Experimental results indicated that the performance of Maddock injection screw was better than that of general-purpose injection screw. 结果表明Maddock注塑螺杆的性能比普通三段式螺杆有较大的提高。
It is indicated that perfect mechanical properties and excellent microscopic morphology were gotten after PVC compound materials molded by pineapple injection screw, and the clearance of Maddock injection screw played an important role in PVC plasticizing efficiency. 研究表明:犁钉型注塑螺杆注塑成型PVC制品有利于获得更好的力学性能和微观形态结构,合理的屏障型螺杆剪切棱间隙将有助于PVC物料的塑化。
