Conical Twin Screw Extruders
The NCMT series of conical twin screw extruders offered by Neoplast is the fifth generation of conical twin screw extruders developed under technical collaboration with M/s. Cincinnati extrusions, Austria, who have an experience of designing more than 6000 PVC processing lines.
Our customers, benefit from this experience by way of enormous processing latitude, extreme life & the most favourable price/performance ratio.
NCMT series extruders from Neoplast are designed to ensure a higher return on your investment, i.e. outstanding cost-effectiveness, higher output & excellent product quality.
Neoplast offers conical twin screw extruders for RPVC pipes, CPVC pipes, SWR pipes, engineering profiles, furniture profiles, building sections, etc.
Integral Components
Cimitherm (Internal screw core thermoregulation)
- This system is based on the heat pipe principle.
- Heat is transferred back from the hot screw tip to the cold feed zone, resulting in considerable energy saving.
- Cimitherm is a self-regulating system that adjusts to changing heat transfer requirements & does not require any adjustments.

| Venting Unit
The venting port on the barrel is coupled with a specially designed efficient venting pump for effective removal of air and gases generated during the plastification process.
|
 |
Top-Performance Control Panel
It is provided with complete sequencing logic for interface with upstream and downstream equipments used in extrusion line.
Dual display PID temperature controllers for extruder and die zones are also provided.
To guarantee optimal ease of operation, all set-point and actual values along the extrusion line can be processed, visualized and evaluated at a central location.

 |
Metering Unit
Metering unit facilitates accurate adjustment of the screw filling factor and plasticizing capacity.
It is ideal for materials with the possibility of density variations & particularly suitable for processing regrind and pellets. |
 |
Barrel Heating Cooling System
Specially designed barrel heating cooling elements (air power cooling) and precise locations of thermocouples ensure accurate temperature control. The large surface area of cooling elements result into the highest efficiency and lowest maintenance.

 |
Screw and Barrel Life
A novel wear resistance coating technique, ensures exceptional long life of screw & barrel, the heart of the extruder.
The wearing layer achieved with this technique is denser, more compact and less brittle than conventional coatings applied with customary methods.
We guarantee extreme abrasion resistance.
|
 |
Threaded Barrel
Due to unique manufacturing techniques, barrels are with absolutely accurate conical bores.
The barrel is made from nitro- alloy steel with hardness of 50 Hrc, which in turn undergoes two-stage gas nitriding to achieve final hardness of 67 Hrc.
