Screw Conveyor Products
The plasticizing screw can be divided into four zones according to its function:
1. Solid conveying zone
This section is connected with the feeding funnel, and the plastic solid particles are tightly
compressed to form a solid bed, which is subjected to the shearing effect of the melt cylinder,
in addition to gradually increasing the temperature of the plastic, the plastic is transported
forward.
2. Delay of melting
This section is the area from the end of the solid conveying area to the area before the
formation of the melt pool. The viscous force (drag force) accumulates in the forward
screw groove, and the pressure formed at the end of this area is large enough to deform
the solid bed, and the accumulation in the front screw groove gradually forms a melting pool.
