Embodiment Construction

[0038] Please refer to Figure 1-8. In the present invention, the method for making a keyboard by injecting keys in a metal sheet mold is to form the metal sheet on the surface of the key, so that the keyboard with the metal key is more textured. Embodiments of the method of the present invention include the following steps:

[0039] Step a utilizes drawing technology to make a metal sheet 10 form a plurality of protrusions 11, as shown in Figure 1; before being drawn, the metal sheet 10 is printed with numbers and symbols of required colors;

[0040] In step b, the metal sheet 10 having a plurality of protruding parts 11 is placed in the injection mold 20, as shown in FIG. part 11, and make the bottom edge of PC material 30 correspond to each protruding part 11 to form a groove 31, as shown in Figures 3 and 4;

[0041] In step c, put the metal sheet 10 combined with the PC material 30 inside the protruding part 11 into the punching tool 40, as shown in FIG. 4, and punch out a...

Abstract

The present invention discloses a method of making a keyboard by a key-press emitted from the internal mould of a sheet metal and the keyboard. The keyboard consists of a drawing moulding sheet metal, a key-press which is made by the emitting technology and the surface thereof is provided with a sheet metal and an elastic material layer which is combined with the hemline of the key-press groove; the surface of the keyboard has a metallic layer. The keyboard is a metallic keyboard with high texture which is capable of satisfying the requirement of the customer.

Description

technical field [0001] The invention relates to a keyboard, in particular to a keyboard with metal keys and a manufacturing method thereof. Background technique [0002] The existing keyboard production method is generally to print numbers and symbols of required colors on the PC film (Polycarbonate, polycarbonate film), and then use a vacuum-drawn mold to form a number of protrusions on the PC film. It is used as a button; then the inside of the protruding part is placed in the mold to fill the PC material, and then the PC film is stamped and cut to form the appearance of the keyboard; then the PC material is combined with the rubber layer by UV (ultraviolet) resin to form a keyboard. [0003] The applicant once proposed China Taiwan Patent Application No. 095110141, which disclosed a method of combining in-mold decoration technology to make a keyboard with a higher height and a smaller gap and the keyboard. The plastic film of a plurality of protrusions is cut into a plu...
