With the development of automobile industry and the demand of energy saving and emission reduction, the lightweight of automobile parts is becoming more and more important. Taking FAW Casting Co., Ltd. as an example for FAW Volkswagen’s production of cast iron cylinder block, the wall thickness of 06A cylinder...
The comprehensive combination of Automobile Casting Development and digital technology can significantly improve the level of casting technology and shorten the period of product design and trial production. At present, digital manufacturing technology has been widely used in the development of automobile castings. In the stage of casting structure...
On the premise of ensuring the strength and safety performance of the vehicle, reduce the curb weight of the vehicle as much as possible, realize lightweight, so as to improve the power performance of the vehicle, reduce fuel consumption and reduce exhaust pollution. The fuel consumption per 100 km...
Casting is one of the oldest metal forming methods. About 15% ~ 20% of automobile parts are produced by different casting methods. These castings are mainly the key components of power system and important structural components. At present, European and American automobile industry developed countries have advanced automobile casting...
For the casting process design of the support table parts, first of all, from the part drawing, read the drawing, then analyze its mold type, core structure and parting surface selection, and then gradually determine the casting process parameters, design the pouring system. In this design, the casting process...
The section size of each component can be obtained by simple empirical formula according to the type, quality, size, wall thickness and casting time of casting alloy. In production, the minimum cross-sectional area of the internal sprue is 0.04cm2, and the minimum diameter of the direct sprue is generally...
1 Function and structure analysis of pouring system System pouring refers to the channel in the sand mold to guide the molten metal into the mold cavity, which is generally composed of sprue cup, direct sprue, transverse sprue, internal sprue, etc. The sprue cup receives the liquid metal, flows...
1 Inspection for fleshy defects of castings The contour of the two blanks is clear, and there is no obvious shrinkage cavity in the isolated liquid phase area, but there is an obvious “sarcoma” in one part of the blank relative to the outer contour of the outlet box,...
1 Machining allowance In order to ensure the size and accuracy of the machining surface of the parts, the thickness of the metal layer left on the machining surface and ready to be cut is called machining allowance in the casting process design. Too large or too small machining...
The pouring position of the casting is the position of the casting in the mold when pouring. The pouring position not only has an important influence on the quality of castings, but also has a close relationship with the structure of process equipment (such as pattern and core box),...
