Yeh Der purchased Moldex 3D and Hypermill K-Mold software in 2005 to make molds more efficiently and precisely.

1. Moldex3D

is capable of predicting the filling, packing, and cooling processes of the injection molding and volumetric shrinkage of the plastic materials, which helps to decide the right positions of gates, cycle time and the right plastic material, etc.

Moldex is the abbreviation of "Mold Expert". This software is capable of simulating the filling, packing, and cooling processes of the injection molding and the warping of the plastic parts ejection. In addition, it helps to precisely predict distribution variables (including the flow, temperature, pressure, shear stress, and volumetric shrinkage of the plastic materials) at the end of every process before opening the mold. The time-history curves of variables such as sprue pressure variation and clamping force, the possible locations of welding lines and air traps are also predictable with the Moldex application. In addition, Moldex can be used for evaluating the efficiency of the cooling system and estimating the shrinkage and warpage issues for the product beforehand.

Modex3D is the latest developed three-dimensional analysis software. It contains not only the functions as described above, but also utilizes pioneering FVM technology. What this new FVM technology can provide are the capability of analyzing the real conditions that can't be solved by STL and Midplane analysis, speedy and accurate calculation, extra humanistic operating interface and latest 3-D technology that is able to display every analysis result realistically. All these functions are designed to facilitate learning and operating. At present, Moldex3D has already released Flow/Pack/Cool/Warp/Fiber modules in both shell and solid series.
