Abstract
A waste container has an axle assembly comprising an axle with opposing axle end caps adapted to mount the wheels of the waste container. The axle comprises a metal rod encapsulated in plastic. An annular axle groove is formed near the ends of the axle in the encapsulating plastic. The metal rod provides the necessary strength for the axle and the encapsulating plastic protects the rod from corrosion while permitting the formation of the annular axle grooves used for mounting the axle to the wheel. The axle can easily be injection molded, reducing the cost and manufacturing time of prior axles while still providing corrosion protection.
