ABSTRACT:
An improved method for manufacturing an electrical heating device including the steps of placing an electric heating element comprising an electrical resistor, electrical insulation material, and a metallic jacket within a cladding tube, filling the remaining space in the cladding tube with a metal powder having a high thermal conductivity, densifying the powder after the powder is placed in the cladding tube, and subsequently sintering the powder. The improvement of the invention comprises the steps of mixing the metal powder, prior to the step of filling, from grain sizes which produce a high filling density in the cladding tube. The metal powder is then additionally densified, subsequent to the step of densifying previously carried out but prior to the step of sintering, by reducing the diameter of the cladding tube. The diameter of the cladding tube is then further reduced to compensate for shrinkage of the metal powder during the step of sintering.
