The wireless die head (no wire die head, no wire mesh filter) has rotary type, push-pull type. Zhejiang Lenon has longer production time, more mature technology and more customers.
The wire-free screen changer (no-net die head) is a kind of coarse filter. It is currently mainly used for the front-stage filtration of waste plastic recycling granulators, and is widely used in the recycling and granulation of various waste plastics. It does have many advantages, as follows:
1. No need to change the wire mesh, which reduces the labor cost when changing the mesh and reduces the labor intensity of workers;
2. No need to replace the wire mesh, reducing the consumption of traditional filter wire mesh;
3. The continuity of granulation is ensured, and the output of granulation is improved;
4. A certain melt pressure is established in the head part to enhance the plasticizing effect of the material.
