"Don't underestimate me, a waste material company, it's a big deal to pick up rags now!"

Mao Yaguang took Tang Zifeng and Han Weichang to patrol the workshop, and at the same time said proudly:

"In recent years, the domestic steel market has been seriously in short supply, factories can't buy steel, steel mills want to produce steel, and they can't buy raw materials. Domestic iron ore mines are now producing like crazy, and some steel mills still import iron ore from abroad, but it is still far from enough. More than half of the country's steel mills are now using scrap steel as raw materials, and the buyers of those steel mills are lying in our company every day, waiting to collect scrap steel from us. ”

"Seeing that you can make a prosperous collection of rags here, it is really embarrassing to think that we have no food in a huge machine tool factory. Tang Zifeng said with emotion.

Mao Yaguang said: "That can only be blamed on the conservative thinking of the leadership of your factory." Think about it, there are more than a dozen prefecture-level cities in Xiahai Province alone, even if some prefecture-level cities are mainly agricultural, and there are not so many scrap steel recycling businesses, there are always five or six in a city like our Jinyao, right? One purchases four balers, adding up to more than 20 units. One is 200,000 ......."

"Stop, Manager Mao, your price is a bit underestimated, right?" Tang Zifeng hurriedly interjected. Let's just say that the thin man has a lot of eyes, this Mao Yaguang, who looks like he is giving advice to Linyi, secretly hid the private goods in it. If Tang Zifeng was a little sluggish and was surrounded by Mao Yaguang like this, maybe the price of a baler would be pressed to 200,000 by him.

"I'm making an analogy. Mao Yaguang was not embarrassed when the conspiracy was discovered, but continued: "This more than 200,000 yuan, I said it according to the past price." In the past two years, even the price of pork has risen, and the price of equipment has risen to 300,000, which is also okay, we understand. ”

"You imported it from abroad, it seems to be more than 50,000 US dollars a piece, which is 500,000 yuan. Tang Zifeng revealed.

"That's imported, imported equipment, it will definitely be a little more expensive. Mao Yaguang said confidently.

Tang Zifeng said: "You should know how expensive the foreign exchange indicators are now, right? We sell you a unit for 450,000 yuan, you don't lose money, and you save the foreign exchange index, isn't it very good?"

"However, if we are willing to spend 450,000 yuan to buy it from China, why bother looking for you to have a machine?" Mao Yaguang retorted, "Puji and Luoji are both professional manufacturers of balers, why don't I look for them?"

Tang Zifeng had also done his homework in advance, and knew that Mao Yaguang said that Puji and Luoji are veteran machine tool companies specializing in scrap steel processing machinery, and they have a high market share in the domestic market. The products of these companies are mature products with high user recognition, which is far from being comparable to the first machine. If Linyiji wants to grab business from the mouths of these enterprises, it is either to fight a price war and attract customers with low prices, or to bring forth the new and come up with some innovations that can impress customers.

Before leaving, Tang Zifeng specially discussed this issue with Qin Zhongnian, and Qin Zhongnian also put forward some innovative ideas, but these ideas still need to be recognized by Mao Yaguang to be useful. Listening to Mao Yaguang's words, Tang Zifeng smiled slightly and said, "Manager Mao, you're on point." Since Puji and Luoji can provide packing machines, why do you want to go far and go abroad to introduce them?"

"The quality of imported equipment is reliable. Mao Yaguang said, "We originally had two packers, three days and two ends of the problem, each time is not a big problem, at first we also called the manufacturer to come over to repair, and then we touched the doorway, we can repair themselves." But there are too many times it has gone wrong, and once it goes wrong, it will take at least half a day of work, who can stand it?"

"What's the main problem?" asked Han Weichang beside him. This is a problem involving technology, and Tang Zifeng is definitely not effective.

Mao Yaguang led them to the front of a baler and said, "Come and see, this is the baler we bought from Puji in the past, and it has been used for five years now. The first two years were fine, but in the next three years, it broke twice a month on average. The main problem is the circuit, there are more than a dozen relays on this machine, and there are hundreds of electrical contacts. Downtime can occur due to poor contact contact. In fact, it is very easy to repair this kind of contact failure, but it is a trouble to find the fault point, and you need to take the multimeter to measure it point by point, which is annoying to the individual. ”

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

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

Han Weichang said: "There are many more relays on our machine tools than on this baler, and there are thousands of electrical contacts. In the early days, our machine tools also had the problem you mentioned, that is, the contacts were easy to oxidize, resulting in poor contact. Later, we introduced technology from RB and replaced the relay with PLC, and these problems were solved at once. ”

"That's right, that's right, what I want is the C you said, what's the matter, can you do it in one machine?" Mao Yaguang asked.

"PLC, also known as a programmable controller. Now the domestic people who are engaged in this thing have to belong to us Pro Yi Ji is the most professional. Han Weichang boasted casually.

PLC technology originated from the United States at the end of the 60s, entered the practical stage in the mid-70s, and has been widely used in the 80s. In the early 70s, China carried out corresponding research, and in 1982, the domestic PLC was successfully developed, and it has been promoted in a small range. Due to the large gap between domestic PLC and foreign technology, the PLC used by China's industrial enterprises in the 80s mainly came from imports, and some research institutions introduced foreign PLC products for localization research, in order to achieve import substitution.

Before PLCs were widely used, the control logic in machines and equipment was implemented by a set of relays. The disadvantages of using relays are that they are costly, the wiring is complex, it is prone to failure, and once a failure occurs, it is very difficult to find the fault point.

PLC uses the electronic components in the integrated circuit to realize the on/off of the circuit, and there are no electrical contacts, so it is not easy to fail. The control circuit of the PLC is very simple, and even if there is a fault, it is very easy to find, so it is loved by mechanical engineers and maintenance workers.

Of course, not all electrical controls can be replaced by PLCs, and relays are still used in a wide range of applications today, which involves some specific problems in mechanical design.

In the early 90s, many domestic enterprises have tried to use PLC to realize electrical control in machinery, but because there are not many people who know it, most companies are still excited about this technology. There are also some enterprises due to the rigidity of leadership thinking, sticking to the old rules, could have applied PLC technology, but still hold on to the product design decades ago and do not make improvements, which also leads to the unsatisfactory application of PLC.

As a super-large enterprise under the Ministry of Machinery, Linyi Machine has always been very taken care of in the application of new technologies. In the early 80s, the Ministry of Machinery facilitated the 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. Linyi machine has not been very successful in digesting the introduction of technology, but the application of PLC is not a very advanced technology, and the degree of mastery of Linyi machine is still good. The original production of machine tools are controlled by relays, and PLC has been replaced by PLC over the years, and the effect is satisfactory. Han Weichang claimed that Linyi Machine is the most professional in PLC applications, which cannot be regarded as complete bragging.

Mao Yaguang is also a knowledgeable person, the reason why he is willing to give Linyi this opportunity is also to take into account the strength of Linyiji, and want to see if the baler made by Linyi Machine is better than those old domestic enterprises. He had people contact both Puji and Luoji, and asked about the technical aspects of electrical control. The other party claimed that there was no PLC control scheme for the time being, which made Mao Yaguang a little disappointed.

"Pu Ji and Luo Ji are the emperor's daughters, and they don't have to worry about marrying, unless you go to buy foreign equipment, you can only buy their equipment. Since their equipment is not sold, why bother with PLC control?"

Listening to Mao Yaguang's introduction to the contact with Puji and Luoji, Tang Zifeng analyzed the origin of the matter for him.

"Assistant Tang is right. Mao Yaguang nodded and agreed, "Now the official and business style of some state-owned enterprises in China is really serious. Let's just say that this metal baler, several private companies are already engaged in PLC control, but Puji and Luo Ji still hold on to the original products. However, for these private enterprises, I am not very assured, the hydraulic press, the quality of this thing is a little poor, the pool is going to be a big problem, I dare not use their products casually. If you can make a baler controlled by PLC, the price will be ......."

"450,000 units, no two prices. Tang Zifeng said categorically.

"320,000. ”

"440,000. ”

"340,000. ”

"430,000. ”

"345,000 ......"

"I'm down!" Tang Zifeng looked up to the sky and sighed, "I said Lao Mao, do you want to go up like this 55,000 land? Look at your workshop, the scrap steel is piled up into a mountain." If you can have 4 more machines, how much more money can you make in a day? You have time to negotiate the price with me, it is better to quote a real price, let's sign the contract quickly, and we will produce drawings according to your requirements. These 4 machines arrived a week earlier, and you made more than 5,000 yuan, right?"

Mao Yaguang blushed rarely, and said: "Assistant Tang, it's not that I pick the door, it's really that the price of briquetting can't be raised now, and many steel mills only need to shear steel, not briquetting steel." In terms of briquetting steel, our margins are very thin, and I entered these four balers because we had too much light and thin scrap and had to dispose of it. From a purely money-making point of view, I prefer to sell shear scrap. ”
