PVC is a heat-sensitive plastic, and it needs to reach a certain plasticization effect during processing. During the extrusion process, not only the heating, but also the screw thread will give PVC its own frictional  heat, the thread depth above the screw and the screw diameter exsists a specific ratio as well as the compression ratio in order to achieve the effect of plasticization.

PVC Screw For Injection Moulding Machine

Features:

The characteristics of the PVC screw are that in the three sections, the feeding section and the homogenization length are short, and the compression section is very long, exceeding 50%. This is because the PVC is decomposed if it is rapidly compressed, so the compression section is long.

In terms of compression ratio, the temperature sensitivity of PVC makes the compression ratio the smallest among the screws, generally between 1.6 and 2.2, the soft PVC can be upper limit, and the rigid PVC is as small as possible.

The aspect ratio of the PVC screw is also close to the lower limit. Between 18~~22.
