Calculating mold slider dimensions involves considering various factors such as the length of the corresponding undercut (H1), the horizontal travel distance of the slide (S), the vertical distance of the guide block in the slide (H), and the angle between the angle pin and the slide (α). The following formulas can be used: H1 ≧ 1.5W (W represents the width of the slide) S = T + 2-3mm (T is the undercut of the finished product) S = H * sinα-δ / cosα (δ is the gap between the angle pin and the slide, generally 0.5MM)
