The precision casting forming process can not only shorten the development cycle of new weapons, but also reduce manufacturing costs and improve the flexibility of weapons. reliability. After the cruise missile cabin is made of aluminum alloy precision casting, the cost of the missile body has been reduced by 30%, and the man-hours per missile has been reduced from 8000 hours to 5500 hours, the reliability has been increased, and the weight has been reduced. The precision thermal process has a short production cycle, low cost, good parts performance, and high product reliability. The advantages such as nearly no margin for blank making are highly valued by countries all over the world.

The technology is derived from silica sol casting, with a set of advanced casting equipment and material composition detection equipment, the casting size is accurate, the surface finish is good, there is no need to reduce the mechanical processing, and the material and processing costs are saved. Cooling during the process is a very important process.

1. When the alloy steel castings are air-cooled, they should be dispersed in a dry place;

2. After the workpiece is quenched, it should be tempered in time, the time interval should not exceed 4h, the alloy steel castings used in the workpiece contain low carbon (the mass fraction of carbon), and the shape of the workpiece is simple, no more than 16h;

3. It can be cleaned after low temperature to room temperature. Low temperature treatment or tempering;
