Spin casting aluminum

Yeah, about that... No.

There is a very specific set of terminology, that helps us all stay on the same general page, as far as understanding what is being spoken about.

Patterns means one thing. Cores means another. As does Riser, Cope, and Drag.

If we all start talking about casting, it's a 'Good Thing" to al understand the terminology being used!

Plugs 'Composites', are different things than casting Patterns!

You are correct !!
I have seen many a promising development project dropped because it was not explained to the supervising executive in the words that they could understand and clearly envision for the sake of budget allocations.

Some times I have found that pictures, usually with numbers to indicate which color crayon to use for infill, often must be resorted to!

On a less sarcastic note, Patterns were often color coded, depending upon the material they were to be cast 'from', so that the finished sizes would match the shrinkage rate of the material being poured, thus you could have parts of say, Iron, Brass, and Aluminum, cast, and come out at matching sizes. The Patternmaker (A VERY skilled Trade!) would dimension the Patterns to the material used, and a lot of very high quality wood, would leave the shop slathered in colored paints so the Foundryman knew what metals they were expecting to pour in the molds made from those patterns.

In all seriousness, though, depending upon the field in question, there is often an associated vocabulary, of words that have very specific meanings, that help to keep confusion (such as just happened in this thread) down to a bare minimum. Sometimes, like listening to a Doctor, or your Dentist calling out odd words and numbers to his assistant as he probes around various parts of your anatomy, it can verge on Code, unintelligible without the knowledge of what it means, but perfectly clear to the other knowledgeable folks around.

Casting and foundry terminology is not very complex, but the various words used, are specific in their meaning and are clear to all, generally.

Been there, done that! LOL!

Cope, Drag, Pattern, Core and Draft . . all have casting specific meanings. Whether it is related to material handling, finishing or any other input to the particular component, these names can be used for various descriptions of the elements of a process.

Experience helps you to become familiar with the terminology.

Look in a Machinerys Handbook for the proper application of each detail.
The newer the versions include more process info.

What I really meant is that sometimes you need to give senior management a colouring book and a box of crayons. And even then, they might not get it........
