With the continuous development of science and technology, more and more mature technologies are mastered. In order to solve the same technical problem, there may be multiple ways and methods, that is, a variety of different technical solutions. Whether one or several different technical solutions are affirmative or negative, technical and economic analysis and comparison must be carried out. It can be seen that technical and economic work is an important part of the entire science and technology work, and also an important link in the technical management work. Its basic content is summarized in the following three aspects:
1 ) The formulated technical policies, technical programs, and technical measures must be in line with the party's and state's policies and policies.
2 ) The proposed technical solution is technically demanding, safe and reliable.
3 ) The technical solutions to be formulated are economically demanded, that is, the economic effects are better, and the local economic effects and overall economic effects, current economic effects and long-term economic effects, measurable economic effects, and unmeasurable economic effects must be correctly Combined.
Aluminum Die Casting Automobile AC Compressor Comp FEATURES:
During the process of die casting, molten metal is injected into two parts of a shape (the die), which are stuck together. The metal is injected under high pressure. After it has cooled, the two parts of the die come loose and the part is removed. Because the same die is used again and again, each part comes out looking exactly the same. The process of designing the die is the only technically difficult part of the operation. A lot of factors have to be considered to make sure that no air gets trapped inside the molten metal when it is injected and calculations on the draft angle have to be made to make it possible for the part to be ejected easily. This process is used in almost every industry in the world and it is unlikely that you are not surrounded by items right now that have been created through a die casting process.
• Strength and weight – Thin wall castings of die cast Automotive Parts are stronger and lighter than those possible with other casting methods. Plus, because die castings do not consist of separate parts welded or fastened together, the strength of automotive components after die casting is that of the alloy rather than the joining process.
• Multiple finishing techniques – Die cast automotive parts can be produced with smooth or textured surfaces, and they are easily plated or finished with a minimum of surface preparation.
