ten seconds. The curing speed is very fast, and finer lines can be screen printed. The resolution is high, and the ink layer is thinner, and the printin...

Abstract

The invention discloses an automobile control panel IMD injection molding process. The automobile control panel IMD injection molding process comprises the following steps: a sheet is cut; the cut sheet is placed in a purification workshop for purification; after purification, the sheet is taken out and placed in a dryer for baking; silk-screen printing is carried out on the sheet after baking; pre-baking is carried out on the sheet after silk-screen printing; coating film is carried out on the sheet; drying is carried out after coating film; when a fixed mold and a movable mold are not closed, the prepared sheet is put into a concave part of the fixed mold, then the fixed mold and the movable mold are closed, and the concave part in the center of the fixed mold and the concave part in thecenter of the movable mold form a mold cavity, and the sheet is heated by a heating device located on the upper part of the mold cavity to perform injection molding; punching and fine scratching areperformed after injection molding; and packaging is performed after passing inspection. The automobile control panel IMD injection molding process helps reduce the subsequent processing procedures ofinjection molding, helps realize energy saving and environmental protection, and improves economic and environmental benefits; and the automobile control panel IMD injection molding process helps to improve the injection molding product rate of the automobile control panel, reduces bubbles, and ensures the transparency.

Description

technical field [0001] The invention belongs to the technical field of injection molding of automobile control panels, and in particular relates to an IMD injection molding process of automobile control panels. Background technique [0002] IMD technology belongs to the application technology of injection molding surface materials, which combines traditional injection molding technology with post-processing technology to form an integral body. It breaks through the limitations of traditional plastic shell design, and can achieve "colorful", "texture", "three-dimensional color pattern" and other effects. At the same time, it has the advantages of energy saving and environmental protection. [0003] Traditional plastic exterior parts are injection molded first, and then undergo post-processing such as printing, painting, and electroplating. The color is difficult to control and the color difference is large. Due to the high rate of post-processing defects such as spraying and...
