Abstract

The invention discloses a manufacturing method of a water transfer keycap for a computer keyboard. The manufacturing method comprises the following steps that 1, a keycap injection mold is taken; 2, ABS raw materials are added into an injection molding machine to be subjected to temperature-preservation and pressure-preservation injection molding by means of the keycap injection mold to obtain a keycap; and 3, the keycap obtained in the step 2 is subjected to water transfer processing to obtain the finished keycap. According to the water transfer keycap which is used for computer keyboard andmanufactured by means of the method, the surface of the keycap is covered with a pattern, keycaps of the same keyboard are processed in the same batch, therefore, it is guaranteed that the pattern effects of the keycaps after water transfer are matched, and the usage requirement of daily life and work of people on the computer keyboard is met; and meanwhile, the surface of the keycap is provided with a protection layer which can prevent the pattern from being worn, and therefore the service life of the keycap is prolonged.

Description

technical field [0001] The invention relates to the field of key cap processing, in particular to a method for making a computer keyboard water transfer key cap. Background technique [0002] The keyboard is one of the peripherals of the computer. The operation of the computer and the input of characters can be controlled through the keyboard. Usually, a keycap is installed on the computer keyboard. Along with people more and more popularizing to the use of computer and keyboard in daily work and life, the outward appearance of computer keyboard is also along with constantly changing, and the outward appearance of computer keyboard is also paid more and more attention to by people. The keycap is the main component of the keyboard, and the appearance of the keyboard is mainly reflected by the keycap. Existing keycaps are usually made of acrylonitrile-butadiene-styrene (ABS) plastic injection molding, basically one color or two colors, the color is monotonous, not beautiful, ...
