The sprue-bushing  MOLD DESIGN FUNDAMENTAL CALCULATION · 1 Machine Clamping Force (Fc). In this video, we explore how  7) Consider the running distance (runner and the cavity) by the number of gates and their location: this directly affects the injection pressure and runner's  A runner is a channel cut into the mold that allows plastic material to flow from the nozzle to the cavity. The proper  Mold dimensions → To determine platen size and mold stroke; Number of cavities → To calculate required shot volume and clamping force; Cold  D=W1/2×L1/4/3. Maintain equal flow path from sprue to each cavity. This calculation ensures  This can be calculated by measuring the length and width of the mold and multiplying them together. 7 D is the runner diameter (mm); W is the weight of the molded part (g); L is the runner length (mm). @educationwood 88 likes 5.
