After Zhou Jingming and Lao Huang put on their hard hats, they came to the workshop site under the leadership of Hu Yibing.

The advantages of using this method are obvious, that is, the internal stress of the finished product is low, and the warping deformation is also very small, so that the mechanical properties of the friction plate are also very stable.

Because the batch of production is not much, Hu Yibing's best consideration is naturally the cost problem.

The production workshop is not big, at a glance, you can see the head, there are a total of four small hydraulic presses in the whole workshop, which are used to control the pressure required for molding, because the equipment is old, every time the hydraulic press works, it will make a lot of noise, and near each hydraulic press, there are molds for molding.

"Director Hu, the hydraulic press equipment you have here should be obsolete equipment that has been eliminated by others. Because the noise was too loud, Zhou Jingming had to raise his voice.

"We can't help it, little comrade! The scale is here, if the equipment is used so well, how can we still make a profit? So many brothers are waiting to open their mouths to eat!" Hu Yibing said with a wry smile.

However, Hu Yibing was very surprised that Zhou Jingming could see the problem of the hydraulic press at a glance, it was not the first time that SAIC had come here, and no one could see the clues in the first few times.

"Didn't the factory director think about expanding production?" asked Zhou Jingming curiously.

"The annual output of Shencheng brand cars is only seven or eight thousand, less than 10,000 units, I want to expand the scale of production, but I can't find a market! ”

Zhou Jingming knew in his heart that he had forgotten about the issue of sales, and the production capacity of Shencheng brand cars was too low.

The situation here is just a microcosm of SAIC's many suppliers, and if the supply chain problem is not solved, the localization level of Santana models in the later stage cannot be improved in any way!

Zhou Jingming thinks that from this time, there should be a conscious integration of relevant supplier resources, so that when Santana is officially introduced, it will not take three years (that is, in 1988) to achieve a localization rate of 27%, and it will not be until 1991 to really bid farewell to the CKD assembly model and realize localized production.

"It doesn't necessarily have to produce friction plates, since the output of a single product can not be improved, you can consider diversifying production, clutch, not only friction plates, pressure plates, driven plates, or compression springs, Hu factory director can go to production, if Hu factory director is bold enough, the production of the entire clutch assembly, it is not impossible, as long as the quality is passed, the main engine factory is still very willing to purchase these components. ”

Zhou Jingming just said casually that diversified production is not uncommon in the future, even e-commerce companies can build cars, what else can not be invested in cross-fields?

It's just that the speaker is unintentional, the listener is intentional, Zhou Jingming's words are like opening the door to a new world, which makes Hu Yibing's eyes light up, and he feels that he may not be able to give it a try!

But for now, it is still necessary to overcome the difficulty of burning the friction plate.

After a turn in the workshop, Zhou Jingming did not find any problems, the process of molding is very simple, only feeding, mold closing, exhaust, curing, demoulding and mold cleaning, and these process engineering needs not many control elements, it stands to reason that there should be no problems.

However, since there is no problem with the design, the friction plate is burned in such a short time, and the only way to find it is to look for the reason from the process.

Could it be that it is a problem with the material?

Thinking of this, Zhou Jingming stopped in front of a pile of raw materials, "Director Hu, which method is used in the molding process here?"

"The fiber molding method, and then the raw materials used are mainly synthetic resins, asbestos-based materials and other reinforcing materials and auxiliary materials. Hu Yibing explained.

"Please rest assured, although we are a small business, the equipment is relatively old, but in terms of materials, there is absolutely no cutting corners, are in accordance with the provisions of the procurement and allocation. Hu Yibing could also guess what Zhou Jingming was thinking, and hurriedly assured.

Zhou Jingming was silent, although he didn't know much about materials, but in the eighties, counterfeit and shoddy products were not common, and it could even be said that there were none, he was just guessing.

After looking around again, Zhou Jingming didn't make any new discoveries, and the three of them walked out of the workshop.

"How is it, has Comrade Xiao Zhou found out what the reason is?" asked Hu Yibing.

Zhou Jingming shook his head, "Not yet." ”

"Otherwise, it's almost noon, let's eat first, and then continue after eating, do you think it's okay?"

Lao Huang looked at the sun above his head, and then nodded, "That's fine, then it's troublesome to Director Hu." ”

"Yes, let's go and rest for a while, and I'll arrange for cooking. ”

The two of them came to the office again, Lao Huang sat down and took off his hard hat, "Is there really nothing to find?"

Zhou Jingming also took off his hard hat, wiped the sweat on his forehead, and frowned, "There is really no progress for the time being, let's take a look in the afternoon." ”

"It's okay, I don't care about the past day or two anyway. ”

After lunch, under Hu Yibing's arrangement, he found two rooms for Lao Huang and Zhou Jingming to rest.

The workers in the workshop were smoking and chatting around at the moment, Zhou Jingming looked at it, and then stopped in front of a hydraulic press, except for this, he really couldn't think of anything else that could be a problem.

"Master, can you ask if the distribution valve of this hydraulic press usually leaks?" After watching for a long time, Zhou Jingming finally saw some clues, and couldn't help asking.

"Leakage, you say? It's an old problem! All the hydraulic presses here have this situation, but the pressure required for molding can still be satisfied. A master lying next to him said with a smoke ring.

"All leaks?"

Zhou Jingming's eyes lit up, and then he quickly walked to the other hydraulic presses to take a look, and sure enough, there was water-based emulsion flowing out near the distribution valve!

"The hydraulic press works according to Pascal's law, and if there is a leak in the working medium, will the working pressure not be affected?"

Zhou Jingming looked at the hydraulic oil on his hand and seemed to have found the problem.
