挤出机在挤出过程中，出料不稳定,物料断断续续是比较常见的问题,之所以挤不出物料，其主要的原因和机筒螺杆的温度控制不合理及熔融物料的流速达不到要求等相关，减小螺杆冷却水的流量，冷却水的温度提高;
1、分流板和过滤网的堵塞使物料运动阻力过大,物料在螺槽中的轴向运动速度人大降低,也会造成不出料的现象2、挤出机的机筒、螺杆的温度控制不合理,温度过高或过低都不行。机筒温度过高，与机简接触的物料发生熔融，容易造成物料过热分解,如果螺杆温度过低则会造成物料与机筒打滑而不出料。
针对以上问题，其解决的办法主要是降低机筒温度;减小螺杆冷却水的流量,冷却水的温度提高;定期清理和更换分流板和过滤网。
格出机的格塑成型及调整,对温度控制的精确件、稳定件及可提作性要求越来越高。一方方面要求挤出机厂家对其挤出机设计要科学合理，另外采用精密先进的温控系统也是必须的。世研机械采用优质温控系统，能够使温度精确控制在+0.2°℃，为良好的挤出成型提供了先决条件。
世研机械提醒，稳定的温度控制使挤出机所挤出的物料的物理特性更好，其是对线性高密度聚Z烯的物料效果更加明显。
