1. Machine Speed (Capacity) Calculation

What is Machine Speed?

Machine speed determines the theoretical maximum number of capsules an encapsulation machine can produce within a specific period.

The output depends on:

• Number of machine cycles
• Dosing disc configuration
• Number of holes/stations
• Equipment design

Factors Affecting Machine Speed

Parameter	Effect on Output
Powder flowability	Filling consistency
Capsule size	Machine throughput
Machine vibration	Weight variation
Product stickiness	Downtime increase
Dust generation	Cleaning frequency

2. Rejection Rate Calculation

What is Rejection Rate?

Rejection rate measures the percentage of defective capsules rejected during production.

Rejected capsules may include:

• Underweight capsules
• Overweight capsules
• Improperly locked capsules
• Split capsules
• Empty capsules

Common Causes of Capsule Rejection

Defect	Possible Cause
Weight variation	Poor powder flow
Capsule separation	Improper locking
Empty capsules	Feeding issues
Cracked shells	Excessive machine force
Powder leakage	Incorrect capsule alignment

3. Utilization (OEE) Calculation

What is Utilization?

Utilization measures how effectively production time is used compared to planned production time.

It accounts for:

• Cleaning downtime
• Changeovers
• Maintenance
• Material replenishment
• Machine stoppages

OEE Components in Pharmaceutical Manufacturing

OEE Component	Description
Availability	Machine uptime
Performance	Actual vs theoretical speed
Quality	Good capsules produced
