Chapter 57 A story caused by an ordinary production change application

Automobile OEMs have very high requirements for the production stability of parts.

The confirmation of various CP values ​​and CPK values ​​is closely related to these.

For auto parts suppliers, any changes in materials, component sources, equipment changes, production site changes, etc. need to be reported in advance and can only be implemented after being recognized.

These contents will be emphasized in the "change point management" requirements of each OEM.

As a supplier of nut plates, Nanshan Auto Parts Factory needs to replace stamping equipment to produce nut plates. This matter naturally needs to be reported.

However, since they are the second-tier suppliers of Spring City Volkswagen and Modu Volkswagen, their reporting target is the Spring City Stamping Factory.

Afterwards, Spring City Stamping Factory will report to the OEM to obtain approval for the change.

"Old Wang, for such a simple process change application, we have to fly to Yangcheng. Isn't it necessary?"

"Anyway, those presses are all used to produce nut plates. It doesn't matter which one you change."

Liu Darui has opinions about Nanshan Auto Parts Factory.

At the beginning, he was scolded a lot for the nut plate mold.

Therefore, he would not go on a business trip to Nanshan if he could.

But this time, it was Wang Le who took out General Manager Dong Chun's hat and forced him to go on a business trip with him.

"Bu Liu, Nanshan Auto Parts Factory has several presses that produce nut plates. If there is a change between these presses, I will naturally not ask you to make a special trip."

There is obviously a reason why Wang Le came so actively to confirm on site this time.

You know, before this business trip, Zhang Fugui and Cai Rong from Nanshan went over to report to him.

"how?"

"Did they buy new equipment again?"

Liu Darui's words were a bit sour.

Nanshan Auto Parts Factory is developing so fast that they are not used to it.

"If we continue to buy presses from Aida or Schuler, then we don't need to make a special trip."

"Just make sure there's no problem with their changed size parameters."

When Wang Le said this, Liu Darui became a little curious.

"Is it possible that they purchased equipment from a third manufacturer?"

“Then the equipment on site will not be of IWC brand, it will be available from any company?”

"This is very difficult to manage. Are they not afraid of problems?"

As the director of the technical department of Spring City Stamping, Liu Darui often needs to follow the procurement to the second-tier suppliers to do some audit work.

IWC equipment is obviously something they don't want to see.

"It's difficult to manage. That's their own problem."

"Anyway, the nut plate is produced using the PRG process. As long as the equipment is suitable, changing it will not have much impact."

"But this time, they directly used equipment produced by themselves, and they kept selling to us, trying to persuade us to purchase his press."

When Wang Le said this, Liu Darui understood why he needed to be dragged to the scene in person this time.

However, he is not optimistic about Nanshan's self-produced equipment at all.

“When it comes to PRG technology, Nanshan is one of the best in China.”

"I admit this!"

"But designing and producing PRG presses is completely different from PRG molds. I have never seen any stamping factory in the industry produce their own presses."

"They are messing around like this. Don't damage the mold by then, which will affect our supply."

Liu Darui's focus is not at all on Nanshan's self-produced presses.

He is just worried about whether the molds supplied to him will be damaged.

If the mold is broken, it will take time to make it again or modify it.

Supply issues may arise if you are not careful.

Especially during this period, Spring City Automobile Group and Toyota Motor established a joint venture, and the entire Spring City Automobile Group was learning Toyota's lean management production model.

In order to reduce costs to the greatest extent, Chuncheng Stamping Factory does not keep too much nut plate inventory.

When the time comes, the mold breaks down and the inventory is used up, causing Modu Volkswagen and Spring City Volkswagen to cease production...

Thinking of that scene, Liu Darui felt extremely stressed.

"It shouldn't be..."

Hearing what Liu Darui said, Wang Le also felt a little guilty, "Since Nanshan Auto Parts Factory dares to invite us to come over for an on-site inspection, it means that the quality of the presses they produce should be pretty good."

"At least judging from the equipment parameters they provided and the size parameters of the nut plate after the change, they are not weaker than before the change."

In this way, the two of them have been chatting about Nanshan since they got on the plane.

When they arrived at the Nanshan Auto Parts Factory, they naturally ignored any reports and came directly to the site to see the condition of the equipment.

"Punching 1 times in 25 minute?"

"I remember that the Aida press used to press 1 times per minute, right?"

Liu Darui held a stopwatch in his hand and held the watch himself to confirm the production rhythm.

For stamping factories, if the quality is satisfied, they definitely want the stamping speed to be as fast as possible.

But this is closely related to the situation of equipment, molds and parts.

The faster the stamping speed, the higher the requirements for equipment and molds, and the parts are also required to be simpler.

Nowadays, the parts have not changed, the mold has not changed, but the stamping speed has increased.

Although it only increased three times, it is still a very scary figure.

"Bu Liu, your memory is really good."

"It seems that you know the status of every part."

"You are right. Our previous production cycle of nut plates was indeed about 1 times per minute."

"However, the press we developed ourselves has made some improvements to the crank linkage mechanism and motor, which can improve the production cycle while ensuring parts quality and equipment safety."

Cai Rong was full of confidence and introduced Liu Darui with a smile.

To be honest, Cai Rong did not believe that our own equipment center can produce 600 tons of PRG equipment, and its various parameters completely surpass the existing equipment of Aida and Schuler.

But facts speak louder than words.

"Did you really produce this equipment yourself?"

Wang Le circled the press several times, constantly comparing it with the press in Aida next to him.

During this period, since Chuncheng Stamping Factory was reviewing the introduction of specialized PRG stamping equipment, Wang Le also studied this type of press.

Ordinary people want to fool him, but it's not that easy.

"Wang Bu, from the design to the assembly of this equipment, everything is completed by our Nanshan equipment center."

"Judging from the current confirmed situation, the parameters in all aspects are comprehensively better than Aida and Schuler."

"But our cost is half that of Schuler, and about [-]% cheaper than Aida's press."

“The most important thing is that after purchasing our press, you don’t have to worry about any after-sales issues.”

At this time, it was naturally Zhang Fugui's turn to appear.

As the head of the purchasing and sales department, he will not only need to consider the sales of parts and components in the future, he will also take charge of the sales of equipment.
