The die head of the plastic granulator has three types, including electric gear die head, hydraulic die head and automatic slag filter. The function of the machine head is to transform the rotating plastic melt into a parallel linear motion so that the plastic melt is introduced into the mold sleeve evenly and smoothly, and the plastic is given the necessary pressure for molding.

分流套通常被放置以确保机器头部的塑料流动路径合理,并消除塑料积聚的死角。此外,通常还提供一个分级环,以消除塑料挤出过程中的压力波动。模具校准和调整装置也安装在机器头部,以调整和校正核心与模具套的同心度。
