Or punching holes in a circuit board. It's all about controlled deformation.
So molds are about creating shapes from liquid or malleable materials.
Right.
While dies are shaping solid sheets by cutting or bending them.
Yes.
But it's not as simple as just mold for plastic, die for metal. Right.
Not at all.
Okay.
While it's true that molds are often used for plastics and dyes for metals.
Right.
There are exceptions. For instance, have you heard of die casting?
Vaguely.
Okay.
But it's not ringing any bells.
It's actually a metal shaping process.
Okay.
You inject molten metal into a die under extremely high pressure, creating incredibly detailed and durable parts.
Yeah.
Think intricate engine components. Or the casing for your laptop.
