PENGEMBANGAN PROSES MANUFAKTUR BOLT HEX SOCKETUNTUK MENGATASI PERMASALAHAN CACAT PERMUKAAN MELALUI PROSES RE-TEMPERING
In theprocess of makingBoltHexSocketproblemsoftenoccurwherethe biggest flawis thecolor streaks, where the results ofthe surface treatmentprocess(Black oxideprocess) differentcolors(Color Stripe) after thetreatmentprocessalignment(Straightening) whichcauses thevisualpartisnotgood.The existence ofthisdefectis not allowedbecause itcancause thesurfaceis notresistant torust. Tocope withthese conditionsand increaseproduction targets, it is necessary todiscussimprovementstoovercomethesedefects, as well astoimprove theproductivity ofmanufacturingprocessesHexSocketBolt.Parameters which are required checking Tempering is the process parameters that include process temperature (°C) and the length of time the process Tempering (s) and the process of repair surface defects that occur after the alignment process (Straightening) due to the surface corrosion resistance , the addition of the Re-tempering tempering or process 2 times.
This study intends to answer the question that arises due to the addition of the heat treatment process (Re-Tempering) Hex Socket Bolt on parts to repair defective parts after surface treatment process alignment, namely how the influence of process temperature (°C), the length of time the process Tempering (s)and the addition of the Re-Tempering the surface defect, and Structure Mechanical Properties of Materials at Bolt Hex Socket.Output to be achieved in this study was to determine the effect of process temperature (°C), the length of time the process Tempering (s) and the addition of the Re-Tempering the surface defect, and Structure Mechanical Properties of Materials at Bolt Hex Socket .
