MAK M25 PISTON MAHLE TYPEWe have own professional piston factory for piston, piston crown, piston skirt. Strengthen the high coefficient of marine diesel engine and combustion of heavy oil. Long sharply against the Pistons Limited features, the structure, materials, technology and surface treatment on the Pistons all-round optimization. 1?Structure: the structure of fatigue and fatigue life of high-temperature materials such areas to improve increased to meet the heat load on the Pistons and mechanical load the ever-increasing demand, improve reliability of the use of the Pistons. The Pistons photoelastic analysis and finite element analysis shows that can improve the pin hole on the lower part of the high stress area of stress distribution, increased fatigue strength of the Pistons. 2?Material: steel roof for the E-class heat-resistant steel, used AMS U.S. and European aviation standards EN standards. From the purchase of raw materials, manufacturing processes, product assembly, every aspect of steel roof materials relevant parameters are strictly controlled and detection. After a long bolt of fatigue test. Pistons for eutectic Al-Si alloys, using the U.S. ASTM standards, deformation rate of 88 percent. 3?Technology areas: enhanced ability to ensure that special procedures. Central trough of high-frequency quenching Central quenching tank used CNC laser technology. Top steel, bolts, aluminum skirts are the United States EPSON heat treatment equipment company. 4?Surface Treatment: piston skirt certified by the French SEMT NC surface coating process. Users can choose either white or black phosphate. ? ?????????,Thanks & Best Regards, ???Zoya SRM ???Tel: +86 20 2887 9396 ????Fax:+86 20 2887 9359 ???-????Website: ??. ?????E-mail:[email protected]
