Latest Patents

One of Okawa's latest patents is a track link production method that aims to provide markedly improved wear life while maintaining good cost performance. This innovative method includes a heat treatment process that involves quenching and low-temperature tempering treatment applied to the entire link material after hot forging. The design ensures that desired machining is applied to the link material before the heat treatment process, followed by sequential tempering and finish machining for parts requiring high dimensional accuracy. Another significant invention is a bucket tooth designed to prevent a bolt from loosening during operation. This bucket tooth generates a resilient return force after attachment, achieved by causing a warp through resilient deformation, resulting in a concave face on the bucket lip side.
