Effective strand drying during pelletizing to be presented at Interplastica

The Maag brands “maag pump systems”, “automatik pelletizing systems” and “maag filtration systems” will be presenting a SG-C die head, a strand pelletizer as well as a gear pump extrex GP at Interplastica in hall FO, stand B049. Also on display is the screen changer HSC 50.

Die heads or pelletizing units are used in strand pelletizing systems for extrusion of strand profiles. SG-C series die heads have been specifically developed for applications in masterbatch, compounding and recycling processes. They are used downstream of single and dual screw extruders. Automatik pelletizing systems offer an absolute uniform and homogeneous melt distribution. There is no separation or de-mixing of the components.

Automatiks Hot Air Knife (HAK) was specifically developed for efficient reduction of deposits and fiber residues. It is an optional or retrofitting device mounted to the die head of dry cut strand pelletizing systems which efficiently removes melt residues, outgassing remains, and die drools (such as build up of glass fibers) from both the die holes in the die plate as well as from the extruded strands themselves. With the hot air knife, product contamination can be reliably prevented and disruptions to production minimized.

Extrusion plants need extremely reliable units with high pumping consistency and a configuration to suit each application. The modular design of extrex® gear pumps makes light work of meeting diverse requirements. Due to pioneering gear and bearing technology the extrex® gear pumps achieve a high overall efficiency and minimized shear stress.

Manual screen changers from maag pump systems allow you a cost-effective filtration in extrusion lines. Starting at size 45, the manual screen changers optionally come with transmission gearing. Here, the breaker plate is equipped with patented gearing and a pinion which allows an effortless screen change even in restricted space conditions or high sealing pressures. The manual screen changer guarantees the protection of gear pumps and fine extrusion die gaps from damage and dirt accumulation.
