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.

The mold comprises two main parts: the injection mold (A plate) and the ejector mold (B plate), which are also known as moulder and mouldmaker. Plastic resin is introduced into the mold via a sprue or gate in the injection mold. The sprue bushing seals tightly against the nozzle of the injection barrel of the molding machine, allowing molten plastic to flow from the barrel into the mold, known as the cavity. The sprue bushing guides the molten plastic into the cavity impressions through channels on the A and B plates. These channels, called runners, enable the plastic to flow along them. The molten plastic moves through the runner and enters specialized gates, ultimately filling the cavity geometry to create the desired part.
