A carbon fiber plate surface processing method and injection molding device used for the method

Abstract

The invention discloses a carbon fiber board surface finishing method. The method specifically includes the following steps that (1) a carbon fiber board is cut according to the required size; (2) the carbon fiber board is coated with glue to form a bonding face, and after the bonding face is baked and cured, the carbon fiber board is placed into an injection molding device; (3) plastic is molded on the carbon fiber board through the injection molding device in an injection molding mode, and meanwhile a carbon fiber pattern on a foil film of the injection molding device is transferred to the surface of the plastic; (4) a product formed by combination of the carbon fiber board and the plastic is taken out; (5) UV irradiation baking is carried out on the surface of the product, and the surface of the product is hardened; and (6) the surface of the hardened product is subjected to UV clear lacquer coating. The method that the in-mold injection molding technology and the in-mold transfer technology for the carbon fiber board are combined is adopted, and after the carbon fiber board is molded through injection molding, the surface finishing effect that the pattern transferred to the surface of the plastic is identical with a line pattern of the carbon fiber board is achieved. The manufacturing process is simple, the molding effect is good, and the effect of preventing electronic signals from being shielded is achieved.

Description

technical field [0001] The invention relates to a method for processing the surface of a carbon fiber plate and an injection molding device used in the method. Background technique [0002] The development trend of notebook computers is smaller and smaller in size, lighter in weight, and more powerful in function. In view of the thinning trend of notebook computers, domestic mainstream manufacturers have already reduced the thickness of plastic mechanism in the research and development stage, and a product made of carbon fiber has gradually come into people's sight. [0003] Carbon fiber material not only has the strong characteristics of aluminum-magnesium alloy, but also has the high plasticity of engineering plastics such as ABS; the appearance is similar to plastic, and its strength and thermal conductivity are better than ordinary ABS materials. However, carbon fiber is a conductive material. In actual use, it will act like a metal shield, causing the signals of electr...

Problems solved by technology

[0003] Carbon fiber material not only has the strong characteristics of aluminum-magnesium alloy, but also has the high plasticity of engineering plastics such as ABS; the appearance is similar to plastic, and its strength and thermal conductivity are better than ordinary ABS materials. However, carbon fiber is a conductive material. In actual use, it will act like a metal shield, causing the signals of electronic products to be unable to receive and output normally, which has affected the normal communication in people's daily life

[0004] A product combining carbon fiber board and plastic emerged as the times require. Plastic parts are used in the area of ​​receiving and outputting electronic signals, which not only avoids the risk of electronic signals being shielded, but also ensures the thinness of the product itself. However, this The surface of this product cannot present a uniform and beautiful texture effect
