Coupling screws - Import export

Worm screws, gear wheels, slide rails and other technical mouldings are today made of engineering plastics such as POM (polyoxymethylene), PA (polyamide) or PE (polyethylene). These materials with different property profiles (negative high water absorption with PA, poorer wear behaviour with PE) are supplied as sheets or rods. The required moulded parts are then produced by mechanical processing (turning, milling etc.) in a more or less complex manner. Effective injection moulding is only worthwhile for large quantities together with small component sizes, otherwise the high tool costs cannot be amortized. secutexTechno is characterised by high hardness (70° Shore D) and rigidity over a wide temperature range. It retains its high toughness down to 30 °C, has a high abrasion resistance and a low coefficient of friction. The intrinsic colour is yellow, making it well suited for technical applications. Mechanical processing is simple and comparable with other hard plastics.
