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.
Planetary Cutting saw
A: Planetary saw blades cutting for pipe diameter up to 800mm;
B: Rotary cutting make sure smooth and clean;
C: Cutting is PLC controlled;
D: Saw dust powerful sucking device
E: Special hard alloy saw blade is employed to cut heavy caliber thick wall pipes.
