The line will consist of two Tandem extruders, which guarantee high productions with densities up to 80 kg/m³. UNION’s Tandem solution facilitates the achievement of the extrusion quality in particularly short times, even for a critical material such as PET where temperatures reach even 280°C.
The rheological study of the product has allowed the company to produce a circular die with which, although varying the thickness and density, it is not necessary to change the die’s male.
A new extruder cooling system keeps the temperatures at the set value, which is very important when using expanding gases to achieve a perfect cell formation. A very important detail is also a cooling calibrator with a particular surface, studied by UNION, that avoids any friction and makes the sheet surface of appearance and brilliance at the top of all foam extruded products.
