Maintaining Quality in Production

Nowadays, manufacturers are constantly trying to attain the maximum quality possible for their product. The quality is measured by physical characteristics such as hardness, stiffness, tensile strength, flexibility as well as visual appearance which also plays a major role. Waste rubber level during the process also has a high impact on the overall costs of production and this is not often considered by rubber plants. The Pelmar Group has in stock top leading European brands of pre-owned extruders such as Troester, Andouart, NRM and Berstorff. Pelmar’s stock includes cold and hot feed extruders with a wide range of screw diameters, varying from 25 Φ mm through 90 Φ and 120 Φ mm up to 250 Φ mm at different lengths and diameter ratios.
