Werner Koch Maschinentechnik GmbH said its KE-M metering equipment puts color concentrates directly into the feeding area of the screw of an injection press or extruder, via a free inlet.
It is mounted directly on an adapter flange, usually in combination with a conveyor for new material.
Three control units are available, based on time, speed or a percent of the shot weight.
Koch, which makes mixing, dosing, conveying and drying equipment, will show the KE-D at K 2001 in Dusseldorf, Germany, in Hall 10, Booth A-37. The company is based in Pforzheim, Germany
