Conical Twin Screw Extruder

A: Counter Rotating Conical twin screw machined on CNC make thread milling machines by simulation software for better performance.

B: Conical twin screw extruder is specially designed for high calcium loading.

C: Compact & reliable gear box

D: Synchronized drives of the extruder, feeder, and haul-off enable the ease of operation. It is designed for high output at low screw speed and less power consumption.

E: Bi-metallic screw & barrel can be provided for two -three times more lifespan than nitrided screw and barrel.

Die Head

A: Die head is made of high carbon content forgedalloy steel for better life and performance.
B: It has resonable flow channel design and special treatment on the surface;
C: Special flow channel design ensures the equal distribution of PVC in the mould;
D: Melt temperature and pressure remain even.

Spraying Bath

A: Intensive cooling of the pipe with the help of number of spraying nozzles;

B: Axial adjustment of thank on slide rails with locking arrangement;

C: Self cleaning type spray nozzle with wide opening for intensive cooling of the pipe;

D: Acrylic transparent cover for easy inspection.

Pneumatic Haul Off

A; Twin and multi-track system;

B: Track can be adjusted for different sizes of pipe ranging between 20mm and 800mm;

C: Hall-off is synchronized with extruder with the help of AC frequency variable drive;

D: Gap between two tracks and pressure is adjusted pneumatically;

E: V-Groove rubber pads mounted on chain with proper tensioning to prevent ovality for large even for large diameter and think wall pipes.
