Channel and T-shape

View

This two-piece holder was developed for a precision scientific instrument. Both castings have detailed features requiring tolerances of +/-0.00025 in. Extrusion could not be used because it could not hold the tolerances, while CNC and wire EDM were not cost effective....

Capstan Retainer

View

Precision and strength are important design considerations for the minicartridge tape drive, and the capstan retainer is a good example. This part is actually two separate components cast together–a Torx head screw with an integral retainer sleeve. To produce the...
