Injection moulding parameters and performance of rice husk-high density polyethylene composite

A column end cap part was produced from a two stages process. The first stage was the compounding of rice husk and HDPE into pellet size and the second stage was moulding it into a product. Four sizes of rice husk were used at various compositions. The size ranged from 500 Âµm and below (coded as A,...
