(Such as dimensional accuracy and surface roughness), reduce the processing margin, and further promote the use of gas, high pressure, pressure and extrusion modeling and other highly mechanized, automated, high-density
Wet sand molding process is the future development of small and medium-sized castings, the main direction of development. The use of nano-technology modified bentonite, or in the use of binder in the bentonite technology to improve the quality of bentonite is to promote the use of wet sand molding workers
The key to the art.

The development of triethylamine cold box method of anti-moisture and anti-cast mold vein technology to save the binder to reduce pollution, reduce casting defects and reduce production costs.

Improve and improve the vertical type boxless injection molding machine and air impact molding machine performance, control system functions, while the modeling line auxiliary machine should be generalized, serialized principles of development, improve the matching level.

Seize the development of personalized shape, practical airflow - compaction molding machine suitable for shape complex modeling or multi-species mass production.

Improve the quality, technical content, technical level and supporting capacity of the sand processing equipment, fill the technical gaps including the old sand cooling device and the bucket elevator suitable for conveying the old sand as soon as possible, and strive to improve the sand processing system
The design level.
