A 4 Cavity Mould with Hot Runner is a high-efficiency injection moulding system designed to produce four identical parts in one cycle using a hot runner mechanism. Unlike cold runner systems, hot runners maintain the plastic in a molten state throughout the runner system, reducing material waste and cycle time. This setup is ideal for producing PET preforms, closures, and precision components with uniform quality and minimal defects. It ensures better flow balance, faster production, and less post-processing, making it cost-effective for medium to high-volume manufacturing.
