Furan resin sand is generally used as the molding material for large-scale ductile iron castings produced in my country. It is produced as a single piece, with heavy pouring weight and complicated structure. It requires high quality and performance of castings. Some casting defects, especially shrin ...
This article introduces 20 kinds of metal manufacturing methods and their interpretation in detail.Die casting is a metal casting process, which is characterized by using a mold cavity to apply high pressure to the molten metal. Molds are usually made of higher-strength alloys, and this process is s ...
At present, the parting of the mold structure cannot be moved to the movable mold, and the parting of the mold reopening must be staggered with the feed. ...
At present, with the adjustment of energy structure and the improvement of environmental protection requirements, the automobile industry is developing in the direction of light weight. Data shows that for every 10% decrease in automobile quality, fuel consumption decreases by about 3% to 5%. Car li ...
In the past fifteen years, significant progress has been made in prototype replication. Initially, most RP technologies have obvious advantages in terms of speed, but due to problems in accuracy and material properties, the further development of the technology is limited. Since the emergence of RP, ...
Everyone knows that when improving machining efficiency, increasing the three elements of cutting (cutting speed, cutting depth, and feed rate) is the simplest and most direct method. ...
With the continuous development of sports and science and technology, people's living standards continue to improve, and higher requirements are placed on the quality and practicability of automobiles. In order to ensure the good performance of the car, ensure the practical applicability of the car, ...
