Abstract

A method of fabricating a housing includes: providing a metal member including a base plate and a sidewall, the base plate having an inner surface connected to the sidewall; providing a filler having a connecting surface and a first top surface; fixing the filler onto the metal member to make the connecting surface connect to the inner surface and the first top surface to respectively form first and second included angles larger than 90 degrees and smaller than 180 degrees; providing a film attached with an ink layer, and then performing a process of In-Mold-Roller Injection Molding to form a plastic on the sidewall and the filler, the ink layer attached to the plastic; and removing a part of the filler and a part of the plastic at the sidewall to form a machined surface connected to the inner surface and the upper appearance surface.

First claim

What is claimed is:

1. A method of fabricating a housing, comprising:
(a) providing a metal member, wherein the metal member comprises a base plate and at least one sidewall, the base plate has an inner surface, and the sidewall is connected to the inner surface and disposed at an edge of the inner surface;
(b) providing a filler, wherein the filler has a connecting surface and a first top surface;
(c) fixing the filler onto the metal member, so as to make the connecting surface connect to the inner surface to form a first included angle, and make the connecting surface connect to the first top surface to form a second included angle, wherein the first included angle and the second included angle are larger than 90 degrees and smaller than 180 degrees;
(d) providing a film on which an ink layer is attached, and then performing a process of In-Mold-Roller Injection Molding, so as to form a plastic on the sidewall and the filler, and the film and the plastic are pressed to make the ink layer attach to the plastic to form an upper appearance surface with the ink layer on a surface of a part of the plastic; and
(e) removing at least a part of the filler and at least a part of the plastic to form a machined surface, wherein the machined surface is connected to the inner surface to form a first machined angle, and the machined surface is connected to the upper appearance surface to form a second machined angle, wherein the first machined angle and the second machined angle are larger than or equal to 90 degrees.

2. The method of fabricating a housing of claim 1 , wherein a radius corner is formed at a junction of the connecting surface and the inner surface, and another radius corner is formed at a junction of the connecting surface and the first top surface.

3. The method of fabricating a housing of claim 1 , wherein the metal member has a first engaging structure, the first engaging structure is disposed at the base plate, the filler further has a second engaging structure, and the step (c) further comprises engaging the second engaging structure to the first engaging structure to make the filler fix onto the metal member.

4. The method of fabricating a housing of claim 1 , wherein when the filler is fixed onto the inner surface, a gap is formed between the filler and the sidewall, and the gap is filled with the plastic.

5. The method of fabricating a housing of claim 4 , wherein the step (e) further comprises removing at least a part of the filler and at least a part of the plastic over the inner surface, wherein the machined surface is connected to the inner surface.

6. The method of fabricating a housing of claim 4 , the step (e) further comprises removing at least a part of the filler and at least a part of the plastic over the inner surface, so as to form a step on the machined surface, wherein the step of the machined surface forms a stepped structure.

7. The method of fabricating a housing of claim 1 , wherein the first included angle and the second included angle are larger than or equal to 120 degrees, and smaller than or equal to 150 degrees.

8. The method of fabricating a housing of claim 1 , wherein the sidewall has a second top surface, and the first top surface and the second top surface are located on the same horizontal plane.

9. The method of fabricating a housing of claim 1 , wherein the step (c) is making the sidewall surround a side of the filler that is away from the inner surface, wherein the connecting surface is located at a side of the filler that is close to the inner surface.

10. The method of fabricating a housing of claim 1 , wherein the process of In-Mold-Roller Injection Molding in the step (d) is making the ink layer be attached to the plastic when the plastic is formed on the sidewall and the filler.
