I need a good recast of a broken sand casting I have. Anyone on here know who can do something like this? Sent from my SM-G955U using The H.A.M.B. mobile app
You might do a search on “casting aluminum” There was a thread on this awhile back. You might get a lead from that.
It depends a lot on how complex the part is. To make a casting you need a pattern. Because aluminum and every other metal shrinks while solidifying it’s not as simple as using the old part as a pattern. In just about all cases patterns now are made using CNC machining. It is also possible to make patterns utilizing 3D printing. However either way it would require a CAD model. This technology is not cheap. In years past you might have found a pattern maker to make a wood pattern by taking measurements from the casting you have. But as a skilled trade those guys are few and far between now. Depending on how complex the part is it may be more cost effective to have something machined from billet. It would be helpful to know what kind of part you are talking about and the appropriate sizes.
That Jonathan W guy on U Tube. cast the crankcase for a motorcycle engine. He has some very good videos showing how He done it
Look up a guy called "Crafty B" on youtube and/or instagram. He teaches classes on sandcasting and has several tutorials on youtube.
The company I work for..... Line Precision Inc. 1-248-474-5280 Just tell them Guido sent ya! Here's one we did for Mopar Performance including making the casting and doing all the machining.... That's yours truly in the picture...
Thank you sir.... We probably did around 200 of those intakes for Ma Mopar.... And they loved them... Right now, we're working on some prototype cast aluminum oil pans for Chrysler... Sorry, I can't post pictures of those... It's top secret!
Can you post up a photo of what the broken part looks like? I know of a small foundry that could do this kind of work but as mentioned above the work involved getting to the point of casting the actual part is a pretty big project. That can translate into a lot of $$$.
If the part is simple enough, he can glue it together, add a little bondo in key places to account for shrinkage, and a foundry can cast right from his original. Then it's just a bit of machine work to get back to his original size. Yes, we need pictures. .
The OP hasn't posted in over 24 hours. No pictures and no description. apparently whatever he needs casted is a big secret.
