What is a radiator

Radiator is the heat exchange product of automobile engine. Its main function is to cool the heat generated by the engine, so that the engine can work stably for a long time. At present, the most popular radiator is made of aluminum, because the price of aluminum is very cheap, and the heat exchange efficiency of aluminum radiator is better. All automobile factories or after-sales markets use aluminum radiator as the first choice.

Automobile radiator usually consists of three materials, namely aluminum material, EPDM and PA66-GF30. Aluminum material includes aluminum plate, aluminum foil and aluminium tube. Each aluminum material has a different brand. Generally, the brand of aluminum plate is 4343/3003/7072, the brand of aluminum foil is 3003, and the brand of aluminium tube is 4343/3003/7072.

Note: The radiator production line we introduced does not include equipment for aluminum production.

EPDM materials are used to manufacture gaskets. radiator factories in China directly purchase complete gaskets. Because the price of gaskets is very cheap, the cost of gaskets for each radiator is about 0.5-0.8 USD.

PA66-GF30, This material is used to produce a radiator plastic tank. After being melted at high temperature, the material is hydraulically injected into the cavity of the mold, and then cooled and shaped to form a complete radiator tank. Finally, the tank is assembled with the aluminum core of the radiator.

What are the machines in the radiator production line?

Fin production machine

This machine is used to produce fin of radiator. It is a fully automatic high-speed machine. It uses two high-precision rollers to roll the aluminum foil to form the desired shape, and then cut it according to the set length. The maximum production speed of this aluminum fin machine reaches 120 meters per minute. The roller mold can be compatible with 0.07-0.12mm aluminum foil. Usually, small-scale production of radiator factories only need one fin machine.

Aluminum brazing furnace

The aluminum brazing furnace is the most critical machine in the radiator production line. It is one of the most important technologies for producing aluminum radiator. In the past, engineers needed to precisely control the temperature of the brazing furnace and the operating speed of the brazing furnace. However, with the rapid development of industry, the brazing furnace we supply uses an intelligent control system. Engineers only need to master simple operating methods. Even a new engineer can get high-quality aluminum radiator cores.

Aluminum core assembly machine

At present, there are many solutions for aluminum core assembly, but the best choice is to choose the most suitable solution based on your production volume rather than the most suitable one. If you are a new factory, we recommend that you choose semi-automatic machines. Semi automatic machines are very easy to replace models or repair faults.

The fully automatic assembly machine is suitable for mass production of one size of radiator, and it is suitable for OEM factories, because it takes a long time to replace the model of the fully automatic production machine. Here are two videos of the machine, the fully automatic machine and the semi-automatic machine. You can view the video.

Generally, radiator factories in the after-sales market will choose semi-automatic machines. If your factory produces 2000-5000 radiator every month, your factory only needs one machine. If your factory produces 10000 radiator every month, you may need two cores to assemble the machine.

Cramping machine for plastic tank

This machine installs plastic tanks and aluminum cores together because each plastic tank has a different shape and many obstacles. To avoid collisions when installing plastic tanks, you need a machine that can preset pressing steps.

The equipment of this radiator production line can set working formulas according to different types of products, and intelligently avoid obstacles. It can produce 20-30 radiator per hour. A small-scale radiator factory can meet all production needs with only one machine.

Sealing testing machine

When the radiator is assembled, it needs to undergo a sealing test before leaving the factory. Yes, every radiator needs to undergo a 100% sealing test, which is a must for every responsible factory.

The working principle of the sealing test is to completely seal the radiator, and then the machine will apply pressure to the radiator for 60 seconds. If the pressure of the radiator does not drop, the machine will judge that the radiator is perfect. If the pressure decreases, then the radiator has leakage.

The minimum detection pressure of the machine is 1 pa, that is, when the pressure inside the radiator is reduced by 1 pa, the machine can successfully catch the leakage value, which is very accurate and efficient.

Other machines of radiator production line

Smallest radiator factory

At present, there are many small-scale copper radiator factories in the global market. Due to the rapid development of AI industry in recent years, as well as geopolitical and war, the price of copper materials has risen rapidly. Many copper radiator factories want to start small-scale production of aluminum radiator, because they lack technology, they do not know where to start.

First of all, the brazing furnace of copper radiator is cheap and does not need high manufacturing technology, so copper radiator is very suitable for small-scale production, but the factory of aluminum radiator is different, because the price of aluminum brazing furnace is very expensive, and the price of a smallest aluminum brazing furnace is about 130000 USD.

Secondly, the working temperature of the aluminum brazing furnace is 600 ℃ -620 ℃. The brazing furnace needs nitrogen to protect the aluminum materials from oxidation during the working period. Engineers need to master more experience and technology, and this radiator production line requires at least 2 engineers and 10 workers to participate.

Third, if your factory plans to produce 2000-5000 aluminum radiator every month, and all the parts are from China, then the price of all the machines in this factory is about 200000 USD, and you need a factory with 1500-2000 square meters, and the cost of purchasing raw materials is about 100000 USD -150000 USD.

These are the most basic investment amounts, and the actual situation may vary. You can use them as a preliminary budget. If you still want to produce stamped parts and plastic injection parts, you can contact us for more details.

What is the prospect of investing in radiator production line?

At present, automobile after-sales maintenance is a huge market. If you start to produce aluminum radiator, this is a very good business. But before starting this business, you need to know the car market in your country. Which car brands and models have more share. You can choose 10-20 radiator with higher share, and then you can start this business.

Not only that, when you have a complete radiator production line, those machines can also produce condenser for automobile air conditioners, microchannel condenser for household air conditioners, and small-scale plate and bar type heat exchangers But you need to invest a little money to buy some fixed tools and stamping mold.

In many countries, there are also automobile assembly factories. In order to support the local manufacturing industry, the local government usually has some policy support and trade protection measures to encourage its citizens to invest in the manufacturing of automobile parts. If your country also has this situation, then don’t hesitate, start this factory now.

What technologies need to be mastered in radiator production line

Aluminum brazing technology

This is one of the most important technologies for producing aluminum radiator, because there are many radiator of different sizes in the radiator factory. The temperature required for each aluminum core to enter the brazing furnace is different, and we cannot see the aluminum core inside the brazing furnace. Engineers can only control the temperature by relying on experience. In order to solve this technical problem, we will set a perfect temperature for the brazing furnace. The new engineer only needs to adjust the operating speed of the brazing furnace, which can effectively improve the quality of products.

In addition, we have also installed an intelligent control system for the brazing furnace, and engineers can preset the process flow for each radiator. When you produce the radiator you need, you can call it with one key, which is very fast.

Parts cleaning technology

Every material of the aluminum radiator core needs to be cleaned by the ultrasonic machine. If there is oil residue on the surface of the part, it will become black after high temperature, which seriously affects the appearance of the aluminum radiator. If the oil is in the gap position, it will affect the quality of brazing, and the aluminum core will leak.

It is a popular saying in the industry of producing aluminum radiator that the cleaner the aluminum parts are, the more beautiful the aluminum core is, the better its quality is.

Production technology

There are many different machines in the radiator production line, and the operation mode of each machine is different. Your factory needs an engineer to master these machines, control these machines smoothly, master and adjust the machines to produce different types of radiator skillfully.

The above technologies must be mastered, which determines whether you can produce high-quality aluminum radiator. In addition, there are many aluminum radiator with only slight size differences, that is, two different radiator are very prone to errors in the production process. Therefore, it is a very critical task to sort out all radiator and draw a design drawing for each radiator.

The above is the whole content of this article. If you need to know more details about the production line of automobile aluminum radiator, you can contact our engineers, and we will answer every question for you.
