How To Change Mold of The Tablet Press

Here is a concise step-by-step guide for replacing dies in a tablet press machine.

Following these steps ensures efficient and safe die replacement while maintaining tablet quality. Procedures may vary slightly depending on the machine model—always refer to the equipment manual.

1. Preparation

• Power Off: Ensure the tablet press is turned off and disconnected from the power supply.

• Clean the Die Area: Remove any residual powder or debris to avoid contamination.

• Gather Tools: Prepare necessary tools (e.g., wrenches, pry bars, gloves) and new dies.

2. Removing the Old Dies

• Loosen Fasteners: Unscrew the clamping screws or plates securing the upper punch, lower punch, and die table.

• Extract the Dies: Remove the upper punch, lower punch, and finally the die (die table) in sequence.

• Inspect Old Dies: Check for wear and decide whether to discard or refurbish them.

3. Installing New Dies

• Install the Die: Place the new die into the die table slot, ensuring it sits flat before tightening the clamp.

• Insert the Lower Punch: Fit the lower punch into the die hole and adjust its height before securing it.

• Install the Upper Punch: Insert the upper punch, ensuring proper alignment with the die hole, then tighten the screws.

• Manual Test: Rotate the handwheel to verify smooth movement without jamming.

4. Calibration & Verification

• Adjust Pressure & Fill Depth: Set parameters (pressure, thickness, etc.) according to production requirements.

• Test Run: Conduct a dry run to check for abnormal noises. Perform a trial compression with minimal material to inspect tablet quality (weight, hardness, surface integrity).

• Fine-Tune: Adjust pressure or fill depth based on test results.

5. Completion

• Clean Up: Clear tools and debris. Document replacement details (die serial number, time, etc.).

• Resume Production: Restart the machine and closely monitor tablet quality during initial operation.

Key Notes

• Safety First: Wear protective gloves to prevent pinch injuries.

• Proper Alignment: Ensure precise alignment of punches and dies to prevent eccentric wear.

• Lubrication: Apply food-grade lubricant (e.g., magnesium stearate) if necessary.
