Injection moulding - Import export

In the injection moulding process TPE pellets are fed into the machine through a hopper and then into a heated barrel. The heat from the barrel turns the material into a liquid resin which is then injected into a closed mould under high pressure. After allowing the molten polymer to cool, the finished part can be removed from the mould. Injection moulding is a high-volume, high tooling cost process, the advanced properties of our TPE compounds deliver short cycle times allowing parts to be produced at a rapid rate. The information below is intended as a general overview, settings may vary depending on the specific grade selected. Please CONTACT US for detailed processing information Settings Equipment Conventional injection moulding machine Compression set At least 2:1. Special screws with short sections and higher compression ratios (3:1 to 4:1) may be good at low screw speeds Shrinkage Between 1.0% and 2.5% depending on the grade, type of application and location of the gate. Moul

metal separator was developed for the examination of plastic granulates, ground material and powders for metallic foreign bodies. It is used in the injection molding and extrusion areas for slow-flowing material columns. Both the detector and the ejection unit have been specially developed for this area of use. This results in top performance data for precision, operating reliability and ease of cleaning. Failsafe storage of all system parameters Digital signal processing for best detection Process- and condition monitoring Standardised system for a wide area of use Robust construction for maximum lifetime Highest precision in long-term operation Fast ejector for minimized material loss Dismantle without tools All components are easily accessible

Dryflex SE is our standard TPE range. It is extremely adaptable and can be used advantageously in many applications. The compounds are easy to process and are optimised for injection moulding. We have developed endless formulations to fulfil different properties and application requirements to optimise the finished component. Grades with improved compression set properties, high temperature resistance or more cost efficient values are an essential part of today’s wide product spectrum.
