Problems solved by technology

The plastic injection of the surface decoration parts of this structure is easy to produce flow marks, impact marks, fusion lines, film lamination lines, ink, etc. on the surface of the product, which will be worn or scratched after a long time, and the appearance effect is poor; color parts Difficult to control, large color difference; unable to achieve silver injection, increasing cost and causing pollution; after plastic parts are produced, spraying, printing, electroplating, electro-engraving and other post-processes are required, and the processing defect rate is high; if two-color injection is used, mold processing costs High, product changes are limited; products such as multi-color combinations require multiple pieces to be disassembled, which increases the difficulty of online assembly

Abstract

The invention relates to a surface decoration piece (IMD) and the production process of the surface decoration piece, which is in particular widely used in the information technology products, household appliances, electronic products, personal computers, car accessories and so on and belongs to the technical field of injection molding decoration. The invention is characterized in that the screen-printing of ink patterns is adopted on the reverse side of a transparent sheet. The ink pattern is disposed between the injection molding layer sheet and the formed transparent sheet, which is integrated through the drying, cutting, molding and the injection molding. With the invention, the production time can be shortened and the costs can be reduced with the improvement of product quality and the enhancement of the scratch resistance of the products. With strong solvent resistance, excellent three-dimensional sense, the patterns are clear with excellent anti-light and moisture proof performance. The graphic, logo and color can be changed at any time without the need to replace the die. The convex bubbles of the function keys are uniform with good feel, in which the life expectancy can be up to one million times. The printing precision of the products with three-dimensional shapes is accurate and the error is small.

Description

technical field [0001] The present invention relates to a surface decoration (IMD) and its manufacturing process, which is widely used in information products, household appliances, electronic products, personal computers, automobile accessories, etc., and belongs to the technical field of molding and injection molding decoration. Background technique [0002] The traditional surface decoration is to screen print the pattern on the surface of the workpiece or on the surface of the injection molded equipment. The plastic injection of the surface decoration parts of this structure is prone to produce flow marks, impact marks, fusion lines, film lamination lines, ink, etc. on the surface of the product, which will be worn or scratched after a long time, and the appearance effect is poor; color parts It is not easy to control, and the color difference is large; it is impossible to achieve silver injection, which increases the cost and causes pollution; after the plastic part is ...
