Leaders in continuous melt filtration since 1969

High-Technology Corp. has been a leader in the field of continuous automatic screen changers since 1969. HITECH™ screen changers are offered in eleven sizes ranging from 1.0" (25 mm) to 8.0" (200 mm). They feature:

  • No hydraulics - extruder head pressure force moves the screen.
  • No hot breaker plates or dirty screen packs to handle.
  • No mechanical seals or moving parts to wear out or replace.

HITECH™ screen changers are UNCONDITIONALLY GUARANTEED for 10 YEARS AGAINST LEAKS! Our machines and our screen changer controls are guaranteed against defects, parts and labor for a year after start-up. 

The simple operating principle of our screen changers allows the screen to move imperceptibly slowly and continuously not to disturb the polymer flow, and the continuous motion of the screen automatically adjusts to correspond to the rate at which the screen is clogging. 

High-Technology Corp. is the world's leading supplier of filter screens for use with belt-type or ribbon-type continuous screen changers.The filter screen used in HITECH™ screen changers is woven from high-tensile strength stainless steel wire, in the Reverse Dutch Twill pattern, and can be used with all screen changers of similar design and can be supplied in non-standard widths and lengths to suit the customer’s needs. We also supply filter screens for all other makes of ribbon-style screen changers. 

HITECH™ screen changers are used in every segment of plastics processing including: blown film, blow molding, sheet/film extrusion, filaments & fibers, pipe and profile, pelletizing, BIAX (BOPP and BOPS). HITECH™  melt filters are designed for use 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) Polyesters, and many engineering resins.
