We are working on a new aluminum fixture. It is basically an aluminum spine with many 6061-T6 pins sticking out. Currently we drill the holes inside the spine and hammer the 5/32 6061-T6 pins inside. Is there anyway to cast aluminum with many 6061-T6 pins embedded (they will stick out after the casting)?How long are the pins? have you considered casting the pins along with the rest of the part? or is that what you are asking, it sounds, like you are talking about loading pins into the mold and having the cast spine bond with them. What casting process are you using, or are you even using a casting now, or is the spine currently rolled or extruded shapes? As mentioned on RCM, the pins will no longer be T6 after casting, if you need the T6 temper the part will have to be heat treated.Similar to the plaster answer. You will need to sacrifice your mold for each unit made. Use a thin shelled mold with the pins sticking into it. Have it in a second fixture that will hold the other end of the pins. Have you considered putting the holes in the part during the molding process? Don\'t drill them afterwards just pound in the pins.Casting aluminum is one of the least expensive ways to make metallic objects and with a little clean up work and polishing, the results are stunning and shine like the wings of the old WWII bombers. Cast aluminum melts at a hot but relatively low temperature and is easy to carve after you cast it.this may be a splash extra complicated yet promises extra advantageous element than sand casting. lost wax casting investment or ceramic shell you\'ll be able to make molds to form the wax yet investment or ceramic shell are destroyed interior the approachOther related question
