At present, despite the current global economic downturn, precision stainless steel may have a certain impact on domestic mold exports, but my country's investment casting mold industry has a good momentum of development, and export mold casting molds account for more than 30% of GDP.

It is reported that under the guidance of the macro policy, from the perspective of the development of the alloy steel mold industry and the domestic and international market capacity, the domestic and international large-scale precision and complex investment molds and die-casting mold markets are still broad.

At present, my country's investment casting mold manufacturing technology continues to improve, and the process continues to improve. It has attracted the cooperation of world automobile giants such as North American General Motors and American Chrysler. In addition, the mold price advantage of my country's automotive oil shell die-casting molds exported to Europe is great. In the future, the export of domestic investment molds will not be limited to Europe. North America, Japan, South Korea and other places will also open up more markets, and exports will continue to rise.

What formula should be used for surface cleaning of alloy castings? How to make a choice? Ordinary cleaning of stainless steel castings, including ordinary cleaning, ultrasonic cleaning, degreasing cleaning and vacuum cleaning, etc. They have their own characteristics, and the cleaning agent formula used:

Which formulas can be used to clean the surface of stainless steel castings? How to make a choice?

Ordinary cleaning of stainless steel castings, including ordinary cleaning, ultrasonic cleaning, degreasing cleaning and vacuum cleaning, etc. They have their own strengths, and the formulas of the cleaning fluids used are different. The general cleaning agents are solvent-based (petroleum cleaning agents and organic solvent cleaning agents). In the heat treatment of stainless steel castings, the following methods are mainly used:

①Metal cleaning agent, mostly used for cleaning before stainless steel casting and chemical heat treatment;

②3%-10% cleaning fluid or sodium hydrogen radon, the temperature is controlled at 80-100℃, it is mostly used for precision stainless steel castings such as oil removal, salt removal, rust removal, and rust removal.
