Mother-baby extrusion system is designed for special materials which can not process on one stage extruder, the first stage is a twin screw extruder, and the second stage is a single screw extruder.
- PVC compounding for cable / hose / pipe fitting
- HFFR cable compounding/XLPE for cable
- High-concentration carbon black Masterbatch (MB)
- others
When you should use a double-stage extruder?
If your material needs special dispersion but not over shear like the cable material (PVC, XLPE, HFFR, etc). The primary twin screw extruder provides the mixing and dispersing, the second single screw extruder is for pelletizing.
