Profiles in endless lengths are being fabricated by the extrusion method. Plastic granules are melted in a screw by rotation and heating, and forced out through a nozzle which has the exact shape the profile must have. After cooling in the cooling forms profiles are cut in the desired lengths.
The relatively low tooling costs and the flexible choice of items length gives the process significant benefits. The items can be made with longitudinal prisms, with the mark on the surface, bent edges or other geometries that would be almost impossible or very expensive to manufacture by other methods. By co-extruding two materials can be combined to achieve a specific product quality.
Our extrusion machines are suitable for extrusion and co-extrusion of profiles with cross-section of 25×120 to 300×25 mm and the item weight range from 50 to 2.000 g/m.
DKI Plast extrudes mostly profiles:
Due to our specialization in products for the lighting industry, we have a wealth of knowledge on development, design and construction of transparent items that place very high demands on the visual quality and control of the reflected light.
