Problems solved by technology

Nickel is a relatively precious metal, which undoubtedly makes the cost of metal LOGO very high
And it will be more difficult to draw wire directly on the surface of nickel
All of these lead to high cost of producing high-precision LOGO
In recent years, some people have also started to use the cold extrusion method to make metal LOGO, but due to the high cost of the machine, this method has not yet been applied industrially

Embodiment 1

[0029] This embodiment is used to illustrate the LOGO with metal appearance provided by the present invention and its manufacturing method.

[0030] Preparation of plastic base parts: use Haitian HTF86 / 58*2 injection molding machine to injection mold acrylonitrile-butadiene-styrene with a number average molecular weight of 60,000 into the "sub"-shaped plastic base parts required by the LOGO, and injection molding The conditions include: using cold runners, pointing glue, one mold with two cavities, cooling with a mold temperature controller, the temperature of the front mold is 105°C, the temperature of the rear mold is 105°C, the primary injection pressure is 85 MPa, the injection speed is 65%, the position is 8.0 mm; the secondary injection pressure is 65 MPa, the injection speed is 15%, the position is 6.0 mm, the holding pressure is 70 MPa, and the barrel temperature from the first segment to the fourth segment is respectively 210°C, 230°C, 220°C, 205°C, the cooling time i...

Embodiment 2

[0035] This embodiment is used to illustrate the LOGO with metal appearance provided by the present invention and its manufacturing method.

[0036] According to the method described in Example 1, the LOGO with a metal appearance is produced, the difference is that the plastic base is obtained by composite injection molding of ABS with a number average molecular weight of 60,000 and PC with a number average molecular weight of 40,000 at a weight ratio of 1:1 , to obtain a LOGO product that not only shows the metal appearance of nickel but also shows the wire drawing effect on the surface of the copper plating layer.

Abstract

The invention provides a LOGO with metal appearance; wherein, the LOGO comprises a plastic substrate with LOGO appearance and a metal clad on at least one surface of the plastic substrate. The LOGO with the metal appearance provided by the invention adopts the plastic substrate with the LOGO appearance, so as to replace a metal substrate with normal LOGO, thereby greatly reducing the weight of the LOGO, reducing the manufacturing cost and saving the limited metal resources. On the other hand, as at least one surface of the plastic substrate (usually the positive surface of the LOGO) is provided with the metal clad; the LOGO has the excellent metallic appearance.

Description

technical field [0001] The invention relates to a LOGO and a manufacturing method thereof, in particular to a LOGO with a metal appearance and a manufacturing method thereof. Background technique [0002] LOGO is generally relatively small in size, and requires a relatively fine appearance. It usually has a sharp-edged structure and is difficult to process. The traditional LOGO with metal appearance is generally processed by metal electroforming first, and then wire drawing. At present, the production efficiency of metal electroforming process is still very low. Moreover, as the thickness of the electroformed layer increases, the efficiency of electroforming decreases continuously. In addition, due to the high requirements for the fineness of LOGO, the yield rate of electroformed products is low. At present, the yield rate of products with sharp corners and sharp corners can only reach 55%. Because nickel has the advantages of high strength and good appearance, nickel is...
