Copper castings can be divided into ordinary sand casting, metal casting, die-casting, centrifugal casting, continuous casting, investment casting, ceramic casting, electroslag remelting casting, bimetallic casting, etc. according to different casting methods. Among them, ordinary sand castings are widely used, accounting for about 80% of the total casting production. Non ferrous metal castings such as aluminum, magnesium, and zinc are mostly die castings.
The casting of copper parts is not very simple. First, the metal needs to be melted, and then the metal liquid that meets the requirements is poured into the mold. After the metal liquid cools and solidifies, it can be processed into the shape and size we want. The process of this casting is casting, but in the process of copper casting, we also need to pay attention to many things.
When casting copper alloys first, a metal mold casting method should be used. This method can facilitate the solidification of the alloy and also improve the quality of the copper castings. Moreover, it is crucial to avoid defects in castings. If metal grains can be further subdivided, it can facilitate the construction of pores and improve the airtightness of the alloy.
If there is a lot of lead in copper alloys, it is better to use metal mold casting to avoid excessive segregation of copper components. When there are many parts in copper alloys, centrifugal casting can be used. For some larger copper parts, it is better to use low-pressure casting, which can improve the density of the cast copper parts. In the process of vigorously improving the performance of copper casting products, it is necessary to fully integrate the development of product productivity, accelerate the improvement of their application performance and quality, enhance their value through correctly driving products, accelerate the reflection of their quality and other aspects of application effects, and reflect the application level of the product with advantages.
Copper castings and copper alloys can be divided into four categories based on their chemical composition: copper, bronze, brass, and white copper. They can also be divided into two categories based on their functions: general use and usage. Copper alloys can be divided into four categories based on their chemical composition: copper, bronze, brass, and white copper. They can also be divided into two categories based on their functions: general use and usage. Copper castings are based on the addition of other metal or non-metallic elements, which not only maintain the basic properties of aluminum, but also provide excellent comprehensive properties of aluminum alloys due to alloying and heat treatment. Aluminum and its alloys occupy an important position in industry, widely used in military, industrial, agricultural, transportation, and more.
Many structural components and main components of copper castings are made from castings, which are closely related to the quality and accuracy of copper. The quality of copper castings has a significant impact on the overall quality, lifespan, and accuracy of machine tools. Copper castings can also be used in valves, speakers, injection molding machines, water supply and drainage pipelines, etc.
There are various classification methods for castings: according to the different metal materials used, they are divided into steel castings, cast iron castings, aluminum castings, copper castings, copper castings, etc. And each type of casting can be further divided into different varieties based on its chemical composition or metallographic structure. Iron castings can be divided into gray iron castings, malleable iron castings, alloy iron castings, etc; According to different molding methods, castings can be divided into ordinary sand castings, metal castings, die castings, ceramic castings, electroslag remelting castings, bimetallic castings, etc. Among them, ordinary sand castings are widely used, accounting for about 80% of the total casting production. Non ferrous metal castings such as aluminum, magnesium, and zinc are mostly die castings.
Copper castings are also closely related to daily life. For example, commonly used doorknobs, door locks, radiators, plumbing pipes, iron pots, gas stoves, irons, etc. are all castings. Among them, ordinary sand castings are widely used, accounting for about 80% of the total casting production. Non ferrous metal castings such as aluminum, magnesium, and zinc are mostly die castings. The weight of copper castings accounts for a large proportion, and many structural components and major components are made of castings as raw materials, which are closely related to the quality and accuracy of the machine tool. The quality of machine tool castings has a significant impact on the overall quality, lifespan, and accuracy retention of the machine tool.
With the development of technology, the machine tool casting manufacturing industry is facing the acceleration of new frequency of manufacturing objects and the prominent personalization of processing objects. Therefore, for the machine tool industry that provides processing and manufacturing equipment, it is also required to diversify product varieties, which has become an important indicator for measuring the comprehensive performance of a machine tool industry. There are many factors that affect the quality of copper castings, which are the design process of machine tool castings. When designing, in addition to determining the geometric shape and size of machine tool castings based on working conditions and metal material properties, the correctness of the design should also be considered from the perspective of casting alloys and casting process characteristics, that is, obvious size effects and issues such as solidification, shrinkage, and stress, in order to avoid or reduce the occurrence of defects such as component segregation, deformation, and cracking in copper castings. It is necessary to have the correct casting process. According to the structure, weight, and size of the casting, the characteristics of the casting alloy, and production conditions, appropriate parting surfaces, shapes, and core making methods are selected, and casting ribs, cold iron, risers, and gating systems are correctly set. To obtain castings. The improvement of the quality of bed castings, the development of machine tool equipment manufacturing, and the overall level of improvement are beyond discussion, ultimately affecting the competitiveness of China’s machine tool equipment manufacturing industry in the market. Continuously improving the quality of machine tool castings, thereby improving the overall level of machine tool manufacturing.
