There are many kinds of casting defects, and the reasons for the defects are very complicated. It is not only related to the casting process, but also related to a series of factors such as the properties of the casting alloy, the melting of the alloy, and the performance of the molding material. Therefore, when analyzing the causes of casting defects, it is necessary to proceed from the specific situation, conduct a comprehensive analysis according to the characteristics, location, process and sand used of the defects, and then take corresponding technical measures to prevent and eliminate defects.
The die-casting process is a process of organically combining and using the three die-casting production elements of die-casting alloy, die-casting mold and die-casting machine. There are many factors that affect the filling and forming of molten metal during the pressure prayer, among which the injection force, injection speed, filling time and die temperature are the main ones.
Powder metallurgy is a process technology for preparing a mixture of metal powder and non-metal powder as a raw material, after forming and sintering, to manufacture metal materials, composite materials and various types of products. Powder metallurgy products industry only refers to powder metallurgy products, including powder metallurgy parts, oil-impregnated bearings and metal injection molding products. Today we will take a closer look at this process.
Injection molding mold processing plant should pay attention to the following matters when installing the standard mold frame:
