AI Technical Summary
In the existing MIM process, the degreasing and sintering processes cause a sharp drop in the strength of the green blank, making it prone to collapse and warping. Dimensional fluctuations and internal defects are difficult to control during the sintering process, affecting the precision and performance of the parts.
By employing a specific composite binder design, a nanoporous carbon skeleton is generated under a low-oxygen atmosphere. Combined with oscillatory sintering and dynamic micro-area gas pressure control, integrated debinding and sintering are achieved. Mold design is optimized through simulation prediction, and the shrinkage behavior of parts is controlled in real time.
Achieving a balance between high dimensional accuracy, high density, and excellent mechanical properties within the same process cycle significantly improves part yield and overall performance, while reducing subsequent processing requirements.
