Extrusion lines, tools and pipe heads HIGH Tech Extrusion, consisting of the companies Theysohn, Technoplast, Topf and Extruder-Komponenten Salzgitter, is an “all-in-one” provider, which has developed a unique series of extrusion lines, tools and pipe heads. For more than ten years High Tech Extrusion has engaged intensely with this topic and works on future trends for coextrusion. This version is cost-effective and extremely space saving. This piggy back solution can be also mounted on non- Theysohn extruders, of course. Recently High Tech Extrusion was technically challenged by British customers as they were interested in modifying their old extrusion lines into co-extrusion lines. High Tech Extrusion accomplished this by mounting a conical extruder CON 50 “piggyback” on the existing extruder from a competitor. These customers were highly satisfied with the result. The requested output was achieved and

due to the unique “piggyback” system, shortage of space at the plant was no longer an obstacle. The guaranteed output with the CON 50 conical extruder as coextruder is for PVC window profiles 125kg/h and for rigid-PVC profiles 150kg/h. To increase output, High Tech Extrusion is now working on a solution for the conical extruder CON 63 as coextruder. In this case a successful mounting is dependent on the size of the main extruder. Pillar version for profile tools of all kind – for this type the extruders are positioned next to each other and the coextruder is mounted on a pillar. High Tech Extrusion offers solutions for the single screw coextruder CO.32 as well as the conical extruders CON 40 and 50, and is working on a construction for the CON 63. The CO.32 single-screw extruder can be used for profile- and pipe extrusion with rigid-PVC, soft-PVC, PA, PMMA and thermoplastic elastomers (TPE).

Now the group offers three different and advanced solutions for the industry. Coextrusion is very important for the extrusion market as costs for material can be reduced dramatically. The core of profiles or of pipes is produced from recycled or other cost-effective material. For example, material costs can be reduced by 30 per cent with the production of 3-layer pipes. “Piggy back solution” for profile coextrusion – The conical extruder (CON 40 or 50) or the CO.32 single screw coextruder is mounted on the main extruder. With the newly developed clamp system for the piggy back solution the adjustment of the coextruder is possible in all directions (up, down, side and angular), therefore a perfect position of the coextruder can be guaranteed.
