New Control System Allows Complete Process Integration Including
the Capability to Accommodate Various Voltages of the Heating Elements

High-Technology Corp. has announced its latest generation of screen changer microprocessor based controls that enable complete integration with the extrusion process including remote start/stop and interlocking features for high polymer pressure. For the first time, various voltages for the heating elements can be accommodated and the same supply voltage is used for both the process and control zones.

These controls provide a comprehensive system that supplies continuous feedback on all the screen changer’s operating parameters. Operator friendly indicators display the status of the screen changer system. Operational parameters are easily set via a door mounted display panel. Alarms and indicators immediately alert to a system malfunction and facilitate trouble shooting by pinpointing the source of any failure. Temperature and pressure indicators have digital displays and security codes.

Safety features prevent the possibility of operating the screen changer in an incorrect or unsafe mode, and include protections to prevent the operator  from inputting improper settings or attempting accidental, unintended maneuvers.  Security codes protect against unauthorized users.

Complete automation of the screen changer’s functions enable it to become a fully integrated element in the extrusion process, resulting in months of non-stop operation, with no process disruptions and no operator intervention.

High-Technology Corp. offers fully automatic, continuous screen changers that are used in every segment of plastics processing including: blown film, blow molding, sheet and film extrusion, filaments & fibers, pipe and profile, pelletizing, BIAX (BOPP and BOPS).   HITECH™  melt filters are designed to be used with all families of thermoplastics, including Polyethylene (LDPE, LLDPE and HDPE) Polystyrene (PS, HIPS), Polycarbonate, ABS, Acrylic, Flexible PVC, Nylon (PA 6, PA 66, PA 11) and Polyesters,  as well as a wide range of engineering resins.
