Very odd to get shrink in one cavity but not other in same mold. My first thought is one cavity is filling first and is hotter. Could be several...
Hard to tell by the pics but looks like you just need a little hotter iron and possibly some vents.
Nice job Jacob! The 3D print and the castings are are great!
That's really cool! I show my daughter stuff all the time but most of it she has no idea what she is looking at.LOL
We used to have many horizontal molding lines but they were no match for the speed and consistency of the Disa vertical molding machines. Disa...
I dont think I have ever seen a mold tilted in a high volume production environment. I have seen some other things but not tilted. The nice thing...
The old style gating had the ingates at 90 degrees and had to build up pressure to push the metal through the ingate as inertia pushed it past the...
Tapered sprue that extends past the casting with a trap at the end and a very thin ingate that runs from the bottom to the top of the casting. Not...
Are you trying to draw a pattern from the sand and it is sticking to the pattern? May have to add more draft if you are trying to draw it out of...
Lot of variables to consider and without a lot of the missing info my first guess would be to pour hotter and faster. Casting placement in the...
They probably do a lot more than just that test but that is a good test for hobby or home foundries. Kind of the same thing they used to do when...
The good news is that it doesn't really matter if it is ductile or grey iron...you can still melt it and use it as grey iron. The mag will fade...
Im thinking those would be ductile due to size and weight it would need to support. We make some covers and bases for Vestal out of grey iron but...
Really depends on what your needs are. Resin are better quality but slower and smaller. You can get a fairly decent print from filament but you...
Cant remember the name of it but there is a spray that you can spray a part with to block the reflection. I think it was called AESUB or something...
We just put one in capital expense budget at 85K...not sure we can actually justify that cost but nonetheless we are giving it a shot.LOL
If you feel good about the moisture level in your sand but do not have the strength you want, it is possible you need more clay in your sand....
I like the pre shrink dimple in the top of the riser as well...keep that area as hot as you can. The sims showed it to shrink quite well. I was...
Without going into too much detail, I played around with it a little bit. Could not see the entire gating system so played by ear on some of the...
I am curious about the shrinkage you might see with the thicker casting section and where the proper riser location would be. It would be...
