Abstract

The present disclosure describes embedding thermally-resistant flexible cabling within a metal casting during die-casting. A die-casting process may include fixing the thermally-resistant flexible cabling within a die, and die-casting the metal to form a metal casting having the thermally-resistant flexible cabling embedded within the metal casting. In some cases, the thermally-resistant flexible cabling may be utilized for grounding of the metal casting.

First claim

What is claimed is:

1. An article of manufacture containing thermally-resistant flexible cabling, wherein a portion of the thermally-resistant flexible cabling is embedded within a metal casting during die-casting, wherein the thermally-resistant flexible cabling is resistant to melting at casting temperatures for zinc aluminum alloys, and wherein the portion of the thermally-resistant flexible cabling that is embedded within a body of the metal casting is grounded to the body of the metal casting.

2. The article of manufacture of claim 1 , wherein the thermally-resistant flexible cabling is embedded within the metal casting during die-casting of a zinc aluminum alloy.

3. The article of manufacture of claim 1 , wherein the thermally-resistant flexible cabling is utilized for grounding of the metal casting.

4. The article of manufacture of claim 3 , wherein the article of manufacture further includes a grounding interconnect within the body of the metal casting, wherein the grounding interconnect has an airtight seal.

5. The article of manufacture of claim 3 , wherein the thermally-resistant flexible cabling extends through a body of the metal casting to form a grounding interconnect.

6. The article of manufacture of claim 3 , wherein the thermally-resistant flexible cabling is passed through the metal casting without post-machining.

7. The article of manufacture of claim 2 , wherein the ZA alloy is zamak 3.

8. The article of manufacture of claim 1 , wherein the zinc aluminum alloy is zamak 5.

9. The article of manufacture of claim 1 , wherein the zinc aluminum alloy is one selected from a group consisting of zamak 7 and zamak 2.

10. A die-casting process comprising:
fixing a thermally-resistant flexible cabling within a die; and
after fixing the thermally-resistant flexible cabling within the die, die-casting an alloy to form a metal casting having a thermally-resistant flexible cabling embedded within the metal casting.

11. The die-casting process of claim 10 , wherein die-casting the metal to form the metal casting comprises die-casting a zinc aluminum (ZA) alloy to form the metal casting.

12. The die-casting process of claim 11 , wherein the ZA alloy is one selected from a group consisting of zamak 3, zamak 5, and zamak 7.

13. The die-casting process of claim 11 , wherein the ZA alloy is zamak 2.

14. A process comprising:
embedding a thermally-resistant flexible cabling within a metal casting during die-casting of a zinc aluminum (ZA) alloy; and
utilizing the thermally-resistant flexible cabling for grounding of the metal casting.

15. The process of claim 14 , wherein embedding the thermally-resistant flexible cabling within the metal casting during die-casting comprises embedding the thermally-resistant flexible cabling within the metal casting during die-casting of a zinc aluminum (ZA) alloy.

16. The process of claim 14 , wherein the thermally-resistant flexible cabling extends through a body of the metal casting to form a grounding interconnect.

17. The process of claim 14 , wherein the thermally-resistant flexible cabling is internally grounded within a body of the metal casting.

18. The process of claim 15 , wherein the ZA alloy is one selected from a group consisting of zamak 3, zamak 5, and zamak 2.

19. The process of claim 15 , wherein the ZA alloy is zamak 7.
