Abstract

A method for manufacturing a device housing, including attaching an adhesive member on an edge of a glass plate, positioning the glass plate and a metal member in an injection mold, the metal member opposite to the edge of the glass plate, and injecting molten plastic material into the injection mold, thus forming a plastic frame coating the glass plate and the adhesive member by the injection mold.

Claims

1. A method for manufacturing a device housing, comprising:

attaching an adhesive member on an edge of a glass plate;

positioning the glass plate in an injection mold; and

injecting molten plastic material into the injection mold, thus forming a plastic frame coating on the glass plate and the adhesive member by the injection mold.

2. The method for manufacturing a device housing of claim 1, wherein the adhesive member is printed on the edge of the glass plate.

3. The method for manufacturing a device housing of claim 1, wherein the adhesive member is polyurethane glue.

4. The method for manufacturing a device housing of claim 3, wherein after the adhesive member is attached to the edge of a glass plate, the adhesive member is dried;

upon injection of molten plastic material into the injection mold, the adhesive member is liquefied to provide adhesion again.

5. The method for manufacturing a device housing of claim 1, wherein the plastic frame comprises a side frame and an annular positioning portion formed on an inner surface of the side frame on which the glass plate is located and surrounded by the side frame.

6. The method for manufacturing a device housing of claim 5, wherein the adhesive member is glued to the positioning portion of the plastic frame.

7. The method for manufacturing a device housing of claim 1, wherein the plastic frame is comprised of nylon and fiberglass.

8. The method for manufacturing a device housing of claim 1, wherein a temperature of the injection mold is above about 60°

C. when the molten plastic material is injected.

9. A method for manufacturing a device housing, comprising:

attaching an adhesive member on an edge of a glass plate;

positioning the glass plate and a metal member in an injection mold, the metal member opposite to the edge of the glass plate; and

injecting molten plastic material to the glass plate and the metal member by the injection mold, thus forming a plastic frame connecting the glass plate and the metal member, and sandwiching the adhesive member between the plastic frame and the glass plate.

10. The method for manufacturing a device housing of claim 9, wherein the metal member is glued to the adhesive member.

11. The method for manufacturing a device housing of claim 9, wherein the adhesive member is printed on the edge of the glass plate.

12. The method for manufacturing a device housing of claim 9, wherein the adhesive member is polyurethane glue.

13. The method for manufacturing a device housing of claim 12, wherein after the adhesive member is attached to the edge of a glass plate, the adhesive member is dried;

upon injection of molten plastic material into the injection mold, the adhesive member is liquefied to provide adhesion again.

14. The method for manufacturing a device housing of claim 9, wherein the plastic frame comprises a side frame and an annular positioning portion formed on an inner surface of the side frame, on which the glass plate is located and surrounded by the side frame.

15. The method for manufacturing a device housing of claim 14, wherein the adhesive member is glued to the positioning portion of the plastic frame.

16. The method for manufacturing a device housing of claim 9, wherein the plastic frame is comprised of nylon and fiberglass.

17. The method for manufacturing a device housing of claim 9, wherein a temperature of the injection mold is above about 60°

C. when the molten plastic material is injected.

18. The method for manufacturing a device housing of claim 9, wherein the metal member is stainless steel.

19. The method for manufacturing a device housing of claim 9, wherein each metal member comprises a main body and a hook portion extending from an end of the main body, the hook portion engaging with the plastic frame.

20. The method for manufacturing a device housing of claim 19, wherein the metal member defines at least one connecting hole, through which molten plastic material flows during injection, and which is filled with plastic material after the molten plastic material is cooled.
