When will I have a long tassel?

"Don't underestimate me as a scrap material company. Picking junk is a big business now!"

Mao Yaguang led Tang Zifeng and Han Weichang around the workshop, and said proudly:

"In recent years, the domestic steel market has been severely short of supply. Factories cannot buy steel. Steel mills want to produce steel, but they cannot buy raw materials. Domestic iron mines are now producing like crazy, and some steel mills are even importing from abroad. Iron ore is still far from enough. More than half of the steel plants in the country now use scrap steel as raw materials, and buyers from those steel plants are in our company every day, waiting to collect scrap steel from us."

"Seeing how you can make things prosperous even if you collect some rags, it's really embarrassing to think that our huge machine tool factory has no food to eat." Tang Zifeng said with emotion.

Mao Yaguang said: "That can only be blamed on the conservative thinking of the leadership of your factory. For example, if reporter Bao hadn't told me, how would I have known that you could produce metal balers on the first machine? Think about it, just There are more than a dozen prefecture-level cities in our Xiahai Province. Even if some prefecture-level cities are mainly agricultural and do not have so many scrap steel recycling businesses, cities like ours Jinyao, there must be five or six, right? One purchaser 4 baling machines, adding up to more than 20 units. One unit is worth 200,000..."

"Stop, stop, Manager Mao, your price is a bit low, isn't it?" Tang Zifeng quickly interrupted.

Let's just say that thin people have a lot of eyes. This Mao Yaguang looked like he was giving advice to Lin Yiji, so he secretly hid his personal belongings. If Tang Zifeng had been slower and been ignored by Mao Yaguang like this, he might have lowered the price of a baling machine to 200,000.

"I'm just making an analogy." Mao Yaguang was not embarrassed when someone discovered the conspiracy, but continued: "The more than 200,000 yuan, I said it based on the past price. Even the price of pork has increased in the past two years. , it’s okay to increase the price of the equipment to 300,000, we understand.”

"The price you import from abroad seems to be more than 50,000 US dollars, which is equivalent to 500,000 yuan." Tang Zifeng revealed.

"It's imported. Imported equipment will definitely be more expensive." Mao Yaguang said confidently.

Tang Zifeng said: "You should know how expensive foreign exchange indicators are now, right? We sell it to you for 450,000 yuan per unit. You don't lose money and you save on foreign exchange indicators. Isn't it great?"

"But if we are willing to spend 450,000 yuan to buy it from China, why should we ask you to make a machine?" Mao Yaguang retorted, "Puji and Luoji are both professional manufacturers of baling machines. Why don't I contact them?"

Tang Zifeng had done his homework beforehand and knew that the Puji and Luoji that Mao Yaguang mentioned were old machine tool companies specializing in scrap steel processing machinery and had a high share of the domestic market. The products of these companies are all mature products and have high user recognition, which is far from being comparable to that of Linyi.

If Linyiji wants to grab business from these companies, it must either engage in price wars and attract customers with low prices, or it must introduce new products and come up with some innovations that can impress customers.

Before departure, Tang Zifeng specifically discussed this issue with Qin Zhongnian. Qin Zhongnian also proposed some innovative ideas, but these ideas still need Mao Yaguang's approval to be useful. After listening to Mao Yaguang's words, Tang Zifeng smiled slightly and said: "Manager Mao, you are on to the point. Since both Puji and Luoji can provide balers, why do you want to go abroad to introduce them?"

"The quality of the imported equipment is reliable," Mao Yaguang said. "We originally had two balers, and they broke down every three days. Each time, it was not a major problem. At first, we asked the manufacturer to come over and repair it. Later, we learned the ropes ourselves. You can repair it yourself. But it breaks down too many times. Once it breaks down, your work will be wasted for at least half a day. Who can bear it?"

"What's the main problem?" Han Weichang asked from the side. This is a technical issue, and Tang Zifeng is definitely not working.

Mao Yaguang led them to a baling machine and said: "Look, this is the baling machine we bought from Puji in the past. It has been used for five years. The situation was good in the first two years, and the following three Every year, it breaks down twice a month on average. The main problem is the circuit. There are more than a dozen relays and hundreds of electrical contacts on this machine. Due to reasons such as poor contact of the contacts, it will cause shutdown. In fact, Contact faults like this are very easy to repair, but finding the fault point is a troublesome task. You need to take a multimeter to test point by point, which is very annoying."

"We can solve this kind of problem!" Han Weichang said.

"How do you solve it?" Mao Yaguang asked.

Han Weichang said: "There are many more relays on our machine tools than on this baler, and there are thousands of electrical contacts. Earlier, our machine tools also had the problem you mentioned, that is, the contacts are easily oxidized, resulting in contact Bad. Later, we introduced technology from RB and used PLC to replace relays, and these problems were solved at once."

"That's right, that's right, what I want is that C you mentioned. Why, can you come up with it in one machine?" Mao Yaguang asked.

"PLC, also called programmable controller. Now among those doing this in China, our Linyi machine is the most professional." Han Weichang boasted casually.

PLC technology originated in the United States in the late 1960s, entered the practical stage in the mid-1970s, and was widely used in the 1980s. Our country carried out corresponding research in the early 1970s. In 1982, a domestic PLC was successfully developed and promoted in a small area.

Due to the large technological gap between domestic PLC and foreign countries, the PLC used by my country's industrial enterprises in the 1980s was mainly imported. Some research institutions introduced foreign PLC products for localization research in order to achieve import substitution.

Before PLC was widely used, the control logic in machinery and equipment was implemented by groups of relays. The disadvantages of using relays are high cost, complex circuits, and easy failure. Once a failure occurs, it is very difficult to find the fault point.

PLC uses electronic components in integrated circuits to switch on and off the circuit. There are no electrical contacts, so it is less prone to failure. The control circuit of PLC is very simple, and even if a fault occurs, it is very easy to find, so it is very popular among mechanical engineers and maintenance workers.

Of course, not all electrical controls can be replaced by PLC. Relays are still widely used today, which involves some specific issues in mechanical design.

In the early 1990s, many domestic companies were already trying to use PLC to realize electrical control in machinery. However, because there were not many people who knew the technology, most companies were still shy about this technology. There are also some companies that could have applied PLC technology due to rigid leadership ideas and stuck to old rules, but still cling to product designs from decades ago without making improvements, which also leads to unsatisfactory PLC applications.

As a very large enterprise under the Ministry of Machinery, Linyi Machinery has always been well taken care of in the application of new technologies. In the early 1980s, the Machinery Department facilitated Linyi Machinery's introduction of CNC machine tool technology from RB Sakuma Co., Ltd., and carried out OEM manufacturing of several types of CNC machine tools for Sakuma Co., Ltd.

Linyiji has not been very successful in digesting imported technologies, but the application of PLC is not a very advanced technology, and Linyiji has a good level of mastery. The machine tools originally produced by Linyi Machinery were all controlled by relays. In recent years, they have been replaced by PLCs one after another, and the results are satisfactory. Han Weichang claimed that Linyi Machinery is the most professional in PLC applications. This cannot be completely regarded as bragging.

Mao Yaguang is also a knowledgeable person. The reason why he is willing to give Linyiji this opportunity is because he considers the strength of Linyiji and wants to see whether the baling machine produced by Linyiji is better than that of several established domestic companies.

He had people contact both Puji and Luoji, and specifically asked about technical issues related to electrical control. The other party claimed that there was no plan to switch to PLC control yet, which made Mao Yaguang a little disappointed.

"Pu Ji and Luo Ji are the emperor's daughters and they have no worries about getting married. Unless you buy foreign equipment, you can only buy their equipment. Since their equipment has no worries about sales, why bother with PLC control?" ?”

After listening to Mao Yaguang's introduction to the situation with Pu Ji and Luo Ji, Tang Zifeng analyzed the whole story for him.

"Assistant Tang is right." Mao Yaguang nodded in agreement, "Nowadays, the official-business style of some state-owned enterprises in the country is really serious. As for this metal baler, several private companies are already using PLC control, but Pu Machinery and Luoji still hold on to their original products. However, I am not too confident about these private companies. If the quality of hydraulic presses is a bit poor, big problems will occur. I don’t dare to use theirs casually. product. If you can produce a baler controlled by PLC, the price will be..."

"450,000 yuan per unit, no two prices." Tang Zifeng said flatly.

"320,000."

"440,000."

"340,000."

"430,000."

"345,000..."

"I'll do it!" Tang Zifeng looked up to the sky and sighed, "I said, Lao Mao, are you going to increase your salary by 5,500 like this? Look at your workshop, there are mountains of scrap steel. If you can add 4 more machines, you can How much extra money can you make in a day? You have time to negotiate with me about the price. Why not quote the actual price? Let's sign the contract quickly and we will produce the drawings according to your requirements. These 4 machines will be in place a week early, and the money you will earn will also be Is it more than 5,000 yuan?"

Mao Yaguang's face suddenly turned red, and he said: "Assistant Tang, it's not that I'm stingy, but the price of briquettes cannot be raised now. Many steel mills only want to cut steel, not briquette steel. In terms of briquette steel, ours The profit margin is very thin. I bought these four balers because we had too much backlog of light and thin scrap steel and had to get rid of it. From a purely profit-making perspective, I would rather sell sheared scrap steel."
