In our production process we basically melt a mixture of granules (plastic, filler, masterbach, colour…) and transform them into profiles. We call this process "extrusion". By means of a suction system (comparable to a vacuum cleaner), the granules will be put into the hopper.
From here they will be further melted on a single or a double screw extruder that is heated up to 200°C (the temperature can change in function of the type of compound). The extruder transports, grinds and melts the granules at the same time. At the end of the barrel the melted mass will be pushed into the mould.
After this the viscous mass is pulled through a calibration system (cooling and under vacuum) by a caterpillar. Finally, the profile will be cut to the demanded length, packed and putted into metallic containers.
