Investment Casting Using Melt Reservoir Loop

View page
US Patent:
6453979, Sep 24, 2002
Filed:
Nov 16, 1999
Appl. No.:
09/441259
Inventors:
Mark L. Soderstrom - Fruitport MI
Dale A. Grumm - New Era MI
Lester G. Striker - Whitehall MI
Assignee:
Howmet Research Corporation - Whitehall MI
International Classification:
B22D 1800
US Classification:
164133, 164119, 164134, 164284, 164337
Abstract:
Method and apparatus for investment casting wherein a ceramic investment mold is disposed in a chamber and communicates with a melt reservoir connected to the mold and having a reservoir volume for holding enough melt to fill the mold. The melt pour cup reservoir is communicated to the mold via an inverted loop feed gate so that the melt is fed from a lower region of the reservoir through the inverted loop feed gate to the mold upon gas pressurization of the melt in the reservoir. The loop feed gate is configured to have a loop region above the melt level in the reservoir so as to prevent melt flow from the reservoir to the more mold cavities in the absence of pressurization. While residing in the reservoir, oxides and other inclusion-forming particles in the melt can float to the upper surface of the melt, whereby the melt fed from the lower region of the reservoir to the mold via the inverted loop melt feed gate includes reduced amount of inclusion-forming particles.

Investment Casting Using Pressure Cap Sealable On Gas Permeable Investment Mold

US Patent:
60706449, Jun 6, 2000
Filed:
May 14, 1998
Appl. No.:
9/079129
Inventors:
Dale A. Grumm - New Era MI
Bradley S. Donaldson - Zeeland MI
Mark L. Soderstrom - Fruitport MI
Dennis Thompson - Whitehall MI
Assignee:
Howmet Research Corporation - Whitehall MI
International Classification:
B22D 2713
B22D 2715
US Classification:
164 661
Abstract:
A gas permeable ceramic investment mold is disposed in a casting chamber and filled with melt to be solidified via a mold melt inlet, such as for example a mold pour cup adapted to receive the melt from a melting crucible in the casting chamber. After the melt is cast into the hot investment mold in the vacuum casting chamber, a pressure cap is positioned in sealing engagement with the mold melt inlet, and gas pressure is introduced through the pressure cap to provide selective or local gas pressure on the melt in the mold without pressure cracking or other damage to the relatively fragile investment mold, while the casting chamber is maintained under relative vacuum or a different pressure from that in the mold.
