What affect the quality of transmission castings
 2020,Feb 18|Viewed: 66

The quality of transmission castings includes appearance quality, intrinsic quality and use quality. Appearance quality refers to the surface roughness, surface defects, dimensional deviation, shape deviation, and weight deviation of the casting; intrinsic quality mainly refers to the chemical composition, physical properties, mechanical properties, metallographic structure, and holes, cracks, inclusions, Segregation and other conditions; the quality of use refers to the working durability of cast copper parts under different conditions, including wear resistance, corrosion resistance, cold and heat resistance, fatigue, shock absorption and other properties, as well as processability such as machinability and weldability. There are many factors affecting the quality of castings, which are the design process of transmission castings.

The method of hot-dip tinning of steel castings is used as a welding material for welding defects of steel castings. It is found that after welding, the weld seam is prone to cracks and the weld is severely white. In order to solve the above problems, people have adopted a comprehensive pre-preparation of the workpiece. Attempts at thermal welding have been found to help solve the problem.

Form a variety of steel casting market positioning and market strategic expansion strategies: determine the market segment in which the product is located, and make a judgment on the total demand and market capacity and prospects of China's overall casting market.

Another advantage of the investment casting method is that it can cast complex castings of various alloys, especially high temperature alloy castings. Such as the blades of jet engines, the streamlined profile and cooling cavity can hardly be formed by machining processes. Production by investment casting technology can not only achieve mass production, ensure the consistency of castings, but also avoid the stress concentration of residual knife marks after machining.

The great advantage of investment casting is that due to the high dimensional accuracy and surface finish of the investment casting, Zhengzhou Foundry can reduce the machining work, but just leave a little machining allowance on the parts with higher requirements. These castings only have grinding and polishing allowances and can be used without machining.
