JWELL barrels are specifically designed for CJWS series. Standard barrels can be produced both as solid and liner insert, as well as having a modular structure that provides high flexibility to its users.With its optimized barrel channel structure, it provides an excellent heat transfer with cooling medium and electrical heating at the process section. Each zone has a separate heating/cooling system and provides users flexible working opportunity.
As an option, another barrel structure produced by JWELL the clamshell barrel system. It
provides maximum and easy access to the process section by opening the split barrels horizontally &
thanks to its modular structure that enables the screw and barrels to be changed very quickly. Thus, the system ensures easy cleaning of the barrel and screw segments at the end of each production cycle. Easy assembly and disassembly, easy cleaning, no needing for extra equipment for replacing and repairing are some of the advantages of JWELL innovative barrels. One of the main distinguishing quality features of JWELL twin screw extruders is the automatic control of electric heating and liquid cooling systems with zone temperature control. Therefore, each zone has a separate heating and cooling control.
In addition, different types of barrels can be produced according to customer demands and our production capabilities.
The design of the twin-screw extruder provides an advantage over other plastic processes. Full flexibility gives the process engineer the ability to configure the extruder to optimize the process and produce the best properties attainable.
Viewing the twin-screw extruder as a series of unit operations, the process engineer has the opportunity to address:
Solids conveying;
Melting of polymers;
Customizable mixing of additives into the melt;
Liquid injection;
Downstream addition of additives;
Venting (atmospheric and vacuum);
Pumping;
Heat Transfer;
Chemical reaction, in the case of reactive extrusion.
