2.1 Computer simulation technology Computer simulation technology is currently mainly based on the numerical simulation of the flow field of die casting, the temperature field of the die casting mold/die casting, and the numerical simulation of the stress field of the die casting die/die casting. Vigorously develop computer simulation technology, perform filling and solidification analysis, and form an expert system on this basis to achieve the ideal cavity filling state and mold thermal equilibrium state, which can predict casting defects such as porosity and shrinkage of die castings and residual stress and deformation The situation and the life of the mold ensure the reliability of the design quality to obtain high-quality castings and high productivity. The die casting process is a complex flow, heat and mass transfer process. At present,most of the numerical simulation of the die-casting filling process starts from the material cake or the runner. The slow injection process of ...

At present,  die-casting aluminum parts  used in the industry mainly include the following series: A1-Si, Al-Mg, Al -Si-Cu. Al-Si-Mg, etc.  Die-cast aluminum alloy has high specific strength, corrosion resistance, and good casting performance, processing performance, and reproducibility, as well as excellent electrical and thermal conductivity, and is widely used in the automotive, aerospace and electrical industry industries.  With the development of the automobile and other industries, the output of aluminum alloy die castings increases at a rate of nearly 13% per year, and its output accounts for more than 75% of the output of all die castings. And aluminum alloy die-casting parts are developing towards high strength and high quality, which will definitely promote the further development of aluminum alloy die-casting technology. 1 Development and application of die-casting aluminum alloy Traditional Le casting aluminum alloy parts are not suitable for heat tr...

The manhole cover is our common existence, and it can be seen everywhere when walking outside.  Due to different functions of the manhole cover, "electricity", "dirty" and "rain" are written on it and various symbols are drawn on it. But no matter how many use the manhole cover has, the shape of the manhole cover is basically a circle.  Have you ever wondered why the manhole cover has to be round? The problem of the manhole cover being round can be traced back to France in the 13th century... When France was building ancient Paris, it used around discus as the manhole cover for the sewer. Later, the Roman Empire used French sewer technology to build a Roman city. Later, major cities around the world successively adopted Roman sewer technology. As a result, the round manhole cover seemed to become a conventional thing.  In fact, the circular manhole cover has many advantages~! 1 Not easy to fall Round, each radius from the center to the edge has ...
