  • High-tech flat sheet film
    the manufacture of flat sheet film involves mixing three or more components with a single or twin extruder The melt exits the extrusion head flat film extrusion dye as a thin flat sheet Multilayer extrusion heads are used when different raw materials are transformed into composite layer film during the co extrusion process The extrudate is fed immediately to the casting or cooling roller where it is processed into a flat film with the desired properties The cooling roll rotates faster stretching the extrudate making it thinner and wider An airbrush ensures contact with the cooling roll while the neck is held to preset limits through various electrodes and air nozzles If the surface must be embossed an embossing roller is used instead of the casting roller to acquire the desired results A cooled silicone roller presses against the embossing roller to produce the desired design effect After casting the film is measured for thickness The extrusion head and speed of the extruder melt pump or various rollers can be adjusted automatically or manually if necessary For sheets needing higher tear strength or greater transparency the sheets can be stretched to orientate the molecular structure to one direction machine direction or to two directions bi axle This step is carried out either simultaneously or consecutively During orientation of the machine direction the cooled and stabilised film is heated to optimal temperature and stretched by passing through a series of closely located rollers The stretching effect can be precisely varied by adjusting the speed settings When necessary additional rollers can be mounted prior to discharge For orientation in the cross direction a process is used in which the film is pre heated and stretched in the pinch and tempered in various applications Because several sheets must be pre treated for later

  • Monopigment and additive masterbatches
    POM PC additive wax inorganic and or organic pigments Typical throughputs 250 500 kg h Process description The term masterbatch describes plastic granules which contain high concentrates of colour pigments or additives Masterbatch contains a higher percentage of pigment or additive than the finished product Masterbatch is made up of raw polymers which are then dyed or otherwise processed Polymer based masterbatch in granulate form guarantees a higher degree of process security than pastes powder or liquid substances and drastically produces less pollution or contamination One explanation for the term masterbatch comes from the general term used in the production of rubber Historically only a master craftsman was allowed to manufacture and mix the high concentrated batches hence masterbatch There are basically three groups of masterbatch colour masterbatch monopigment or tailor made which is used to dye plastic goods additive masterbatch which determines specific properties of the end products i e UV stabilisers flame protection anti static or anti block and finally combination masterbatch with both dyes and additives Masterbatch is generally concentrated in a pigment and or additive ratio of 40 10 With help of an extruder normally twin screw polymers pigments and or additives are blended into a homogenous mixture This is achieved using a pre mix or split feed process During the pre mix process a pre mixture of polymer pigment additive and eventually dispersion means are brought together in the main inlet area This pre mix is placed into mixers in batches The melting wetting homogenisation and dispersing processes takes place in the extruder A volumetric doser is sufficient when using the pre mix process because the recipe elements are exactly weighed and matched in a separate mixer During the spit feed process a twin screw extruder is outfitted with a main and side inlet on
