Teklas (Gebze, Turkey) has recently started to produce fluid-carrying tubes for automobiles in high volumes using water-assisted injection molding technology (WIT). The parts use a special grade of Ultramid A3HG6 WIT polyamide (PA) developed for the process by BASF (Ludwigshafen, Germany).

This glass fiber reinforced PA 66 grade enables good inside and outside surfaces to be formed as well as offering the required high chemical resistance. A new series of tubes that Teklas is currently developing for almost all large European automobile manufacturers provide individual conveying of cooling water, air and oil in the engine compartment.

Turkish processor makes application advances with water-assisted injection molding.

For post-molding processing of the tubes, Teklas, which operates a production facility in Kardzhali, Bulgaria, relies on a high level of automation: The numerous finishing steps that are needed in the course of manufacturing the tubes, such as cutting and sanding, and incorporation of metal rings and elastomer (TPE) seals, are performed by robots. This contributes to a low reject rate. Teklas is currently very successful with this innovative WIT process and the wide range of manufacturing options, and is supplying and developing a variety of different tubes. Plans already call for expanding capacity.-[email protected]
