Project title To reduction in Internal Leakage of Tata cub radiator From 0.83% to 0.43% Time period - Oct 10 to Jan 11 Project Selection Date-25 Nov 2010
Data collection Tata Cub radiator Leakage data from Oct-2010 to Dec-2010
Process flow of Radiator Clinching 1 2 Bottom tank side nail clinching Bottom tank Edge nail clinching 4 3 Top tank Edge nail clinching Top tank side nail clinching
Details of Tata cub Radiator Assembly Tata cub Radiator assembly Top Tank Pressure cap Clinching area Core Core Support Drain cock Bottom tank
Defect Description Radiator Leakage area edge clinching Defect
Cause & effect diagram for defect Clinching Leakage Machine Man Is the specified M/C used ? Is operator trained ? Is it due to improper handling M/C Setting parameters Is operator temporary ? Is M/C in good condition ? Is it due to improper Rework ? Radiator Leakage Header plate nail height ? Clinching tool Are Control Plan followed ? Tank flatness ? Tank pusher Method Material Tooling
Root Cause analysis for defect Clinching Leakage Machine Man Radiator Leakage Clinching tool Tank flatness ? Tank pusher Method Material Tooling
Why-why analysis Why-why analysis for caused 1 – Clinching tool
Identified cause & action Cause no. 1 Slot is given at the center of tool. At the time of edge clinching job get shifted & nail not clinch by tool properly. Due to this problem of half clinching, nail cut & job get leak. Action Slot of tool is filled with welding. At the time of clinching resting area of tools get increased & clinching is get properly. Given solution implemented on 25.12.2010
Continued… Action for model :- Tata cub On Edge clinching tool slot is available Slot is filled with welding
Continued… Action taken for model :- Tata cub Nail open OK clinching After filling of slot
Why-why analysis Why-why analysis for cause 2 – Tank pusher
Identified cause & action Cause no. 2 Tank pusher is flat at bottom side due to this uniform pressure not apply on tank. Action Tank pusher is modified for uniform pressure. Given solution implemented on 25.12.2010
Continued… Action taken for model :- Tata cub Tank pusher is flat at bottom Tank pusher is modified for applying uniform pressure on both end of tank Profile added Flat side
Continued… Changeover part modified
Why-why analysis Why-why analysis for cause 3 – Tank Flatness
Continued… Cause no. 3 Tank Flatness Action 1) Cooling fixture is modify by changing toggle size & toggle position. Given solution implemented on 27.12.2010
Continued… Plastic tank Toggle Cooling fixture
Tangible benefits Tata Cub radiator Leakage data for 1 Jan to 15 Jan
Achievement Rejection reduce from 0.83 to 0.42%
Improved knowledge Confidence improved Stage daring improved Internal customer satisfaction In tangible benefits
After completion of our target 0.83% to 0.43% we select next major defect for Reduction in leakage Future plans
