Abstract
An exemplary mold assembly includes a mold providing a cavity, and a heating element configured to heat a first portion of the mold at a first rate to melt a first amount of metal powder within the cavity, and further configured to heat a second portion of the mold at a different second rate to melt a second amount of powder within the cavity. The heating element includes a portion on a first side of the cavity and a portion on an opposing, second side of the cavity. The heating element is configured to receive the mold such that the heating element extends circumferentially about an entire perimeter of the mold.
Claims13
A mold assembly, comprising:
- a mold providing a cavity;
- and
- a heating element configured to heat a first portion of the mold at a first rate to melt a first amount of metal powder within the cavity, and further configured to heat a second portion of the mold at a different second rate to melt a second amount of powder within the cavity,
- the heating element including a portion on a first side of the cavity and a portion on an opposing, second side of the cavity,
- wherein the heating element is configured to receive the mold such that the heating element extends circumferentially about an entire perimeter of the mold,
- wherein the heating element is configured to heat the first portion at the first rate and second portion at the second rate without moving the mold,
- wherein the heating element is configured to control a cooling of the mold by shutting off a first area of the heating element before another second area of the heating element without moving the mold relative to the heating element.
A cast component assembly comprising:
- a component, wherein at least a portion of the component is formed from a metal powder that has been melted and cooled within a mold cavity without moving the component relative to the mold cavity,
- wherein the metal powder has been melted using a heating element on a first side of the component and a second heating element on an opposing, second side of the component,
- wherein the heating element is configured to receive the mold such that the heating element extends circumferentially about an entire perimeter of the mold,
- wherein the metal powder is cooled at different rates by shutting off a first area of the heating element prior to a second area of the heating element.
