Homepage of Kaimei copper elongation

 

 

　I am performing melting and casting of the brass now. I talk about dissolution and casting, the improvement this time.

 

　Each work includes perception and an art, and there are many technical places not to be able to express by the words.

 

I dissolve a scrap of the brass which I purchased in a smelting furnace, and I pour it into a mold, and the casting in particular makes a billet.

 

There are two processes before becoming the billet.

 

　It is combination to become the first start. A brass stick and the raw materials have many materials and are characteristic each.

 

The combination technology studies while doing melting and casting what kind of raw materials you go well when you put it together.

 

Unevenness appears and worsens quality to use the same raw materials because an ingredient level varies according to quantity of combination.

 

Can judge impurities-rich the thing to acquire experience for many years on seeing an epidermal color to some extent, but current I for lack of experience,

 

I sharpen the surface and judge it using cancer-style analysis.

 

　And finally, it melts with the thing which I combined and confirms an ingredient level again.

 

After all the control of speed and the ingredient of the combination work is difficult because there is less experience,

 

I become very afraid whether you do not send a defective article to the next process.

 

Because ingredients are different even if I purchase the raw materials of the same materials every time, usage is very difficult.

 

I repeat experience while getting perception and an art little by little and learn a technique to teach it to younger students as a future problem.

 

　You perform a monthly improvement activity by the Kaimei copper elongation and must be improved variously as it is the production spot.

 

I dissolve the casting for high heat of 1,000 degrees Celsius. The nozzle which is necessary for casting earlier which flowed is set and I operate the nozzle and cast it.

 

Workability right changes by the quality of nozzle. I was in charge of the improvement of the nozzle management place this time.

 

　I intended to make the thing which I imaged in a head, but do not let you strain well for some reason at the start. After all it is inconvenient for an initial article,

 

Because he/she did not use all of the staff either, I was not able to manage it.

 

　And, in the next month, I improved it many times with yoku々tsuki, and at last all the members used it.

 

Using the management stand, I made replacement instruction the rule at the exchange time of the jig.

 

It is easily made of anyone and understands that I send a stable good item to the next process and the customer and repeats improvement.
