Method and alloys for low pressure permanent mold without a coating Patent No.:US2018282842(Al)Date of Patent:2017-03-28 Inventor(s):Raymond J Donahue;Alexander K Monroe;Kevin R Anderson;Terrance M Cleary Assignee:Bru...Method and alloys for low pressure permanent mold without a coating Patent No.:US2018282842(Al)Date of Patent:2017-03-28 Inventor(s):Raymond J Donahue;Alexander K Monroe;Kevin R Anderson;Terrance M Cleary Assignee:Brunswick Corporation[US]A method and alloys for low pressure permanent mold casting without a coating are disclosed.The method for low pressure permanent mold casting of metallic objects includes preparing a permanent mold casting die that is devoid of die coating or lubrication along the die surface,preparing a permanent mold casting alloy,pushing the alloy into the die under low pressure,cooling the permanent mold casting,and removing the casting from the die.Such die coating or lubrication is not necessary because the alloys of the present invention are discovered to not solder to the permanent mold casting dies and may be pushed through even thin-walled sections of a permanent mold casting without the need for lubrication.The alloy may be pushed into the permanent mold casting die in a pressure range of 3-15 psi.The step of pushing the alloy into the permanent mold die under low pressure operates to create a permanent mold casting.展开更多
