EXHIBITION PREVIEW | NPE 2018
Right: Coperion’s STS 35Mc11 will be shown optimised for colour masterbatch production
and ESD packaging applications. The additions to the company’s T-TEC lines cover high temperature resistance and permanent electrically dissipative performance. The high-temperature masterbatches and compounds are intended for use in high performance amorphous and semi-crystalline engineering polymers requiring continuous operating tempera- tures above 150o
C and multiple heat histories exceeding 350o C. Complementing the
Colloids range of PACE engineering polymer masterbatches, the new high temperature master- batch grades have been formulated using specially selected pigments and carrier systems based on PPS, PPSU, PPA and PEEK. They are available in standard blue, red, green, brown, grey or black, as well as in customer bespoke colours. The permanently electrically conductive ESD additions to the E-TEC family includes 11 products offering surface resistivities from 1 x 109 103
to less than
Ohms square (according to ASTM D257 and IEC61340-2-3). The are said to be formulated to provide good mechanical and processing properties. �

Conair will unveil the latest update to its Wave Conveying technology and will launch a new Indus- try 4.0-based materials management, monitoring and visualisation technology marketed under the SmartServices name. The company claims the Wave Conveying system – which is a development of the company’s R-Pro technology – is the first vacuum-powered materials handling system to provide precise control of both material speed and flow. It says this means it can move materials over longer distances, at higher throughputs and at almost any speed without the risk of dust or “angel hair” creation. The system uses Conair’s FLX-128 Plus conveying control, Wave Conveying vacuum pump with variable-frequency
drive and Wave Conveying PHOTO: COPERION 46
control valve in combination with stand- ard receivers and pipework. This allows material to be drawn in pulses, each separated by an air gap, and moved in gentle rolling waves rather than suspend- ed in high speed air, the company claims. SmartServices is said to combine equip-

ment monitoring and visualisation with cloud- based storage and analytics. Conair says it is designed to provide new levels of process, performance and quality optimisation, along with predictive diagnostics and maintenance features to maximum equipment uptime. The system uses wireless machine adaptors (WMAs) installed in the controller of each item of equipment that collect and transmit data to the cloud-based SmartServices database, where it is presented to the system user in a clear dashboard format allowing performance, status and alarms to be monitored. �

Coperion and Coperion K-Tron will show their latest innovations for the compounding industry, including a 35mm STS Mc11 twin screw extruder optimised for masterbatch production, an SP100 pure strand pelletiser, plus a new US-manufac- tured rotary valve and improved twin screw feeder. Providing a specific torque of 11.3 Nm/cm3
and
screw speeds of up to 900 rpm, the STS Mc11 extruder has been optimised for colour master- batch production and includes a number of new features that improve handling and ease of cleaning. These include a new base frame with integrated water manifold and wiring connections and a re-engineered extruder cover design that allow easy access to the process section while reducing dust contamination and providing a smoother surface for easier cleaning. Barrel heater shells on the new model are fitted with insulation plates to minimise surface tempera- tures on the processing section while the feed barrel opening is equipped with a removable sleeve, which supports simple cleaning and quicker colour change-over. A tray has also been added to the vent port to collect any vent flow and the die head has been redesigned for faster cleaning between production runs. The STS 35 Mc11
at the show will be fitted with a
Coperion K-Tron K2-MV-T35 volumetric twin screw feeder, which is designed to provide economic and
