quality Forktip Casting manufacturers share casting quality
author:
quality Forktip Casting manufacturers found that casting quality mainly includes appearance quality, intrinsic quality and service quality. Appearance quality refers to the surface roughness, surface defects, size deviation, shape deviation, and weight deviation of castings; internal quality mainly refers to the chemical composition, physical properties, mechanical properties, metallographic structure of castings and the holes, cracks, inclusions, Segregation, etc.; use quality refers to the working durability of castings under different conditions, including wear resistance, corrosion resistance, shock resistance to cold and heat, fatigue, shock absorption, etc., as well as process properties such as machinability and weldability.
quality Forktip Casting manufacturers feel that the quality of castings has a great influence on the performance of mechanical products. For example, the wear resistance and dimensional stability of machine tool castings directly affect the accuracy and maintenance life of the machine tool; the size, accuracy and surface roughness of impellers, casings and hydraulic parts of various pumps, quality Forktip Casting Manufacturers found that it directly affects the working efficiency of pumps and hydraulic systems, energy consumption and the development of cavitation; the strength and shock resistance of internal combustion engine cylinder blocks, cylinder heads, cylinder liners, piston rings, exhaust pipes and other castings directly affect The working life of the engine.
