Abstract
The disclosure relates to methods of fabricating of a graphite powder mold, including: applying a base layer to an exposed surface of a mold having one or more features; depositing a graphite powder onto the base layer to fill the one or more features; applying a cover layer onto an exposed surface of the graphite powder, wherein the cover layer and the base layer join at intersecting surfaces encasing the graphite powder to form the graphite powder mold having one or more raised features
Claims23
A method of forming a graphite powder mold, comprising:
- applying a base layer to an exposed surface of a mold having one or more features;
- depositing a graphite powder onto the base layer to fill the one or more features;
- applying a cover layer onto an exposed surface of the graphite powder, wherein the cover layer and the base layer join at intersecting surfaces encasing the graphite powder to form the graphite powder mold having one or more raised features.
An article, comprising:
- a first surface;
- a second surface opposing the first surface;
- a side wall connecting the first surface to the second surface,
- wherein the side wall defines a thickness of the article,
- wherein the first surface comprises one or more raised features,
- wherein the second surface comprises one or more depressed features corresponding to the one or more raised features of the first surface,
- wherein the first surface, second surface and the sidewall enclose a volume;
- and
- a graphite powder filling the volume.
A method of forming a graphite powder mold, comprising:
- pouring a mixture of graphite powder and binder into a cold pressing die;
- applying a force to compress the mixture into a graphite powder disk;
- removing the graphite powder disk from the die;
- machining the graphite powder disk to form one or more features on the graphite powder disk.
