Chapter 472: Die Casting Machine

President Zhou was engaged in corporate reforms, and the movement was too loud. But in the machinery factory, it was much quieter, because many cadres and employees who were not officers were fired.
A security team composed of veterans and youths in Nantou Township is responsible for patrolling the plant. They have walkie-talkies connected to each other to ensure normal production in the factory.
Ding Wenjiang Dingong from Wuhan walked into the factory by his breastplate and saw that the high-power transformer outside the foundry had been installed.
With a stronger power supply, the equipment in the plant operates more reliably. Several new projects were launched in the reorganized machinery factory.
From 50cc to 250cc displacement, a total of seven sub-model two-stroke gasoline engines. This is an attempt to serialize the product line, and it is a technological breakthrough.
Since the 1990s, many domestic products have called themselves imported technologies. Motorcycle engines are also 'Japanese products'.
Zhou Qingfeng aims at import substitution. In the 1990s, there will be a large number of domestic production lines for automobiles and motorcycles, most of which will not last more than ten years.
However, within ten years, China imported a large number of small-displacement engines from Taiwan and Japan and South Korea. Money makes others make money, but their own industry has not developed.
It is better to be cheaper than others.
A two-stroke gasoline engine is the easiest, start with this. Hundreds of third-line engineers recruited by "Sacred Light" started work around this project.
Inspired by one, EFI control, turbocharging, high horsepower, low cost, low emissions, low fuel consumption, high reliability, and good maintenance, Zhou Qingfeng listed a series of dazzling super high indicators.
The idea is too advanced, one of the engineering staff inside the company counts one, all shaking their heads and feeling incredible.
But Mr. President really moved out the corresponding model of ‘imported from Japan’ motorcycle engine and came up with a corresponding design plan.
It's one thing to do it or not, but you have to work hard!
Zhou Qingfeng convened a meeting of engineering staff. "With our current technical level, it is really difficult to build this series of engines. But this is not the reason we lowered our target.
I also talked about using American Standards instead of the currently used Soviet Standards. Now we have to start thinking about those in the American standard that we can do, and those that we can't.
Among the indicators that cannot be achieved, those are the ones we can overcome to overcome difficulties. Those are things we can't overcome. Those are the ones we don't understand and have no idea at all. "
In the chaos on the Tianyang market, the entire company of ‘Shengguang’ was catching ducks on the shelves and preparing to tackle the ‘world ’s advanced level’ two-stroke gasoline engine.
Ding Wenjiang is engaged in casting, and the cylinder blocks of seven models must be cast first. In order to reduce costs while ensuring performance, casting needs to be precise and reduce machining timing.
Lao Ding came to the foundry today to see the production capacity of Tianyang Machinery Factory.
Before entering the workshop, someone shouted loudly at the door: "Lao Ding, come quickly. Show you a good baby."
Shouting is the old master Zhang Ding Wenjiang knew in the original unit, which is responsible for mold turning sand. He beckoned constantly at the door, pulling the old man to a large equipment in the workshop.
"What's this?" At first glance, Ding Wenjiang felt that the device looked like a horizontal machine tool, but he looked closely but it was not a machine tool. "This is, a die-casting machine?"
Old Ding's surprised soul is about to fly out.
Vehicle engines are mostly cast iron or cast aluminum, each of which has its own benefits.
Starting from the domestic technical level, Ding Wenjiang recommended an upgrade route for cast iron engines.
He eloquently wrote a dozen-page report, and only wrote about the benefits of cast aluminum in the last half of the page. He also mentioned, ‘cast aluminum requires a die-casting machine’.
The report was handed in and Zhou Qingfeng called that night. The president didn't even mention the dozen or so pages that he had worked so hard to write, and asked only the last short piece of "die casting machine".
After asking for a long time, Zhou Dabang gave a ‘oh’ sound, as if he understood it. But Ding Wenjiang dared to bet that his CEO didn't understand, at most he understood that the die casting machine had high production efficiency.
Die-casting is to inject molten metal into a mold and cool it. After opening the mold, the desired metal parts can be obtained. It's just like an injection molding machine, except that the latter is filled with melted plastic particles.
Ordinary sand casting is particularly troublesome. There are too many processes for modeling, core making, pouring, cooling, falling sand, cleaning, machining and heat treatment.
As long as the mold is prepared for die casting, cooling after casting is basically the finished product. The casting has high precision, fast speed and low cost. Engines such as cars and motorcycles are often used for this.
It is commonly known that v always says that the competitiveness of domestic products is low labor costs. Such people just don't have a mind, they don't understand what is called industry, and they don't know what is mechanized manufacturing.
The biggest feature of industry is to replace people with machines, reducing the proportion of manpower in product costs. In the face of large machine production, there is an egg for low labor costs.
A hundred low-end laborers can't reach a good machine. The machine does not require five insurances and one fund, operates 24 hours a day, and does not take leave or work late.
Industrial development is constantly eliminating low-level jobs.
Come back to die casting.
There are advantages and disadvantages to die casting. The biggest disadvantage is that if the equipment is not designed and manufactured, it is easy to leave air holes in the finished product and become waste.
In addition, because of the high melting point of cast iron, die casting cannot be used. The material of the hot chamber die casting machine is zinc alloy, magnesium alloy. Cold chamber die casting machines can handle aluminum alloys.
At present, domestic electricity is not sufficient, and the output of aluminum alloy is not high at present, which is far lower than the price of cast iron.
Lao Ding comprehensively considered that good die casting machines must be imported, which is too expensive. I am afraid that the raw materials are not easy to buy. He recommended the cast iron route to Uncle Zhou.
This is also a consideration of domestic technological level.
But this Zhou Zhaipi, I wrote a few days' report, he actually only looked at the last few sentences.
Say yes, be cautious when choosing a technical route? My old man racked his brains and thought it over, and you finally got the die-casting machine.
Having said that, you should also consider the cost when referring to international standards, which is in line with the current domestic situation. Aluminium is more expensive than iron, don't you know how to skin it all week?
You are a big mallet. When you have a meeting, you keep talking with one mouth. Can you fart?
Ding Wenjiang was angry and happy, making several rounds around the horizontal cold room die casting machine, laughing. He pulled the sandmaker Lao Zhang and asked, "Where did this good thing come from?"
Lao Zhang said: "The equipment we just arrived today is looking for someone to figure out how to install it. President Zhou said that with the die casting machine, not only can engine cylinders be produced, but many body parts can be die cast.
As long as we make the mold, no matter whether it is a car or a motorcycle, it will be the same as making sausages. "
The old man listened to the joy, and then he danced on the spot. But he jumped for a while and asked in anxiety: "Of course it is good to have a die-casting machine. But what about aluminum? There are not many aluminum materials in China."
Lao Zhang lowered his voice, "I heard that President Zhou smuggled a large amount of scrap aluminum from abroad. Isn't there a small steel plant in the city, and that plant has now fallen into his hands and is subject to restructuring.
Also, many people have been laid off recently and have lost their jobs. ‘Harmonious Recycling’ is recruiting people for the past two days, and it requires five hundred waste screeners.
It is said that there are too many impurities in the scrap aluminum and iron, which need to be manually cleaned up. The salary is not low, but this job is not good, and some people are not willing to do it.
But let me say, this person can't be too lyrical. "
Enterprise reform is naturally good. Keeping the business as it is is not only the death of the company, but also the death of the whole society. Because the wages paid to those wastes are hard earned by people in other industries.
But so many people are now unemployed.
The old man shook his head and sighed longly: "This week's great mallet, the work is impatience. Can't he be expelled slowly? He can only expel 20,000 in one breath. This is the only thing he can do."
After that, I suddenly yelled at the door of the workshop, "Who is calling me 'Chou Dabangmao' from day to night? Do you disagree with me?"
Suddenly in the workshop, everyone looked at Ding Wenjiang.
The old man was very old and was frightened. He turned to look at Zhou Qingfeng and had to point to the die-casting machine that had just arrived and said, "Zhou, misunderstanding. I'm a boast of the die-casting machine."
Zhou Qingfeng appeared in the foundry, folded his arms, and said angrily: "Are you stupid of me? Explain it to me, don't explain it clearly, and deduct half a month's salary."
"This" week "is a particularly comprehensive function of the die-casting machine." Big "means that the mold-clamping force of the die-casting machine is particularly strong. Of course, the" rod "is a special stick of the die-casting machine. As for the" hammer "?
For a long time, Ding Wenjiang did not come out of the mallet. He looked at Lao Zhang, who was five meters away from him.
Zhou Qingfeng couldn't help crying and laughing, "How do you call a‘ big mallet ’in Wuhan?

The old man explained: "I'm not from Wuhan, I'm from Liaoning."
"Okay, no matter where you are. Give you half a month to install and debug this die casting machine, and train at least ten qualified operators at the same time. Otherwise I will deduct your salary for one month.
I want to see who is the mallet? !! "
