Attainable
flatness also varies with the configuration of
the casting.
Surface finish
3.2 µm. or better.
Wall thickness
1.0 mm. and up. Porosity can occur in heavy sections.
Holes
Small holes (under 5 mm) can be no deeper than the diameter.
Large holes can be deeper, but will be assessed on a one by one basis.
Draft Angels
One degree is ideal and will simulate the die-cast version of your part. The greater the draft the simpler the part and therefore the more economical.
Alloys
Aluminium AlSi7Mg
Magnesium AZ91, AM50, AM60
