Preform Meaning in Simple English
Preform describes something made or shaped before its final stage.
This word often appears in production processes.
For example, a manufacturer may create a basic shape first. The company then changes that shape into a finished product.
Simple example:

That early shape is called a preform.
Therefore:
Preform = an early shape or form prepared for later processing.
This meaning makes preform different from perform.
