There are millions of building blocks, and every single one has to fit perfectly! 💡
For this to work, it’s not just about the machine, it’s mainly about using the right steel for the molds.
For this purpose, you could use 420FM tool steel, for example.
It offers good corrosion resistance, which is very important when dealing with moisture and processing aggressive plastics.
This steel is a good choice for plastic molds and offers an excellent combination of corrosion resistance, wear resistance, dimensional stability, and machinability.
Its excellent dimensional stability ensures that the famous bricks fit together perfectly!
An exciting example of how precision tool steel influences our everyday lives, often without us even noticing. 💪🏻
