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 is where the powder sits before it’s formed into tablets: a hopper. The hopper is a storage bin that holds the feed material and releases it into the die cavity at a controlled rate so each tablet gets a consistent amount of powder. This controlled flow helps prevent issues like overfilling or gaps, which would affect tablet weight and hardness.

The other parts aren’t storage before compression. The punch is the part that moves down to compress the powder. The die cavity is the space inside the die where the powder is packed during compression, not a reservoir for feeding material. Cam tracks guide the movement of the punches, not store powder.
