close up of casting

[skippy]

As they say, a picture is worth a thousand words and this site has great pictures and info regarding the casting process. In this case it's an engine block and I'd imagine the pattern was done using cnc. Even if you're not into engines it's still worth a look.

What type of molding material are they using?

[miljnor]

wow that is an awsome sight..

looks like alot of work but I want to try it now!

damn like I have any free time.

the molding material Looks like REN shape. IT is basicaly bondo like material. you can buy it in blocks or you can buy a pourabl type (which I am guessing is what they used)

Actually, it would be a pretty sure bet that the mold material is resin bonded sand.

Cool....what is the pricing.....sure would like to have a AH 3000.....

[Mcgyver]

seen that one before, very humbling! thanks for posting it

Vipertx,
no prices on the web site for the block but the heads are au$6800.00. Rediculously expensive if you ask me, I guess if no one else makes em they can ask what the like and you either take it or leave it.

Foundryman's take:

Probably not completely cnc cut pattern, evidence of "bondo" for fillets indicates that it was assembled by hand.

The molding material is resin coated sand, there are several processes available, ie; ester cured phenolics, furans are 2 popular ones.

[ZipSnipe]

Yeah no doubt , very impressive..

I know the post is old but I would like to learn more about possibly achiving such a thing as this. Although it would be sweat to make a block I would like to achive making a head anyway.

Whats it going to take to do this ( make a head). I know thats a pretty broad question but where do I need to start at achiving this.

LOL, no takers on that question hu. Thats the best looking casting I have seen from a small shop & I wander what it takes to get this good of a result? I guess a good way to work out the steps would be to make a scaled head with this process & if you can get it to this level going bigger would be the next step. That would be a lot of shiny stuff to be melting.
