摘要： An extruder housing is formed for a double-worm or double-screw extruder by providing a steel body with a seamless one-piece structure and hot-isostatically pressing the body and the powder-metallurgical wear-resistant material lining the preferably conical bores of the housing to form a wear-resistant layer which is bonded to the steel body by a diffusion layer.
