Problems solved by technology

[0005] However, the above-mentioned grinding process steps will reduce the output of the product and increase the unit price of the product
In addition, the dust generated by the grinding process is easy for the operator to inhale and cause occupational injury
The above-mentioned method of increasing the thickness of the spray paint not only cannot completely solve the problem of surface defects, but also reduces the qualified rate of the product

Embodiment Construction

[0012] As mentioned above, the present invention provides a surface decoration technology for composite materials, which can effectively solve the problem of surface defects of composite materials without the problems of the prior art. The following will describe in detail with preferred embodiments.

[0013] In-mold decoration (IMD) is a way of using color printing to do color printing on a transparent film. After that, let the color-printed film undergo steps such as thermoforming and die-cutting. Finally, put it into the mold and carry out the step of plastic injection molding, so that the color film and plastic can be combined and formed to produce plastic products with beautiful and colorful appearance. Many plastic products that cannot be processed by printing and painting often use the technology of in-mold decoration to decorate their appearance.

[0014] The present invention applies the above-mentioned in-mold decoration technology to the surface decoration technol...

Abstract

The invention provides a surface decoration technology of a composite material. The printed plastic film is placed on a composite material plate, and the two are placed in a mold together. Heat is then used in the molding process to soften the composite sheet, allowing the plastic film to form with the composite sheet. After the mold is opened, the finished composite material with surface decoration can be taken out.

Description

technical field [0001] The invention relates to a surface decoration technology, in particular to a composite material surface decoration technology. Background technique [0002] The plastic casing of mobile electronic products needs to protect the precision electronic components inside and take into account the convenience of the user's movement. Therefore, it needs to be made of light-weight and high-strength plastic raw materials. Composite materials are one of the commonly used plastics. Strengthen raw materials. A composite material is a reinforced plastic material that uses short or long fibers added to plastic raw materials. [0003] The process of using composite materials to manufacture plastic casings for mobile electronic products generally involves first mixing plastic raw materials with fibers to form composite material sheets, which are then cut into appropriate sizes. Next, put the flat sheet into a mold, and carry out a molding step under heat and pressure...
