The central housing for an advanced spotting scope by Leupold & Stevens, world’s leading producer of high-performance sports optics, is designed to offer the sharpest, brightest viewing at distances greater than possible with premium binoculars. Impressive housing specifications called for lightweight portability, absolute ruggedness and 100% waterproof construction— nitrogen filled and guaranteed for life. The scope housing requirements were met with an ideal solution – die casting magnesium (Mg) parts in order to fill the tall order. The use of a magnesium alloy for die casting allows the spotting scope housing to be as lightweight as possible while still being able to withstand outdoor elements.
The housing is produced by CWM as a hot-chamber, high-precision die cast magnesium housing, weighing just 8.0 oz. (226.8 gm) with thin-wall sections as narrow as 0.039 in. (1.0 mm). It received an award in the 2012 NADCA International Die Casting Competition in the over .5 lb. classification.
