Homepage of Kaimei copper elongation

 

　When it achieved an aim that growth came to be felt me.

 

I entered Kaimei copper elongation, and there was it in the copper elongation section, but I moved in the aluminum pushing out section and was only a thing and inexperienced work to learn newly at the start.

 

I found an aim for oneself in that and was going to be accomplished.

 

This aim was the reduction of the rate having poor improvement of the quality, the improvement of the horyu mari rate. The reason was management philosophy of the Kaimei copper elongation.

 

　There are A6063S, A6063SS, materials including A6005CSS in the aluminum section, and there is a thing varying in purity of aluminum each,

 

In addition, as materials to use by various shapes including an angle shape, the channel shape change,

 

I was not able to distinguish until I was used.

 

Because these come to be distinguished and came to know defectiveness to occur, to be able to send a thing of good quality,

 

I became able to lose a delinquent caused by work.

 

　Therefore it took the data to have gone and performed an improvement activity based on 5S and QC story.

 

It is reduction of the bad rate by a cutting process, the stretcher process to have gone this time.

 

I divided the bad shape that was easy to appear every process into the products before the heat-treatment process from past data again.

 

The main bad contents at the time of the product correction work of the stretcher are twisted, and a curve, a dent occur.

 

I was able to reduce it a little to lose these by changing work contents depending on the situation finely.

 

　In addition, I was able to reduce the wound to be caused at the time of the transportation to a lower process by being careful.

 

The thing that a length difference and the section of the product are not beautiful becomes bad by the cutting process.

 

As not only I changed the how to cut, but also product hardness after the heat-treatment changed, I was improved by a product shape by performing cutting after the heat-treatment.

 

The defectiveness rate has begun to fall in this way when the knowledge for instructions and the product every process increased.

 

At result, defectiveness rate 7.0% of the previous year, I am achieving it with 5.4% for 6.0% of aims now this year.

 

I perform inspection well and want to make a better product in future from now on.
