Zinc Die Cast Cable Assemblies

CAST YOUR LOT WITH LOOS CUSTOM ZINC DIE CASTINGS

ADVANTAGES OF ZINC:

END FITTINGS ON CABLE ASSEMBLIEs SMALL PART DIE CASTINGS

· Holds break strength on cable • Less expensive than machined parts

· Less expensive than swaging • Intricate shapes and undercuts

· Intricate & special threaded parts • Elimination of secondary operations
