Die casting method system and die cast product

Abstract

An embodiment in accordance with the present invention provides a method for the production of castings with incorporated tubes, where the castings are from cast metal and where the tubes are cast-in with a superheated molten metal. Multiple tubes or a plurality of designs may be incorporated into the invention. The present invention also provides a method for cooling the interior of a cast product before, during, and after the product is cast.

1 . A method for production of a casting incorporating a passage comprising: 
 disposing at least one tube in a mold to form the passage; and    casting a metal around the tube, wherein a portion of the tube is deformed during casting.    
   
   
       2 . The method according to  claim 1 , wherein the metal is a semi-solid metal.  
   
   
       3 . The method according to  claim 1 , wherein the tube comprises steel.  
   
   
       4 . The method according to  claim 1 , wherein the mold comprises guides matching the direction of the tube through the casting.  
   
   
       5 . The method according to  claim 1 , wherein the metal is an aluminum alloy.  
   
   
       6 . The method according to  claim 1 , wherein the portion of the tube is crimped or clamped.  
   
   
       7 . The method according to  claim 1 , further comprising treating at least a portion of a surface of the tube.  
   
   
       8 . The method according to  claim 7 , wherein the treating comprises spraying the surface with an aluminum composition.  
   
   
       9 . The method according to  claim 7 , wherein the treating comprises shot blasting.  
   
   
       10 . The method according to  claim 7 , wherein the treating comprising metal plating.  
   
   
       11 . The method according to  claim 1 , further comprising passing fluids through the tube before, during, or after casting.  
   
   
       12 . A means for production of a casting incorporating a passage comprising: 
 disposing means that places at least one tube in a mold; and    a casting means that casts a metal around the tube.    
   
   
       13 . The casting means according to  claim 12 , wherein the metal is a semi-solid metal.  
   
   
       14 . The casting means according to  claim 12 , wherein the tube comprises steel.  
   
   
       15 . The casting means according to  claim 12 , wherein the mold comprises guides matching the direction of the tube through the casting.  
   
   
       16 . The casting means according to  claim 12 , wherein the metal is an aluminum alloy.  
   
   
       17 . The casting means according to  claim 12 , wherein the tube is crimped or clamped.  
   
   
       18 . The casting means according to  claim 12 , further comprising treating at least a portion of a surface the tube.  
   
   
       19 . The casting means according to  claim 18 , wherein the treating comprises spraying the surface with an aluminum composition.  
   
   
       20 . The casting means according to  claim 18 , wherein the treating comprises shot blasting.  
   
   
       21 . The casting means according to  claim 18 , wherein the treating comprising metal plating.  
   
   
       22 . A cast product, comprising: 
 at least one tube; and    metal cast around the tube.    
   
   
       23 . The method according to  claim 1 , wherein the tube comprises aluminum.  
   
   
       24 . The method according to  claim 1 , wherein the metal is a liquid metal.  
   
   
       25 . The method of  claim 1 , wherein the casting is hollow.  
   
   
       26 . The method of  claim 1 , wherein the mold comprises openings to pass a cooling medium through the casting.  
   
   
       27 . The method of  claim 1 , wherein the casting is steel or aluminum.  
   
   
       28 . A method for production of a casting incorporating a passage comprising: 
 disposing a tube in a mold to form the passage, the tube having a first end and a second end;    closing the tube at the first or second end;    deforming a portion of the tube during casting; and    casting a metal around the tube to form a product.    
   
   
       29 . The method according to  claim 28 , wherein the second end is closed during casting and is opened after casting by a metal treatment.  
   
   
       30 . The method according to  claim 28 , wherein a cooling medium is disposed in the tube.
