PVC Compounding Units

Malik Engineers manufacture MEWR-PVC Series Extrusion Units for manufacturing PVC granular compound from dry blend. Full machine comprises one single screw extruder complete with heaters, motor, screw & barrel set, multi-hole die-plate, one water cooling tank, pelletiser and a seperate control cabinet for complete machine. The screw and barrel are duly nitrided for long life and screw geometry is designed for PVC compounding application, to impart proper mixing to the compound and controlled shear to prevent overheating of melt. The extruder continously pumps strands in the cooling tank where the strands are cooled down and fed to pelletiser which is fitted with hardened cutting bladed, to produce granular PVC compound. An L/D ratio of 24:1 is provided as standard to impart sufficient mixing to produce homogenous compound. A separate model is available which is provided with single vent port & suitable vacuum pump, to remove any volatiles and moisture/air from the compound to produce pellets free from pin holes and air entrapped. The temperature control panel is provided with electronic solid-state controllers with suitable sensors to maintain the set temperature accurately and additionally, air blowers are mounted beneath the barrel to force cool the same in event the temperature overshoots limits. This is essential on account of extremely heat sensitive nature of PVC material. The machine is offered in screw sizes from 50mm to 100mm having corresponding output capacities of 30 kgs and 150 kgs/hour.
