Battenfeld GmbH of Meinerzhagen, Germany, is offering the Lubrimelt plasticizing unit on its TM and HM injection presses, to ensure reliable processing of self-lubricating plastics.
The unit is equipped with several grooves, distributed around the cylinder in the feeding zone, to ensure controlled transportation of material between the granulate and cylinder wall, even in the case of a low-friction coeffient, the firm said.
Also, the machine builds up high pressure in the feeding zone, so metering adjustments are possible in the melting zone even when wall slippage occurs because of insufficient shear speeds. The length-to-diameter ratio ensures the screw will melt materials completely.
Battenfeld of America Inc. is based in West Warwick, R.I.
