Method of fabricating housing, housing, and electronic apparatus
A method of fabricating housing includes steps of: providing a sheet; providing a mold including a first core and a second core, in which the first core substantially extends along a plane, and the second core is adjacent to the first core; pressing the sheet to the mold to make the sheet attach to the second core, in which the second core is fixed to the sheet; and moving the sheet away from the first core along a vertical direction perpendicular to the plane to separate the second core and the first core so as to make the second core become an internal member, in which a housing is formed of the sheet and the internal member.
1. A method of fabricating a housing, comprising:
providing a sheet;
providing a mold, wherein the mold comprises a first core and a second core, the first core substantially extends along a plane, and the second core is adjacent to the first core;
pressing the sheet to the mold to make the sheet attach to the second core, wherein the sheet and the second core are fixed to each other, wherein the step of pressing the sheet to the mold to make the sheet attach to the second core comprises:
heating the sheet before pressing; and
after pressing the sheet to the mold, a back cover and a hook structure connected to each other are formed of the heated and pressed sheet, wherein the hook structure is bended along the vertical direction to form a groove, and the second core is fixed within the groove; and
moving the pressed sheet away from the first core along a vertical direction perpendicular to the plane to separate the second core and the first core so as to make the second core become an internal member, wherein the sheet and the internal member form the housing.
2. The method of fabricating the housing of claim 1 , wherein the step of providing the sheet comprises:
heating the sheet to a first predetermined temperature.
3. The method of fabricating the housing of claim 2 , wherein the first predetermined temperature is between 300° C. and 500° C.
4. The method of fabricating the housing of claim 2 , wherein the step of providing the sheet further comprises:
heating the mold to a second predetermined temperature, wherein the first predetermined temperature is higher than the second predetermined temperature.
5. The method of fabricating the housing of claim 4 , wherein the second predetermined temperature is between 130° C. and 150° C.
6. The method of fabricating the housing of claim 1 , wherein the step of providing the sheet comprises:
applying an adhesive to the sheet to make the second core adhere to the hook structure after the sheet is heated and pressed.
7. The method of fabricating the housing of claim 1 , wherein the step of providing the sheet comprises:
applying an adhesive to the second core to make the second core adhere to the hook structure after the sheet is heated and pressed.
8. The method of fabricating the housing of claim 1 , wherein the second core is disposed around the first core, so that the hook structure is connected to an edge of the back cover after the sheet is pressed, and both the groove and the internal member are ring-shaped.
9. The method of fabricating the housing of claim 1 , wherein the first core has a top surface, the mold further comprises a third core disposed on the top surface adjacent to an inner edge of the second core, and during the period of pressing the sheet, the back cover and the hook structure are formed by the second core and the third core of the mold.
10. The method of fabricating the housing of claim 9 , wherein a dividing line is formed between the second core and the third core, and the step of moving the pressed sheet away from the first core along the vertical direction and separating the second core and the first core to make the second core become the internal member comprises:
moving the pressed sheet away from the first core along the vertical direction to make the second core fixed with the sheet and the third core connected to the second core away from the first core; and
removing the third core along the dividing line to make the second core fixed with the sheet become the internal member.
11. The method of fabricating the housing of claim 9 , wherein the material of the first core comprises metal, and the materials of the second core and the third core comprise heat-resistant plastics.
12. The method of fabricating the housing of claim 1 , wherein the first core comprises a base portion and a platform portion, the platform portion is located on the base portion, the second core is disposed at an edge of the platform portion, and after pressing the sheet to the mold, the step of making the heated and pressed sheet form the back cover and the hook structure connected to each other further comprises:
after pressing the sheet to the mold, the back cover, the hook structure and a waste portion are formed of the heated and pressed sheet, wherein the hook structure is connected between the back cover and the waste portion, and the waste portion is pressed onto the base portion; and
removing the waste portion.
13. The method of fabricating the housing of claim 1 , wherein a connecting surface is formed between the first core and the second core in the vertical direction, and the connecting surface is inclined toward the center of the first core along a separating direction of the sheet relative to the mold.
