Abstract

A tool assembly and a method for manufacturing and sealing a tool assembly for manufacturing an article includes building a tool assembly using additive manufacturing or 3D printing processes.

Claims (35)

1 . A method comprising:

receiving a tool assembly including a plurality of layers defining at least one part-cavity and plurality of cooling channels;

pouring sealant into the plurality of cooling channels;

pressurizing the sealant to a pressure for a pressurization period; and

applying a centrifugal force to the tool assembly to remove excess sealant from the tool assembly, wherein the sealant extends between the plurality of layers.

2 . The method as recited in claim 1 , further comprising:

heating the tool assembly in an oven at approximately seventy degrees Celsius for approximately four hours.

3 . The method as recited in claim 2 , further comprising:

pouring the sealant into the tool assembly while the tool assembly is at or near seventy degrees Celsius.

4 . The method as recited in claim 3 , wherein the sealant is pressurized to a pressure ranging from approximately sixty pounds per square inch to approximately one hundred pounds per square inch.

5 . The method as recited in claim 4 , wherein the pressurization period comprises at least thirty seconds.

6 . The method as recited in claim 4 , wherein the pressurization period comprises at least sixty seconds.

7 . The method as recited in claim 3 , wherein the sealant is pressurized to at least one hundred and fifty pounds per square inch for a pressurization period of at least sixty seconds.

8 . The method as recited in claim 7 , wherein the tool assembly is rotated at a rotational velocity between approximately seventy-five revolutions per minute up to approximately one hundred and twenty-five revolutions per minute for at least three minutes.

9 . The method as recited in claim 1 , wherein the sealant comprises a two-part epoxy and flowable ceramic material.

10 . A method comprising:

receiving a tool assembly including a plurality of layers defining at least one part-cavity and plurality of cooling channels;

pouring sealant into the plurality of cooling channels;

pressurizing the sealant to a pressure for a pressurization period; and

applying a centrifugal force to the tool assembly to remove excess sealant from the tool assembly at a rotational velocity between approximately seventy-five revolutions per minute up to approximately one hundred and twenty-five revolutions per minute for at least three minutes, wherein the sealant extends between the plurality of layers.

11 . The method as recited in claim 10 , further comprising:

heating the tool assembly in an oven at approximately seventy degrees Celsius for approximately four hours.

12 . The method as recited in claim 11 , further comprising:

pouring the sealant into the tool assembly while the tool assembly is at or near seventy degrees Celsius.

13 . The method as recited in claim 12 , wherein the sealant is pressurized to a pressure ranging from approximately sixty pounds per square inch to approximately one hundred pounds per square inch.

14 . The method as recited in claim 13 , wherein the pressurization period comprises at least thirty seconds.

15 . The method as recited in claim 13 , wherein the pressurization period comprises at least sixty seconds.

16 . The method as recited in claim 12 , wherein the sealant is pressurized to at least one hundred and fifty pounds per square inch for a pressurization period of at least sixty seconds.

17 . The method as recited in claim 10 , wherein the sealant comprises a two-part epoxy and flowable ceramic material.

18 . A tool assembly, comprising:

an upper half defining at least one part cavity and a plurality of cooling channels; and

a lower half defining at least one part cavity and a plurality of cooling channels,

wherein each cooling channel of the plurality of cooling channels defines a surface that includes a pressurized and cured sealant extending between one or more layers and that coats the surface.

19 . The tool assembly of claim 18 , wherein the sealant comprises a two-part high temperature cured epoxy.

20 . The tool assembly of claim 18 , wherein the plurality of cooling channels are configured to connect to a temperature control system.
