The co extrusion consists in adding a layer or a coloured strip to the main wall. The layer can be inside or outside of the pipe.This process work only with the vacuum system.MATERIALS : PP - PE - PVC - PA…
Application: this production is mainly to produce the HDPE/PP pipe from 300mm to 3500mm(ID). This kind of pipe is made from HDPE or PP with hot winding technology. It is of high ring stiffness, low weight and easy jointing. It can be used for drainage and water supply. It is of electrical fusion welding socket and spigot, this is the most of reliable joint compare other drainage and sewerage pipe jointing system.
Pipe extrusion line: The material is metered to the extruder, plasticized and extruded as an intermediate product which is cooled and calibrated by downstream line components. Components for wall thickness measurement, cutting to length and stacking can be integrated in the production line.
PVC pipe extrusion line:The KraussMaffei Berstorff manufactures complete conventional and automated extrusion lines of extruders, ranging from pipe molds, downstream and automation components, to all peripheral equipment. Some of these equipments include drinking water pipes, irrigation pipes, drainage pipes, and coextrusion pipes with different combinations of materials such as PVC foam core pipes.
Masfen Extrusion lines is able to work many thermoplastic materials as a PE,PP,PPRC,HDPE,PVC,PA66 etc. With user friendly touch screen panel easily used by operators.with energy saver equipment and quick start mechanism of machine will be very profitable for investors.
The X:GRAN series from NGR Recycling Machines are manufactured with modular designs. The screen changer and the pelletizer can be varied depending on the application of the extruder. These devices are capable of accepting materials, even in big bales without pre-treatment or additional handling.
