The component that stores feed material before compression is called which?

• A. Hopper
• B. Punch
• C. Die Cavity
• D. Cam Tracks

Answer: (A)

The main idea here is where bulk material is kept before it’s pressed. The hopper sits at the top of a tablet press and acts as a reservoir for powder or granules, feeding the material in controlled amounts into the die cavity during each cycle. It’s designed to hold enough material to keep the press running smoothly and to prevent interruptions from refilling or flow issues. The die cavity is the hollow space inside the die where the actual compression happens, so it’s used to receive material just before and during pressing, not as a long-term storage container. The punch is the moving part that pushes the material into the die, and cam tracks control their motion. So, the component that stores feed material before compression is the hopper.
