In-line regranulation

The new version of the Recotrim system, developed by Macchi – located in Venegono Inferiore VA, Italy - for in-line regranulation of blown film trims, improves the thermoregulation system of the extrusion unit, melt pressure, speed of blades and alarms.
In addition to standard operations, the new version can automatically perform Syncro and Auto-Blades functions. The former is intended for setting granule shape and size proportionally to the extrusion speed, which is especially useful during line setting and start-up; the latter, by means of extrusion pressure control, makes it possible to obtain granules with uniform shape, which is important when trim feed is not consistent.
