SJW(M) System

Melt pump is installed between the main extruder and the die. The benefits of melt pumps for extrusion operations includes the elimination of surging and other fluctuations, reduction of inconsistent melt temperatures, high pressures at lower product temperatures, compensation for the pumping or mixing capacity of the extruder, possibly reduced start-up times, and reduction of energy required by the extruder

Application：
–Color masterbatch/ Concentrates
–High loading filler masterbatch
–Hot-melt adhesive
–Engineering plastics compounding
–Engineered elastomers

SJW(C) System

The cascade type of Co-Kneader compounding line is consisted of Co-Kneader main machine and another large size single screw extruder. The stock will fall into the second stage single screw extruder after fully dispersed and distributed in Co-Kneader. It will ensure the materials are processed at lower temperature with the stable extruding The whole process is divided into two parts. Co-Kneader is in charge of kneading while the second stage single screw is focusing on extruding The cascade system is very helpful to achieve the better final quality.

Application：
–PVC compounding pelletizing
–Shoe sole compounds
–Wire cable compounds (XLPE, HFFR, Semi-conductive compounds, etc)
–Concentrated color masterbatch
–Rubber, Final-batch rubber, Master batch, Mixed compound
–Elastomers
–Bio-degradable compounds
–Metal injection molding

SJW(T)System

With the special working principle and shorter L/D ratio of XINDA Co-Kneader enjoys wide application in the field of thermoset plastics compounds and powder coating. Thermocouples can be mounted in drilled kneading pins at various different points along the process section to get the direct contact with the melt. The combination of a liquid heating and cooling system and an extremely precise monitoring of the melt

temperature makes Co-Kneader a very successful solution in thermoset plastics compounds and powder coating toner.

Application:
–Thermoset plastics
–Powder coating and toner
–Bakelite molding compounds
–Polymer: epoxy, acrylic, urethane, polyster, etc
