STEM PROCESS FLOW

Contract confirmation→Confirm the technical requirements (drawings)→Production plan (check the number / material)→Material→Confirm blank drawings (forging) directly without forging heat treatment→The same furnace test stick mark→Heat treatment (clear technical requirements）→Hardness test（HB/HRC）→Mechanical properties testing (validation)→Blank sorting (mark card)→Process card into the blank straightening (coarse grinding）→The progress of products Merchandiser→Blank rough machining→CNC machine finishing (inspection)→Car side / milling machine processing (inspection)→Drilling / tapping, deburring, machining center (inspection)→Thread cold press forming (gauge inspection)→Fine grinding→Surface pressure light processing→Polishing processing→Before leaving the factory inspection→Label→Packing (export / domestic)
