We can predict the filling and shrinkage behavior of molten resin injected into the mold of an injection molding machine. By understanding factors such as moldability, the location of weld lines, required clamping force, and tendencies for warping and deformation in advance, we can apply these insights to mold designs that improve productivity and product quality. With over 5,000 successful cases, we aim to further improve prediction accuracy based on these accumulated experiences.
