Points to note in the production of high-quality precision castings
With the continuous development trend in the field of precision casting production and processing, there are more and more production processes, and precision casting is one of them. In order to ensure good quality, the production process is also very strict.
The processing technology comes from silica sol forging, with a full set of technical equipment and raw material composition checker. The casting specifications are high-precision and the surface smoothness is good, which can avoid the reduction of mechanical processing and manufacturing, and save raw materials and production and processing costs. Refrigeration is a very important whole process in production and processing:
When the alloy steel castings are air-cooled, they should be scattered in a dry place;
The workpiece should be tempered immediately after heat treatment, the interval time is generally not suitable to exceed4h, the carbon content (molar mass of carbon) of the commonly used alloy steel castings of the workpiece is low, and the workpiece looks simple and cannot exceed 16h;
Cleanup, cryogenic violence or tempering can only be carried out after it is cold to the room temperature;
Precision casting before every wax injectionThree products should be carefully checked for flaws and defects. If the font style is damaged, the plug is broken, the aluminum alloy casting abrasive is damaged, etc., it should be reported immediately.
After the wax shooting task is completed that day, turn off the gasoline pump, return the abrasive tools, clean the equipment and the ground neatly with a gray knife, centralize and place dirty and waste wax, and put the aluminum alloy castings in the trash can.
