At the facilities in Spain, KÖMMERLING uses about 25 tons of raw materials per day. , each of which can hold up to 150 tons. PVC powder is supplied continuously in tanker trucks from the most prestigious manufacturers. 2. THE MIXING INSTALLATION: In it, stabilizers, lubricating products, modifiers to increase hardness and pigments are added to the PVC, dosing the components and obtaining complete homogenization. Once this has been done, the components are taken from the mixer to the extruders. The entire process is automated, and is visualized and controlled by computer programs. 3. THE EXTRUDER: The extruder is the installation that allows the profile to be manufactured from the raw material mixture. The mixture is introduced through the hopper and collected by the extruder.
The material advances through two screws (double helical shaft extruders) through the cylinder of the machine, where it is heated, plasticized, degassed and compressed under high pressures in the die or nozzle. The KÖMME Belize Mobile Number List RLING group has more than 150 extruders that work without interruption in three daily shifts, distributed in several factories around the world, including Spain. 4. PROFILE: At the exit of the extruder there is the nozzle, called die, which gives the profile the desired shape. This tool is an important piece to achieve the extrusion of a perfect profile and consists of plates that make up the contour and interior of the profile. KÖMMERLING has two highly qualified extrusion tooling factories of its own 5.
CALIBRATION AND COOLING: At the exit of the die, the extruded profile bar, still hot and plastic, is stretched through a vacuum calibrator and cooled by water. In this process, the PVC mass solidifies along the gauge. In it, the profile is given its final measurements. A double caterpillar drive train, whose speed can be precisely adjusted, ensures the regular passage of the profile through the gauge as well as through the entire installation. 6. COEXTRUSION: Multiple extrusion or coextrusion constitutes a special technique that allows profiles to be produced from several contributions of material. This technique can be used for different purposes: producing two-color profiles, co-extruding the joints in the main profiles or beadings, introducing recycled material into unseen parts of the profile, etc. 7.
