What are the manufacturers of Xiamen double door panel molding machine?

Fasteners are actually screws, nuts, screws, self-tapping screws and other parts that we use to fix. From glasses on the bridge of the nose to airplanes, high-speed trains and ships, fasteners are called "industrial instruments". Even the best dishes should be accompanied by rice, and even the top-grade accessories should be connected by fasteners. This description is enough.

Some people disdain, screws are everywhere, what technical content can there be! In fact, upgrading a small screw is often much more difficult than some "tall" projects. A small fastener reflects the development of manufacturing in China.

Today's "strong province specializing in special new manufacturing" takes everyone into Zhoushan 74 12 factory.

At least 7 of every 10 passenger cars in China have their fastener products;

More than ten kinds of fastener products were loaded on the turbine engine of the Red Flag parade vehicle on the 60th anniversary of the National Day.

"High-strength fasteners for automobiles" and "high-temperature-resistant fasteners" are at the leading level in China;

Not only the suppliers of many multinational automobile giants, but also the "Wuling Shenche" and "Weilai 3-minute fast power exchange" can not be separated from their support. ...

There are many brands standing behind them, establishing a stable supply chain, jointly developing new products and supporting the development of China automobile industry.

"The soldiers shouldered the burden and knocked on the door of the big factory."

Thirty-five years ago, it was difficult for military families who came to Zhoushan with the army to find jobs. The superior party Committee decided to set up a screw and nut factory with a registered capital of no more than 5,000 yuan. The conditions were tough, but the quality of the products produced by the navy was not bad, and an urgent order was quickly received from Tianjin Li Xia.

Sining: This is the first time I have received an order from a "big factory"! Whether it can be completed is actually very risky.

Chen Yifeng: Yes, this is also the legendary story of our factory's market development. At that time, I received an urgent demand from Li Xia. In fact, they don't know us well enough. Our old factory director said at that time, don't worry about the quality, I will be responsible for the problems. The traffic on the island is very inconvenient. At that time, it usually took more than a week from Zhoushan to Tianjin. In order to catch up with the delivery, our soldiers carried two baskets of screws on a pole, worked day and night, and finally delivered them to Tianjin Li Xia factory in the early hours of the deadline. This is equivalent to a pioneering work, which opened the door for our factory to enter the automobile industry for the first time.

Sining: The pace of going out never stops.

Chen Yifeng: Yes. 1990, Beijing jeep was localized, and six fastener factories were found in China to develop self-tapping and self-locking bolts for triangular rods. Only we succeeded.

Around the Millennium, the automobile engine changed from the traditional air-breathing engine to the turbocharged engine, which put forward higher requirements for engine fasteners and needed to withstand the high temperature of 500-600 degrees. At first, this high-end fastener needed to be imported. In fact, the biggest difficulty is the research and development of raw materials. Together with raw material suppliers, we have developed this high-temperature resistant material in China again.

For so many years, 74 12 Factory has never stopped research and development. Now our heat-resistant stainless steel products are in a leading position in China, with constant strength and no oxidation and deformation at 900℃. At present, in the domestic market, 70% of the high-temperature resistant fasteners on buses are produced by our 74 12 factory.

The host Sining wore protective clothing to witness the opening moment of the high-temperature "well furnace"

The temperature in the furnace can reach 1200 degrees Celsius, and the forged fasteners can withstand 800 degrees Celsius.

The mysterious power behind the rapid power exchange between Wuling shenche and weilai

"Floating Nut" developed by 74 12 Factory for Weilai Automobile

In June 5438+10, the second generation power station of new energy automobile brand "Weilai" was officially released. 3 1 s can complete the whole step of installing the unlocking nut of the unlocking gun, which is stable in connection and reliable in repeated separation, and has attracted wide attention. The key core component "floating nut" used in this step comes from Zhoushan 74 12 factory.

"What the people need, what Wuling will build" is a short video platform, and different models need to develop different fastener products. 74 12 Factory can be called the hero behind the "Wuling God Car". Whatever fasteners Wuling needs, 74 12 Factory will develop them.

Sining: Now the 74 12 factory has entered the market. Is it your strength to conduct research and development according to the needs of car companies?

Chen Yifeng: With the continuous iteration of the customer model, we must meet the needs of customers and develop corresponding products. For example, we have developed a "floating nut" for Weilai automobile, and there is a certain gap between the parts combination, which is convenient for the robot to jack up the automobile battery, find the nut and change the power quickly.

Sining: Why did Weilai go to the 74 12 factory on the island to solve this technical problem? What is the biggest difficulty?

Chen Yifeng: The difficulty lies in "floating". It is necessary to maintain relative stability and leave room.

In addition, it is necessary to solve the initial temperature pier forming process. The hot working process of raw materials is heavy, and the positive and negative temperatures cannot exceed 10 degrees, which puts very high demands on the control in the process, and we have also improved the production equipment for this purpose. Why we chose our factory is also because of our position, reputation and reputation in the industry. In fact, we have always been the supplier of JAC and the main engine factory of Weilai Automobile, and have always been the cooperative relationship between * * * and development * * * and breakthrough, and established full trust. Look, the floating nut in your hand is a rectangle, and mine is a diamond.

Sinning: The floating range of diamonds is relatively large.

Chen Yifeng: Relatively speaking, it has more room.

A car needs more than 6,000 fasteners, with more than 2,000 types and models. In the past, what we did was what the country needed. Now our innovation is that we will develop what the terminal car factory needs and what the market needs. You can go to our product exhibition area upstairs. There is a whole row of fastener products developed for Wuling automobile.

The fastener products used on the "Wuling God Car" surprised Sining.

Sining: There is a very popular saying on the Internet, "People need it, Wuling will build it". For 74 12 factory, it means that "Wuling will build whatever fasteners it needs".

"The more inconspicuous the part, the more difficult it is to update the iteration."

Chen Yifeng: In the past, everyone thought that screws and nuts were very simple. In fact, the simpler things, the more difficult it is for you to update the iteration, and the technological breakthrough is not the most difficult.

Sining: Actually, we all need to start with raw materials?

Chen Yifeng: Not only that, it also involves the upgrading of raw materials, the improvement of processing equipment, the research and development of processing technology and the subsequent surface treatment. Every item should be strengthened to make excellent screws.

Xin Ning: It is not something that an enterprise can do.

Chen Yifeng: Yes. Look at large aircraft, aerospace, automobile and other manufacturing industries. In our country. As small as titanium alloy fasteners for dental implants, many of them still rely on imports. I believe everyone can understand how expensive a screw is when planting teeth. This is the embodiment of the added value of the product. So we still have a long way to go.

Chen Yifeng: This year, we jointly established the "High-end Fastener Research Institute" with the Institute of Materials of Shanghai University, focusing on the development of high-end fastener products in the automobile industry, shipbuilding industry and aerospace industry listed in the national industrial structure adjustment guidance catalogue, hoping to promote the integration of Industry-University-Research and reserve technology and talents.

Moderator's Note: A small fastener reflects the development course of China manufacturing, and the entrepreneurial course of Zhoushan 74 12 Factory is actually a microcosm of the high-quality development of Zhejiang manufacturing.

In 35 years, from a screw factory established to solve the employment of military families, it has grown into a first-class supplier highly recognized by many international first-class automobile brands; In the past 35 years, from a small factory with a registered capital of 5,000 yuan, it has grown into a national key specialized new giant enterprise with more than 5,000 products and serving more than 200 customers; "Made in Zhejiang" brand certification, Zhejiang provincial government quality award nomination award, national laboratory, invisible champion, green factory ... Zhoushan 74 12 factory, all the way forward, all the way through, we look forward to more surprises from the future 74 12 factory.
