Pressing pills, also known as tablet compression, is a crucial process in the pharmaceutical industry, ensuring that powdered or granulated substances are formed into solid, uniform tablets. Here's a basic guide on how pills are pressed:

1. Prepare the Powdered Material

· Blending: Ensure the active ingredients and excipients (like binders, fillers, and lubricants) are evenly mixed. This creates a homogenous blend necessary for consistent tablet quality.

· Granulation (if needed): Convert the powder into granules to improve flowability and compressibility. This step may involve wet or dry granulation processes depending on the material's properties.

2. Load the Material into the Hopper

· Hopper: The blended or granulated material is placed into the hopper, which feeds the material into the tablet press. The hopper ensures a steady supply of material to the die cavity.

3. Fill the Die Cavity

· Die Filling: The material is transferred from the hopper into the die cavity. The lower punch of the tablet press is adjusted to control the amount of material that enters the die, determining the tablet’s weight.

4. Compress the Material

· Pre-Compression: The upper punch applies light pressure to remove any air from the powder, forming a loose compact known as a "slug."

· Main Compression: Higher pressure is then applied to compress the material into a solid tablet. The pressure must be carefully controlled to ensure the tablet's strength and integrity.

5. Eject the Tablet

· Ejection: The lower punch rises, pushing the finished tablet out of the die cavity. The tablet is then collected and inspected for quality.

6. Quality Control

· Inspection: Tablets are inspected for consistency in weight, hardness, and appearance. Any tablets that do not meet the required standards are discarded.

7. Packaging

· Packaging: Once the tablets pass quality control, they are packaged for distribution. This step may involve blister packing, bottling, or other packaging methods.

Pressing pills requires precision and consistency to ensure that each tablet meets the required standards for dosage, size, and strength.
