Has anyone done any aluminum casting before???
It seems that with all the type 1 head being cast, someone of these manufacturers might be convinced to run off some new castings for type 4 heads...... Maybe twin plug.... Bigger fins??? Better port design Better flow Lots of things could be done..... Has anyone looked into this before??? Rich |

Um....
It ain't that hard. Some CAD programs can accomodate that easily. We have used the CAD database to make a 3D SLA plastic model which is then dipped in layers of plaster. Once the plaster is hard, reinforce with sand and fill with molten metal. The SLA burns away. We used spin casting to force metal into the molds and produced very nice parts from 300/400 series stainless. Use high pressure water to blow the mold appart. The plaster will make a very nice smooth "as cast" finish and in most area, no machining will be needed. Parts look like die cast. Ken |
