Standard notes for die-casting to feature on engineering dwg

Hey all. I just designed an Al die-casting and I want to put some standard notes on my engineering drawing.

So far I have these:
1. Standard draft angle is 3 degrees unless stated otherwise.
2. Standard wall thickness is 3mm unless stated otherwise
3. Must be free from flash and sharp edges.

Anyone else got any suggestions? I am getting a bit stuck

 

Maybe something about surface finish. Or permissable gate/spru locations or avoidances.

 

Oh yeah - good point, thanks. I now have:

1. Standard draft angle is 3 degrees unless stated otherwise.
2. Standard wall thickness is 3mm unless stated otherwise
3. Must be free from flash and sharp edges.
4. Position of gates and ejectors to be agreed before commencement of tooling manufacture.

Not too sure what to say about surface finish. Do you mean texture or surface roughness? Also I know that porosity is a biggie. Not too sure what to say on that one too.

 

Surface roughness, oh and possibly something about voids and inclusions. Cause, that would suck...

 

Also, the casting mold, if its sand, I dont think you will have ejectors.

Here are some notes from one my drawings

NOTES:
1. MATERIAL: ZAMACK #3. RAW MATERIAL AND CASTINGS TO CONFORM
TO ASTM B894-99e1.
2. NON-HEXAVALENT CHROME CONVERSION COAT PRIOR TO POWDER COATING.
3. POWDER COAT .003" THK. WITH CARDINAL PAINT NO LS4819 GREY OR EQUIVILENT.
4. POWDER COATING TO ADHERE TO ASTM D3451-01.
5. UNSPECIFIED DIMENSIONS AND DRAFT ANGLES ARE PER 3D CAD MODEL. THE MODEL IS THE MASTER.
6. MAX FLASH .005" ALL OVER.
7. NOMINAL WALL THICKNESS .050".
8. GATE VESTIGE MAX .005".
9. ALL GATE AND EJECTOR PIN LOCATIONS TO BE APPROVED PRIOR
TO DIE MANUFACTURE.
10. DIMENSIONS APPLY BEFORE PAINT OR COATINGS, INSPECT PARTS BARE.
11. POWDER COAT COVERAGE INSIDE TO BE 98%. POWDER COAT COVERAGE ON OUTSIDE TO BE 100%.
12. ALL UNSPECIFIED RADII MAX .010".

Hope this helps

I know its too late to reply. But you can add so called "Millipore Value" to ensure soundness and a dirt free Casting!

Cheers!
