Terrible Day It was a terrible day yesterday.I am an supplier quality enginer in China.I am in charge of Al wheel.Yesterday Al wheel had a problem about the dimension of central hole.The central hole's dimension is too large that the wheel cap had a step with the wheel cental hole.It is a quality problem and It caused our assembly line stopped produing ten minutes.It is an serious inccident in our company.I tried my best to solve this problem but it ended badly.I did not feel well.In the few days,I have to learn lessons about this inccident.I wish I will make good deals with similar problems in the future.
