Single screw extruders are available in 45, 60, 80, 100, 120 mm versions.
For each model there are different types based on:
These machines in their standard version are equipped with a universal screw, but this life can also be replaced with a dedicated one according to the different thermoplastic materials: PVC, PE, PS, PP, PMMA, TPE, ABS.
Thanks to the particular design of the screw and cylinder, we can boast an energy saving on the installed power, while guaranteeing the best production performance.
Friul Filiere produces twin screw extruders that can be CONICAL OR PARALLEL, respectively:
CONICAL: extruders, with counter-rotating screws, are specific for the processing of RIGID PVC from dryblend and granule. Conical extruders are especially suitable for the extrusion of high-speed profiles with high back pressures. Thanks to the particular design of the screws and cylinder, we can boast an energy saving on the installed power, while guaranteeing the best production performance. Available in versions with diameter 43, 53, 63 and 83;
PARALLELS are extruders with counter-rotating screws, with high torque and high production capacity, specific for the processing of plasticized or rigid PVC, from dryblend and granule. They are also used for the production of granule compounds. These twin screws are available in 90,110,130 diameter versions. Thanks to the particular design of the screws and cylinder, we can boast an energy saving on the installed power, while guaranteeing the best production performance.
The co-extruders have very compact overall dimensions and can be used with great versatility, satisfying all extrusion and / or co-extrusion needs. Our co-extruders can also be supplied with separate electrical panel and control console.
For particular needs, and in the event that these machines have to be inserted into existing Lines and / or Plants, our Design Team provides for the creation of customized solutions that optimize space and costs. The necessary connection elements such as flanges, conveyors, sleeves and hoses are made with care to ensure the best interface between the existing equipment within the Coextrusion Line.
The co-extruders are available in three different types:
Each can be made in versions 23, 33, 38 and according to the ratio between screw length and diameter in turn in versions 18D, 23D, 25D.
In order to work different materials in the most correct way, we have identified three distinct categories of machines based on slow, fast and special speeds. They can work both with universal screws and with dedicated screws depending on the thermoplastic materials (PVC, PE, PS, PP, PMMA, TPE, ABS). The insertion of pressure and temperature transducers is also foreseen.
For particular applications, each type of co-extruder can be supplied with special bases and with separate pulpit.
