Business review, Major challenge and issues Nov, 2011 Metaldyne Korea
Supply Quality Main reasons
Assembly PPM [PPM] [PPM] Rejected % of Theta BSM Rejected % of R- BSM • To improve the NVH problem, DIC(Local gear supplier) changed the material of brush tool from wire to ceramic coating on May 18th. • Got a big NVH failure for R BSM in Sep due to cleanliness issue of test oil
Customer Quality [PPM] [PPM] Main reasons
Quality 5star Improvement plan and Target • Customer ppm was getting worse for the changing rating criteria of HMMA from the 2nd half of 2010
Quality Timing chain cover Improvement (Tau Engine) • HM - FEMA was common used with VI in order to prevent oil leakage.(May 2010) • GDI TCC was common used with MPI to get better porosity issue and leakage issue (May 2011) Nut loosening is occurring at China and HMC salvage (Theta Engine) • The root cause has not been found yet. • MKL is considering to implement bolt type instead of current nut type. Engine Oil pressure issue (Theta Engine) • Oil pressure High and Low problem was occurred due to FCV stuck at the FCV bore. • FCV stuck could not be detected 100% at MKL EOL test. • MKL is trying to find inspection method to detect this problem 100% at MKL process Input shaft stuck (Theta Engine) • MKL improved rough machining tool of input bore in order to minimize the burr. • MKL will implement de-burring process to eliminate burr at oil hole on Dec 1st. • MKL will change oil filter of EOL tester to prevent BSM damage by foreign material in the test oil. 6
