Zinc die casting was chosen to reduce cost of an antenna base for mobile radio equipment, which was originally a brass screw-machined part. Powder metallurgy was evaluated, but it couldn’t achieve the required undercuts without machining. Zamak 2 alloy was specified...

A four-piece miter gear assembly utilized zinc die casting for strength and precision. Both pinion gear shafts and housing halves are die cast net-shape, achieving full functionality without a cost penalty compared to alternative designs (thermoplastic housing/gears...

The rigidity of this part ensures the quality of retro-vision due to the absorption of the vibrations compared to engineering plastics. Note the (omega) shape for the rigidity of the assembly. Rigidity inside the envelope (volume) and reduced width of the assembly...

Wave guides are built to exacting specifications in dimensional accuracy, straightness, and flatness. Hot chamber die casting enables critical cavity sections to be cast with little or no draft; very difficult in aluminium cold chamber die casting. Flatness tolerance...

Designers of an ultra-compact scanner needed to reduce the internal envelope. The optics bracket was one component that was reduced in size but increased in functionality. The goal was to design a single mounting bracket that would accommodate a laser module, a...
