Die Castings for Automotive Parts 370158

ADAPTABILITY of die castings to economical manufacture, to close dimensions, to complex shapes, and to thin sections is stressed.
Die-casting alloys are reviewed, emphasizing the suitability of the zinc alloys in cost, physical properties, and die cost, along with their limitations as to temperature and otherwise.
A discussion of applications to automotive grilles includes comparison with other methods of producing these parts and a description of the built-up type of die-cast grille.
Steering-wheel applications considered include hubs, horn rings, and light switches. Windshield-frame parts, louvres, radio grilles, lamp mountings, body-interior parts, horn bodies, and a number of chassis applications also are discussed.
A review of finishing processes and notes and suggestions on design conclude the paper.
