Stress is very common in our life and work. I believe that everyone is familiar with it. Corrosion can be seen everywhere, but when the two are superimposed together, the accidents brought about are destructive and irreparable. ...
Sticking is the high-pressure and high-speed repeated impact of the filling metal liquid, which causes a chemical reaction between the surface of the mold steel and the casting alloy, and a chemical reaction layer is formed on the surface of the mold, which leads to the phenomenon of sticking of the ...
Servo motors are divided into two categories: DC and AC servo motors. The main feature is that there is no rotation when the signal voltage is zero, and the speed decreases at a uniform speed with the increase of torque. The motor is an electronic product that uses the principle of electromagnetic, ...
In the high-pressure die-casting industry, traditional mold release agents are used in the process of use. Due to external pollution and other primitives, they usually cause microbial contamination of the mold release agent diluent during use, resulting in clogging of the filter screen and failure o ...
The production process of secondary aluminum alloy can be divided into three stages: pretreatment, smelting (including refining), and ingot casting. The smelting process is to add scrap aluminum into the smelting furnace and heat it to melt into a liquid state. After slagging, temperature measuremen ...
The wall thickness of the regulating piece and sealing piece of high-temperature alloy castings is changed from 1.1mm to 0.8mm, which leads to faster solidification of the castings. The original casting process cannot effectively fill and feed the edges of the castings, resulting in insufficient cas ...
When changing the molding conditions, the combination of temperature, pressure, and time should be prepared in advance, and the results can be known early by proceeding in order. First of all, after the time has become very long, it is easy to know every small change in pressure. It should be noted ...
When the foundation of earthquake zone and tundra zone changes, pipelines laid in the zone may buckle and break. Therefore, improving the buckling resistance of line pipes is very important to ensure pipeline safety. Traditional pipeline design uses the method of increasing the wall thickness of the ...
Because stainless steel casting cools and solidifies faster in metal molds than in sand molds, and the metal molds have no tolerance. Therefore, during metal mold casting, the casting stress generated in the castings is greater than that in sand castings. ...
In actual production, the choice of die-casting machine is mainly based on the type of die-casting alloy, the contour size and weight of the casting to determine the use of hot-chamber or cold-chamber die-casting machines. ...
Excessive temperature rise of hydraulic oil can cause thermal deformation of the machine. Moving parts with different coefficients of thermal expansion in hydraulic components will become stuck due to their smaller fit gaps, causing malfunctions, affecting the transmission accuracy of the hydraulic ...
