What is the role of mold flow analysis for die casting molds

Nowadays, die-casting molds are used in many places. When die-casting molds are in progress, mold flow analysis is required, so how should we operate?

The deformation of the part can be predicted. To predict the absolute value of deformation through deformation analysis, it is necessary to be very careful when using it. Deformation predictions can be used to compare gate locations, wall thickness changes or design changes.

You can check and correct the problematic mold prototype. The best way to detect problems in the mold is to use the mold prototype to do a ‘short shot’. Mold flow analysis can determine which changes will be effective, faster and less expensive than mold repair.

You can know the efficiency of the cooling circuit. Adding cooling analysis to deformation analysis can increase accuracy. Because the cooling water circuit is in the mold, it is difficult to modify it once it is completed, so this type of analysis is very useful before opening the mold.

Repair the welding line problem. Mold flow analysis can predict where the weld line will occur and help how to move it to a place that is not prone to problems. It can also provide clues that affect the quality of the weld line, such as the temperature at the front end of the melt flow and the pressure required to fill the weld line. However, mold flow analysis cannot predict the strength and visibility of weld lines. `
