Cast Iron Ruler Silver cm Display

[Features]
· Used when manufacturing wooden forms or dies for cast metal, and when measuring die dimensions.
When casting, molten cast iron is poured into sand depressions to harden. The mold is made slightly larger as it expands and contracts at this stage.
The contraction percentage varies depending on the metal, size, and casting factory, so the appropriate casting measure for the expansion percentage is necessary.
· Silver processing suppresses the surface reflection to make the scale easy to read.
