Advantages of Precision Machining

Precision machining is a rigorous and complex process, which is widely used in the processing of various parts, ranging from mobile phone parts to aerospace equipment parts. Why do these people have to deal with a part in this process? What are the advantages of precision machining? Ordinary processing can not produce high-precision products, because [...]

Steel Casting Part

Steel Casting part is to melt cast iron or steel and pour it into the pre-prepared mold shell. After cooling, removing the shell will become the part blank. This process reduces the amount of processing, especially for parts with more curved surface, which is difficult to process. Casting solves the processing difficulties and improves the [...]

About Mold Casting

Mold casting is a widely used form of casting. As the name suggests, sand is used to make molds. Sand casting requires placing a finished part model or a wooden model (pattern) in the sand, then filling the pattern around the sand, and unpacking the pattern to form the mold. In order to remove the [...]

Difference between Castings and Forgings

1. Differences in mechanical properties After the forging is processed twice, there will be a hardening process, which will lead to fine arrangement, no directional mechanical properties, better than the casting. 2. Different moulding methods Castings are melted by melting furnace, poured into the model, cooled and formed; forgings are formed by repeated restrictions under [...]

Development Trend of Castings

China is a large casting country, and the domestic castings are seriously over-produced. However, China’s severe overcapacity of castings refers to the overcapacity of low-end castings in China. It is difficult for China’s high-end castings to meet the needs of the market. Therefore, China’s The demand for castings transforms the production capacity of low-end castings [...]

Factors Influencing the Solidification Mode of Castings

There are many ways to solidify castings. In the process of solidification of castings, the section is generally divided into three sections: 1.solid phase zone 2.coagulation zone 3.the liquid phase zone.the greater influence on the solidification zone is the width and narrowness of the solidification zone, and the solidification mode is divided accordingly. First, intermediate [...]

How to Repair the Casting Defection

The most fundamental focus of the solution to repair the casting defection in castings is "heat balance." The method is: (1) In the thick and hot joints formed by the machine tool casting structure, rapid solidification is carried out, artificially causing the basic balance of the temperature field throughout the casting of the machine tool. [...]

Inspection of Internal Defects in Castings

For internal defects, commonly used non-destructive testing methods are radiation detection and ultrasonic testing. Among them, the radiation detection effect is the best, it can obtain an intuitive image reflecting the type, shape, size and distribution of internal defects, but for large castings with large thickness, ultrasonic testing is very effective, and the position of [...]

Detection of Casting Surface

Detection of casting surface: 1) Liquid penetration test Liquid penetrant testing is used to inspect various opening defects on the surface of castings, such as surface cracks, surface pinholes, and other defects that are hard to find by the naked eye. The commonly used penetration test is coloring detection, which wets or sprays a colored [...]

Defects of Sand Casting

Defects of Sand casting include: cold isolation,insufficient pouring, blowhole, sand bonding, sand inclusion, sand hole, sand swelling, etc. 1) Cold insulation and insufficient pouring The liquid metal filling capacity is insufficient, and the molten metal stops flowing before the cavity is filled, which will cause the casting to have insufficient or cold insulation defects. When [...]
