Abstract

Injection molding is an efficient manufacturing method for mass-producing plastic components, including syringe barrels used in medical applications. The barrel must be manufactured with high precision and safety standards. Injection molding simulation is needed to evaluate material distribution and identify potential product defects before production. This study aims to design a mold and simulate the injection molding process for a 12-cavity syringe barrel by optimizing the runner system. The molten plastic flow was analyzed using flow analysis software. Two runner layout variations were tested in a three-plate mold construction. Simulation results showed that layout 1 provided better performance in terms of shorter cycle time and lower material waste, making it the preferred design.
