Maguire and Italy’s Syncro that began in 2016 with Maguire taking an investment position with Syncro. “The partnership draws on Maguire’s experience
in materials handling and blending systems and Syncro‘s extensive range of control systems for extrusion applications,” says Frank Kavanagh, Maguire Vice-President of sales and marketing. “It enables us to provide customers with turnkey control systems for virtually any type of extrusion operation.” Initially the WXB blender is available in three

Movacolor’s MCHybrid 30R blender combines gravimetric and volumetric technology
to be picked from many storage devices and to be addressed to many destinations,” says Lorenzo
Zamberlan, Product Marketing Manager at Piovan. “Other current issues include the control of humidity and crystallinity after pelletising and the increasing use of WPC materials – PP- or PE-wood compounds.“ Zamberlan says the company is addressing the
first of those trends through development of its Easylink+ automatic coupling station. “We have also introduced a new Material Tracking System as part of the Winfactory 4.0 supervising system to keep materials flow under control in production and to optimise consumption and stock levels,“ he says. Maguire Products has launched the WXB, a

weigh extrusion blender that provides extrusion control based on batch precision and metering accuracy and can be interfaced with a supervisory system that controls the total production line. The company says the WXB incorporates a gain-in- weight (GIW) weigh bin and a loss-in-weight (LIW) mix chamber in one machine, together with a Maguire 4088 controller. While the GIW function precisely weighs batch ingredients as they are dosed sequentially into the weigh bin, the LIW mix chamber makes accurate metering of the blend into the processing machine possible. The 4088 controller is designed for communication with other systems in an Industry 4.0 setting. It enables the WXB blender to interface with the Maguire + Syncro supervisory system, which provides control of all segments of a production line from a single touch-screen HMI control. The Maguire + Syncro brand is the product of a partnership between US-based

models: WXB 100 for throughputs of 50-100 kg/h (100-220 lb/h); WXB 200 for 100-200 kg/hr (220-440 lb/h); and WXB 400 for 200-400 kg/h (440-880 lb/h). The blenders can be configured for up to twelve ingredients, each with a separate dispenser. The WXB mix chamber is easily re- moved for quick cleanout and all loading system options available from Maguire are integrated into the controller. Well known for its Flexwall line of volumetric
and gravimetric feeding systems, one of the more recent additions to the Brabender Technologie product line is its fibre feeder. Designed for feeding natural fibres, wood fibres, shredded films and long carbon fibres, the unit uses a special screw, steep walled hopper and fibre optimised hopper agitator that ensures good feeding of the material into the screw. The company says the units‘ CM controller allows accurate setting of the feed screw to agitator speed ratio, which it explains is the secret to effective fibre feeding. Koch-Technik has developed the Kem-Touch
direct colouring device as a cost-effective solution for dosing masterbatch or additives directly in the material input of a processing machine. The company says the device offers a simple design that provides precise volumetric dosing via a new stepper motor with an epicyclic gear that provides improved precision, starting and stopping behaviour, as well as 60% lower energy con- sumption. The control system is
integrated into the Kem-Touch casing and includes several programs to provide precise dosing, including support to dose in accordance with an extruder rotation pulse. Control is carried out from the
unit’s touchscreen via a clearly structured menu. Dosed quantities can be set continuously in percent-
