Abstract

In one or more embodiments, a composite die includes a die face defining a protrusion and including a first metal, and a die base supporting the die face, the die base including a housing, a first filler positioned within the housing and contacting the protrusion, and a bridging member reinforcing the housing, the housing including a second metal different than the first metal.

First claim

What is claimed is:

1. A composite die comprising:
a die face defining first and second protrusions spaced apart from each other and including a first metal; and
a die base supporting the die face, the die base including a housing with a second metal different than the first metal, a first filler positioned within the housing and supporting the first protrusion, a second filler different from the first filler in composition and supporting the second protrusion, and a bridging member reinforcing the housing.

2. The composite die of claim 1 , further comprising a heat-conductive piping unit contacting the die base.

3. The composite die of claim 2 , wherein the heat-conductive piping unit includes a conformal piping portion conforming to a corresponding shape of at least one of the die face and the die base.

4. The composite die of claim 1 , wherein the first protrusion protrudes in a first direction and the second protrusion protrudes in a second direction different from the first direction.

5. The composite die of claim 1 , wherein the die face includes a three-dimensional metallic free form produced by incremental forming.

6. The composite die of claim 1 , wherein the first filler includes a third metal different than the first or the second metal.

7. The composite die of claim 1 , wherein the housing includes a number of side walls and a floor joined to the number of side walls.

8. The composite die of claim 7 , wherein at least two of the number of side walls differ from each other in dimension.

9. A composite die comprising:
a die face defining a protrusion and including a first metal;
a die base including a filler and a second metal and supporting the die face, the filler including a third metal different than the first or the second metal; and
a heat-conductive piping unit contacting the die base.

10. The composite die of claim 9 , wherein the heat-conductive piping unit includes a conformal piping portion conforming to a corresponding shape of at least one of the die face and the die base.

11. The composite die of claim 9 , wherein the protrusion includes first and second protrusions spaced apart from each other.

12. The composite die of claim 11 , wherein the first protrusion protrudes in a first direction and the second protrusion protrudes in a second direction different from the first direction.

13. The composite die of claim 12 , wherein the filler includes a first filler supporting the first protrusion and a second filler supporting the second protrusion, the first filler being different than the second filler in composition.

14. The composite die of claim 9 , further comprising a housing enclosing the filler, the housing including a number of side walls and a floor joined to the number of side walls.

15. The composite die of claim 14 , wherein at least two of the number of side walls differ from each other in dimension.

16. A composite die comprising:
a die face defining first and second protrusions spaced apart from each other;
a die base including a filler and supporting the die face; and
a heat-conductive piping unit contacting the die base.

17. The composite die of claim 16 , wherein the first protrusion protrudes in a first direction and the second protrusion protrudes in a second direction different from the first direction.

18. The composite die of claim 16 , wherein the filler includes a first filler supporting the first protrusion and a second filler supporting the second protrusion, the first filler being different than the second filler in composition.
