For example.
Many components of the Airbus A380 are manufactured by Da Mao's hydraulic press, which is rated at 75,000 tons.
The domestic 80,000-ton water press is mostly used for producing 7500mm nuclear power plant tube plates and forging fighter jet engine frames, among other things.
One-time molding, no need for second forging.
This is truly a vital national asset, and there's only one in the country.
When creating precision equipment like ring dies without a pre-mold, just starting it up costs over a million. (The cost of the 80,000-ton water press is ten yuan per ton.)
The molds made under such circumstances can be directly used for replica mass production.
In other words, you follow the pattern with molten iron, pour into it, and after cooling, you get the necessary ring production line directly, which naturally is not low in cost.
Of course.
The above sentence is just an example, for ease of understanding.
