Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary function?Manufacturing of vinyl records through compression molding
2. What is the core mechanism?Hydraulic press utilizing pressurized fluid to generate force
3. How does a record press make vinyl records?The press heats vinyl until it becomes soft, then places it with a label inside a heated mold. Two nickel stampers press the vinyl with about 150 tons of force, filling the grooves and bonding the label.
4. Why does a record press use so much pressure?The 150‑ton pressure makes the hot vinyl flow into every tiny groove of the stampers and keeps the label glued to the record. It is carefully calculated so the vinyl and stampers stay safe.

Hydraulic Press: A machine that uses Pascal's principle to generate immense force through pressurized fluid, enabling heavy-duty pressing operations.
Stampers: Precisely etched metal plates, typically nickel, that serve as molds to imprint audio grooves onto vinyl during pressing.
Compression Molding: A thermosetting plastic or composite manufacturing process where material is heated and compressed within a mold cavity to form a finished part.
Polyvinyl Chloride (PVC): A versatile plastic polymer commonly used for vinyl records due to its durability, acoustic properties, and moldability.
