Injection moulding had been one of the best choices in plastic manufacturing industry as it manage produced complex-shaped plastic parts in very short cycle times. This article is concerned with the flexural properties of low-density polyethylene (LDPE) reinforced with rice husk (RH) filler specifically for injection moulded parts. In this study, the RH/LDPE composites with different loadings of 5, 10, and 15 wt.% RH were feed into injection moulding machine and the moulded parts were tested using conventional universal testing machine. The results showed that the flexural properties of the RH/LDPE composites were strongly affected by the filler loadings. Furthermore, all the flexural properties of the RH/LDPE composites showed increasing trend as the filler loading increased, up to 15 wt.% of RH loading.
