AllroundLine testing system for evaluation of piston materials
Kolbenschmidt uses a ZwickRoell high-temperature testing machine to evaluate the mechanical and thermal resistance of piston materials and to compare them with each other. The Z250 SR AllroundLine testing machine is used to perform tensile tests according to ISO 6892-2 and ASTM E21. With the 3-zone furnace, operating temperatures in gasoline and diesel engines can be simulated, and tests can be performed on aluminum alloys and steel materials under real temperature conditions of +100°C to +800°C. A side-attaching, accuracy class 1 to EN ISO 9513 extensometer ensures precise strain measurement. Information gathered from the high-temperature tests allow Kolbenschmidt to draw conclusions on the strength and heat resistance of the piston materials and evaluate the suitability of the material for use in pistons.
