Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a cylinder for light alloy injection-molding machine in which heat-resistance and high temperature strength of a base material for cylinder is secured and also, a manufacturing cost can be reduced compared with a conventional cylinder. SOLUTION: In the cylinder for light alloy injection-molding machine which forms a coating layer composed of erosion-resistant material on the inner surface of the base material for hollow cylindrical cylinder, the base material for cylinder is joined with the front part of the cylinder base material disposed at the injection outlet side and the back part of the cylinder base material disposed at the rear part of the front part cylinder base material in the longitudinal direction. The outer diameter of the back part cylinder base material, is smaller than the outer diameter of the front part cylinder base material. COPYRIGHT: (C)2004,JPO
