Toy giant Lego factory first exposure
Lego is known as the top secret, even if the media is not allowed to enter the holy place of photography, it is a LEGO factory! I remember that when the LEGO China factory opened, I invited a lot of media, but when I finally entered the factory, I was not allowed to take pictures.
Today, the savvy designer Sariel from Poland has finally led us to uncover the core of the ninth largest mysterious institution in the world (why 9? Don't care, I edited it)!
Saariel is a master of science and technology design from Poland, and his work is even appreciated by Lego:
It is because of his hard work and dedication in the LEGO circle that he was invited by Lego to visit the Lego factory!
Let's start this trip to the Lego Holy Land! The first to enter is the LEGO ABS pellet warehouse.
The ABS particles themselves are not Lego particles, but pellets. Let's see what these ingredients look like.
Generally, these building block manufacturers in China are all packed in hemp bags. (I know what I know? Because I visited the domestic building block production workshop, we will compare it later)
At Lego's building block factories, most of them have implemented automated robot control, including ABS warehouses, which use robots to select transportation materials.
At the same time, Lego cooperates with dozens of raw material suppliers. If they strike collectively one day, I believe that this workshop will die in 4 days.
Then enter the warehouse of Lego Mould! This is the vault in the LEGO workshop! Why do you say that? Because we can describe this, the entire Lego parts production process, the cost of making this mold is the highest, the highest precision requirements.
In fact, the use of these molds is quite simple, that is, open the two sides of the mold, inject ABS raw materials, and close it. It feels like baking in our home. However, because of the accuracy error requirements and wear requirements, this technology is the heart technology of LEGO parts.
Next, enter the injection molding machine workshop of the LEGO factory! There are countless injection molding machines that continue to operate to produce LEGO parts. The more machines, the greater the capacity.
Did everyone see these "plastic dollars"? In the Lego factory, it seems that it is just a pile of worthless plastic. In our opinion, it is simply a pile of gold! A pellet market price is at least 5 cents (RMB)!
A wide variety of parts are sent from the conveyor belt.
This process shows the robot arm, how to take out the waste after the production of the parts, that is, directly to the waste bin that is pinched and thrown to the side.
Everyone saw this machine brand not! Hey, this is the 4000001 injection molding machine we are buying recently!
Of course, the latest technology is now more advanced. Off-topic, we have the last two injection molding machines , and interested friends can enter the purchase in the group purchase article below!
The entire machine tool uses a water cooling system to cool down.
When the part is produced, the robot removes the tray full of parts and replaces it with an empty tray. The trays filled with parts are transferred to a conveyor belt and taken to another location.
At the same time, some waste will be produced during the injection molding process. Just as we play the Bandai model, there will be some external plastic shelves that support the middle parts, like this:
This is an exaggerated picture of the mold forming process, but you can see what the molded parts look like.
Then you enter another small black house, which is the warehouse of Lego parts.
All of them are a few-story library of parts (like the warehouse of our MOC God, but magnified n times). All access is controlled by the robot, and there is almost no light in this room. After all, no humans are needed, saving power.
If there is a problem with the robot, use these "inconceivable" tools to fix it!
Finally, it is the central control. All the workshops and machines are controlled by the system.
Some indicators of storage equipment.
From the workshop, I went to the finished product display area (Reminiscence Avenue). Here we briefly introduce the following, after all, it is not too novel, it is the products that have been seen on the market, and there are some Lego statues.
Here, you can find almost the perfect box of all the sets that are out of print!
Sariel also found his first Lego particle building blocks and tech blocks! See here, our Lego tour will end!
What is the difference between the LEGO factory and the domestic building block factory?
Our "Building Circle" WeChat public account has visited the domestic building blocks production workshop before, and also looked at LEGO's production workshop, so there is still a comparison between the two.
The current domestic injection molding machine technology is very mature! This will not fall behind Lego, such as the common online:
These are the current mainstream injection molding machines in China. In fact, in the past 1 or 2 years, we have seen many domestic brands plagiarizing Lego, and we know that our technology has improved. Ok, this is a black history.
However, the LEGO factory has a very high degree of automation, and there are few opportunities for people to participate. For example, the parts shipped from an injection molding machine and the replacement of new pallets are the simplest manual operations in the country, directly thrown on the ground, how much is produced at one time. Enough, stop and change.
After all, foreign countries are very concerned about human rights and health. In the process of plastic production, there will inevitably be toxic gases. So basically it's automated.
The other is the difference in the level of making the metal mold. Why are the machines that produce building blocks in China all the same, but the products are still different? Because the engineer who made the mold is there!
As the saying goes, the cost of opening the mold is the highest, and according to the current parts of LEGO, we also counted the use of parts in the past 10 years. In 10 years, the number of parts used is not counted as color. Only over 1000 times, there are 150 models. Components:
The cost of opening this high-frequency part of the light is close to 10 million in millions. Let's not mention those biochemical series and special parts.
