Wide range of processes
Internal cooling design
Based on our unique parameters, ADSTEFAN predicts with high accuracy steady-state temperature distribution in molds while factoring in cooling holes. Then by verifying the temperature balance of the mold, it prevents seizing and examines shortening the cycle time.
And by examining the diameter and depth of the cooling holes as well as the temperature and flow rate of the cooling water, it predicts the size and position of shrinkage cavities to create the optimal internal cooling design.

Comparison of final solidification positions
External cooling design
Factoring in the spray route, distance, angle and pressure, the software predicts the temperature distribution of the mold. Spray conditions are then adjusted optimize the temperature balance of the mold, thereby preventing seizing and shortening cycle time. External cooling design
Gate/runner plan
Through analysis of fluidity and solidification, ADSTEFAN predicts problems in the gate and runner design. It then designs the optimal shape for the gate and runner based on a variety of assessment indicators including fill behavior, gate inflow balance, and solidification morphology. Gate/runner design

Injection condition design
The software predicts the behavior of the molten metal in the sleeve and mold based on injection conditions that factor pouring and machine characteristics. Problems such as turbulence in the molten metal and drop in temperature are diagnosed in advance to create optimized condition settings. Injection condition design
ADSTEFAN predicts the amount of gas that remains in the product and designs the exhaust passage. Various ventilation processes—including our own GF method—are compared and assessed to create the optimal exhaust conditions. Exhaust passage design
The software predicts the effects of the pressure pin through analysis of partial pressurization to determine optimal size, timing, and insertion speed of the pressure pin. Partial pressurization design
