  • Casting Parts Quality Has A Great Influence On The Performance Of Mechanical Products
    May 04, 2018

    Mainly include appearance quality, intrinsic quality and use quality. Appearance quality refers to the Casting Parts surface roughness, surface defects, size deviations, shape deviations, weight deviations; internal quality mainly refers to the chemical composition, physical properties, mechanical properties, metallurgy of the Casting Partss, and holes, cracks, and inclusions present in the Casting Partss. Segregation and other conditions; the use of quality refers to the working durability of the Casting Parts under different conditions, including wear resistance, corrosion resistance, resistance to chilled heat, fatigue, shock absorption and other properties, and machinability, weldability and other process performance.

    Casting Parts quality has a great influence on the performance of mechanical products. For example, the wear resistance and dimensional stability of machine tool Casting Partss directly affect the accuracy of the machine tool to maintain life; various pump impeller, housing and hydraulic parts of the size of the cavity, the accuracy of the profile and surface roughness, directly affect the pump And the hydraulic system's working efficiency, energy consumption and the development of cavitation; engine block, cylinder head, cylinder liner, piston ring, exhaust pipe and other Casting Partss strength and resistance to chilling heat, a direct impact on the engine's working life.

    The market's proponents are consumers, and their demand ability becomes the only standard for enterprises to produce. Enterprises must set production capacity according to the market. Therefore, the company's market research is particularly important. It is a bridge for connecting consumers and a paving stone for final product sales.

    The market survey of Casting Parts products can allow Casting Parts companies to fully understand the situation of the Casting Parts consumer market before arranging production. Such as the demand for Casting Partss, demand types, demand manufacturers, product requirements and other information. In a large amount of information, Casting Partss manufacturers can choose their own suitable areas with a wide range of consumer markets for production; if not, companies can also have enough time to adjust production and produce Casting Partss needed for the market, thus effectively preventing the production of Casting Partss. excess.

    There are many factors affecting the quality of Casting Partss. The first is the design process of Casting Partss. When designing, in addition to determining the geometry and size of the Casting Parts according to the working conditions and properties of the metal material, the rationality of the design must be considered from the perspective of the Casting Parts alloy and the characteristics of the Casting Parts process, ie, obvious size effect and solidification and shrinkage. , stress and other issues to avoid or reduce the composition of the Casting Parts segregation, deformation, cracking and other defects. The second is to have a reasonable Casting Parts process. That is, according to the Casting Parts structure, weight and size, Casting Parts alloy characteristics and production conditions, select the appropriate parting surface and modeling, core method, set reasonable Casting Parts ribs, cold iron, riser and gating system. To ensure the quality of Casting Partss. The third is the quality of the raw materials used for Casting Parts. The quality of materials such as metal charge, refractories, fuels, fluxes, modifiers, and foundry sands, sand binders, and coatings is sub-standard, which can cause defects such as porosity, pinholes, slag inclusions, and sticky sand, affecting the appearance quality of Casting Partss. And the internal quality, when serious, will make the Casting Parts scrap. The fourth is the process operation. It is necessary to formulate a reasonable process operation procedure and improve the technical level of the workers so that the process procedures can be implemented correctly.
