Abstract
An electrically heated spray nozzle, such as for spraying plastics, includes a highly compressed tubular heating body wound about a spray nozzle as a plurality of coil windings. The heating body has a tubular steel inner jacket containing a pair of spaced electric heating elements embedded in a high compressed powdered insulating material. A copper outer jacket encases the inner jacket and a hard solder connection joint as least as broad as the diameter of the outer jacket connects the outer jacket and hence the heating body to the nozzle. The number of coil windings per unit length of nozzle body is larger near the ends of the nozzle than near its middle. A steel wear-resistant lining may cover the surface of the nozzle bore.
