NU VU Conair Pvt Ltd is 50:50 JV with The Conair Group (Part if IPEG, USA) and NU VU Engineers Ahmedabad, formed in 2007, manufacturing all auxiliaries required for upstream side of moulding and extrusion machines. These include storage silo, vacuum conveying system, dehumidifying drying system, gravimetric blending system, loss in weight system ( EPC),mould temperature controllers, chillers, crystallizer and granulators. We have state of the art manufacturing facility for manufacturing high quality equipment. The critical components are imported from Conair Group and rests are manufactured in India as per Conair design.
TRUEWEIGH® Loss in Weight System or also known as Extrusion Process control (EPC) System, which monitor and automatically control extruder throughput result in huge saving of polymer for the processor. The first question that comes to everyone is what this system does.
The next question that pops up is why is this system needed in our plant.
Next you will be interested to know how it works.
The Loss in weight hopper which is mounted on load cell are installed on extruder throat, the load cell precisely measure material feeding in to extruder, and pass the information to PLC based Controller. The control system then varies the extruder RPM to maintain desired kgs/hr going in to extruder irrespective process variation and condition. The control system also synchronizes the haul off device.
This system is available in different models and configuration to suits every processor needs. Up to 12 Extruder and one Haul off on a single co-extrusion line can be monitored and controlled. Our team will study each and every application and design system which will benefit the processor. The system is used with single screw flood –fed extruder in Mono or Co-extrusion line for
Typical process flow for Multilayer film line
The TRUEWEIGH® can be used to control following
The benefits include,
The following benefits can be realized in multilayer line,
