Simple Design Rules
|
|
- Draft angles are not required.
- Try to keep casting sections to a uniform thickness, avoid having several section meeting at one point.
- Avoid heavy isolated sections.
- Avoid sharp internal corners; a small radius of 0,5mm minimum is preferred.
- Most hole can be cast at clearance, reaming or tapping sizes.
- Specify all numbering, logos and lettering required and state embossed or debossed. Normally embossed within a sunken recess is preferable.
- Indicate the amount of machining allowance if required.
- Casting feed pads are normally placed at the heaviest section, in a flat area for ease of removal.
- A 0.012" feed witness is usually left on the casting after linishing, but can be removed if required.
- Avoid deep narrow blind channels or pockets if possible.
- Select a suitable alloy from the standard alloy ranges cast.
- Section sizes of less than 1,0mm can be cast locally, but preferably sections of >1,5mm are preferable.
