Phrase:
People make mistakes, That's the very reason why they put the rubbers on the ends of the pencils.
It's Thursday and sunny today, i woke up about 4:30 this morning, and then i went to the office directly, i need to attend a Skype meeting with STC team and global quality and techinical team to discuss the local customer complaints, such as click noise, clip broken etc.
Klim said all the noise issues should be analyzed synthetically, including rotor, caliper, lubrication etc.
I asked Rain to check the dimensions of D1322 randomly, after confirm all the dimensions meet the specification, so i sent the measurement result to Klim for review.
the Wangda said they also cann't solve this issue, and suggested us to repeat the testing more than 20 days, and then confire the data whether can get right? this is a very bad news.
i will answer Wallace's some questions at tonight's meeting:
•Why is itcracking? Making the adjustment is aninterim corrective action but does not cover the root cause. Is the settings wrong or have they beenworking, if so what changed?
Most of the crack at the center of the friction block, we use the same temperature, cycle time for all the part numbers, but some of the part number didn’t apply to the current parameters, another reason we cann’t fixed workstation for one part number, so I think it is very difficult to find out the root cause, we only record the special part number and when we
produce these part number our technician will use the newest parameters to adjust.
Like the crack issue, if the temperatureswere working what changed? Is this your rainy season? Does the mix have more moisture?
Yes, for the reply also as the crack issue, The moist month from June to September normally, the moisture of the mix about 1.1-1.8
What you describe in the actions is thepart is sticking to the punch. Does itstick after cleaning the punch? Do theyclean the punch each cycle? If no thenhow many cycles pass before cleaning the punch with the wire brush?
Our operator clean the mold according to the work instruction, such as the M47 160PCS, but most of the formulas are 80pcs each time, but the operator should adjust the cleaning frequency according to the actual appearance of the pads.
Cups in the wrong location is 46% of theproblem – When will Maintenance have all of the press fixed? Presses that have been corrected have theyhad the problem again, if so how long before failure? Sporadic issues could be the result of thescale itself, capability and improvement may be needed for weighing system.
For the thickness quality issue total 89pcs during the past month, for the wrong location our operator will do the TPM before each shift, so when he find the location of the cup is wrong, they will tell this problem to maintenance guy for help, but the location will change when the chain run continually during the production, currently we hadn’t found the change rule
