Omipa’s extruders, with their dosing systems and innovative screw profiles, have been designed and manufactured to guarantee the best use of plastic materials. Most of all, they are in a position to produce all the typologies of today’s high technology sheet and foil with the utmost flexibility.
Extruder feeding is accomplished through a volumetric dosing system (or, upon request, through an integrated gravimetric system), assuring rapid change of the dosing percentages and of the material types, combined with easy and rapid cleaning.
The particular extruder screw design, with its innovative helical profile, is a perfect example of Omipa’s knowhow to optimise the production of different thermoplastic materials.
The whole integrated system, from the dosing unit to the extruder, with or without venting, gear-box, motor, filter changer and polymer feed pump, all controlled by an efficient thermoregulation system, always ensures homogeneous and constant mixing and plasticization, with the highest versatility.
Furthermore, with the same objective of responding to concrete production needs, Omipa has developed a series of coextrusion groups, with rapid change of the configuration, in order to process the different materials to be coextruded, on the basis of the number of layers and specific flexibility requirements.
- plate-type coextrusion groups (up to 3 layers)
Used for materials that have similar characteristics or for fixed configuration coextrusion.
- multi-layer coextrusion groups (up to 9 layers)
Used whenever it is necessary to vary frequently the percentage ratio between the layers, whenever flexibility of use with replacement of the selector is required or for coextrusion of materials with very different characteristics.
- multi-layer dies
