Injection Temperature Effects on the Properties of High Density Polyethylene Crates

This study was undertaken to provide more insight on the optimum injection temperature used for production of PE crates, thereby saving time and money, improving part quality. The work included processing trails HDPE crates in an injectionmolding machine at five temperatures ranged from 220 300°C. Both Rheological mechanical characterization conducted order understand effect properties crates. Oven aging also applied (4 weeks) evaluate long-term thermal stability. results revealed that producing a range (260-280 °C) gives best rheological result. lowest drop stability has been observed produced this range.
