To improve plasticizing effect, different raw material need different screw structure design.

为提高塑化效果，我们通常会根据不同材料设计不同的螺杆结构。

Screw type螺杆结构分类:

Gradual type, mutation type, wave type, barrier type, double screen type, shunt type, separation type, exhaust type, pin type, mixing type, double-head type, three-head type, multi-head type, pelleting type, etc.

渐变型、突变型、波浪形、屏障型、双屏型、分流型、分离型、排气型、销钉型、混合型、双头型、三头型、多头型、造粒型等
