Redesign and reprocessing of multi-pin circular electric connectors and rod end bearing.

In this paper, gives a review of the first a multi-pin circular electric connector and the second a rod end bearing. Multi-pin circular electric connector outer body manufacturing by casting material LM24. Multi-pin circular connectors different types of casting techniques, including as gravity casting, high-pressure casting, low-pressure casting, squeeze casting, and vacuum casting, to compare which one is best for manufacturing with a proper finish. Casting defect, porosity was observed and how to minimize the porosity. X-ray technology makes advantage of porosity checking. Second is rod end bearing material EN8 and EN31 steel mechanical property increase by different heat treatments and compare which one is best, after heat treatment check, Hardness and Tensile properties are discussed.
