Some applications require high reliability. For instance in the manufacture of flexible oil drilling that are produced in ​​continuous mode and are made in one piece, without possibility of interruption. The dosing of stearate is essential to provide lubrication in the extruder and ensure quality consistency. MCPI offers micro feeders for stearate powder, operating successfully despite the difficulty of this very hygroscopic powder. The design of the dispenser has been studied to allow the implantation on the plastic granules feeder, an accurate dose of 7 grams is provided every 12 secondes.
