AUSTRONIC INSTRUMENTS BLOWMOULDING TECHNOLOGIES INC.
Indumat recycling system for film, tape, monofilaments, bags, etc. A shredder, which preheats the material while cutting it into small pieces, is linked directly to the extruder. Preheating material saves half the horsepower in subsequent extrusion. Coarse filter ahead of the double slide-plate fine filter in the extruder removes large contaminants and thus prolongs life of fine filter. Hot die-face or strand pelletizing completes the process. Outputs to 2500 lb/hr.

Operable with materials such as LDPE, HDPE, PP, PS, ABS and coextruded blends at rates to 500 lb/hr. Scrap can be re-introduced accurately via gravimetric blenders. Other features include air- or water-cooled pelletizing, modular design with small footprint, and low noise level.
Plant scrap repelletizing systems for postindustrial scrap recovers costly roll scrap, cut-outs and other waste and reduces size of scrap to manageable inventory.
