ABSTRACT:
The disclosed method forms a zinc sleeve on an insulator pin by dipping the insulator pin in molten zinc at about 450.degree.-650.degree. C. to heat and wet the insulator pin with the molten zinc, setting the hot and wetted insulator pin in a die having an open-top cavity in such a manner that an annular open-top molding cavity is defined around the insulator, the die being at about 50.degree.-300.degree. C. when receiving the insulator pin, pouring molten zinc in the annular molding cavity through its open top, and solidifying the zinc thus poured.
