As the diesel engine represented by compact and efficient has gradually become the mainstream of modern ship power selection, it requires that the wall thickness of diesel engine castings become thinner and thinner, more and more spatial curved curve structures, more and more complex shapes, and higher requirements for...
Pumping unit is a kind of mechanical equipment for oil extraction, which can make oil out of the well by pressurizing. The crank is the main force bearing part of the pumping unit, and it is the bearing and transmission part that transforms the high-speed motion into the low-speed...
Investment casting, also known as lost-wax casting or precision casting, is a manufacturing process that can produce complex metal parts with high precision, excellent surface finish, and minimal machining requirements. This casting method is suitable for a wide range of materials, including ferrous and non-ferrous alloys such as steel,...
The automobile industry is the main service object of the casting industry. From a technical point of view, the casting process can provide almost any form, structure and size of vehicle parts, some of which are classic vehicle parts (such as engines) that other methods cannot provide. Based on...
(1) Improvement of dimensional accuracy of castings ① The accuracy of sand core produced by 3DP technology is ± 0.5 mm, and the deviation of casting wall thickness can be controlled within 1 mm. ② The surface roughness of castings produced by 3DP technology can reach the level of...
(1) Shorten production process 3DP directly prints sand mold/core, which saves the process of mold design, manufacturing and molding and core making, and greatly shortens the development cycle and cost of new products; It takes about 35 days to develop new products with traditional casting, while it only takes...
With its unique advantages and huge development potential, 3DP technology has attracted the attention of many enterprises. 3DP technology has the advantages of design and manufacturing integration, high flexibility, shortening the development cycle of new products and reducing the cost of research and development. The process of producing a...
Because the supercharger shell has complex structure, thin wall and multiple layers, small batch and multiple varieties, poor stability of casting surface quality and dimensional accuracy, and high rejection rate, it can not meet the user’s requirements for casting quality. In order to improve the casting quality and develop...
Compared with gray cast iron, the tensile strength of vermicular graphite cast iron is increased by about 80%, the elastic modulus is increased by about 40%, and the fatigue strength is nearly doubled. In recent years, vermicular graphite cast iron has been rapidly developed and widely used at home...
As early as 1940, when computer technology was just starting, Victor Paschkis of Columbia University of the United States put forward a mathematical model for the analysis of casting process simulation “HeatandMass Flow Analyzer”. Based on this analytical model, Victo Paschkis made a heat conduction analysis on the sand...
