AB  - This study investigates the effect of injection molding parameters on the shrinkage of five recyclable polymers—HDPE, PC, TPV, ABS, and PP—using Moldex3D simulation software. A complex geometry modeled on an iPhone cell cover was analyzed, with mold temperature (40°C and 80°C) and melt temperature (200°C and 280°C) as the varying parameters, employing a full factorial design of experiments (DOE). Results showed that melt temperature had a more significant impact on shrinkage compared to mold temperature. ABS exhibited the least shrinkage (1.96 mm), making it ideal for applications requiring dimensional accuracy, while TPV showed the highest shrinkage (15.98 mm). HDPE demonstrated moderate shrinkage (7.68–13.79 mm), and PC showed balanced shrinkage (3.54–8.92 mm), while PP performed better at lower mold temperatures (4.18–7.30 mm). The study reveals that shrinkage generally increases with higher melt and mold temperatures, and highlights the importance of precise parameter optimization, especially for complex geometries. These findings provide actionable insights for optimizing process parameters in injection molding, contributing to the better adoption of recyclable materials in high-precision manufacturing. Future work could explore additional parameters, such as injection pressure and cooling time, and investigate the recyclability of these materials post-molding.
