🔍 Inspection Machines: Quality Control in Action

What Are Inspection Machines?

Inspection machines are used to detect physical, visual, or chemical defects in pharmaceutical products such as tablets, capsules, vials, and ampoules. These machines serve as the last line of defense before packaging and distribution, ensuring only high-quality products reach consumers.

Types of Inspection Machines

1. Tablet and Capsule Inspection Systems

   • Detect broken, chipped, deformed, or contaminated tablets and capsules.

   • Use high-resolution cameras, laser sensors, and vision algorithms.

2. Ampoule/Vial Inspection Machines

   • Check for particulate matter, fill volume, sealing defects, and cosmetic issues in injectable containers.

3. Blister Pack Inspection

   • Verifies correct placement and integrity of tablets/capsules in blister cavities using vision or sensor-based systems.

4. Metal Detection and Checkweighers

   • Identify foreign metallic contaminants and verify the weight consistency of final products.

Key Technologies Used

• Machine Vision (2D/3D imaging)

• AI-based Defect Classification

• Laser and Infrared Scanning

• High-Speed Rotating Cameras

• UV Light & Fluorescence Inspection

Benefits

• 100% product verification

• Faster defect identification

• Improved regulatory compliance (FDA, GMP)

• Integration with serialization and track-and-trace systems

💊 Tablet Presses: Core of Solid Dosage Manufacturing

What Is a Tablet Press?

A tablet press, also known as a tablet compression machine, compresses powders into uniform tablets using dies and punches. It is the most critical step in tablet manufacturing, determining shape, size, weight, and hardness.

Types of Tablet Press Machines

1. Single Punch Tablet Press

   • Suitable for small-batch production and R&D.

   • Simple, low-cost, and compact design.

2. Rotary Tablet Press

   • Designed for high-speed, high-volume production.

   • Equipped with multiple tooling stations rotating around a central axis.

3. High-Speed Tablet Press with Auto Control

   • Features automated weight adjustment, force monitoring, and rejection mechanisms.

   • Supports continuous production with minimal manual intervention.

Key Features and Technologies

• Pre-compression and main compression stations

• Touchscreen control with recipe management

• Force feeders for uniform fill

• In-line weight control and tablet rejection

• Dust extraction systems

Innovations in Tablet Presses

• Multi-layer tablet presses (for controlled or dual-drug release)

• Containment systems for handling high-potency APIs

• Predictive maintenance using IoT sensors

• Servo-driven compression for high-precision force control

Advantages

• Consistency in weight and content

• Customizable tablet shapes and logos

• High productivity (up to 500,000+ tablets/hour)

• Suitable for pharmaceutical, nutraceutical, and veterinary applications

🧴 Capsule Equipment: Precision in Encapsulation

What Is Capsule Equipment?

Capsule equipment is used to fill, seal, polish, and inspect hard or soft gelatin capsules. Capsules offer several advantages over tablets — such as easier swallowing, faster release, and better API stability.

Major Types of Capsule Equipment

1. Capsule Filling Machines

   • Manual Capsule Fillers

     • Used in small-scale settings or R&D labs.

   • Semi-Automatic Capsule Fillers

     • Combine manual capsule loading with automated powder filling and closing.

   • Automatic Capsule Filling Machines

     • Fully automated systems that fill capsules with powder, granules, pellets, or liquids.

     • Can process thousands of capsules per minute.

2. Capsule Polishing Machines

   • Remove excess powder and enhance the appearance of filled capsules.

3. Capsule Sorting & Inspection Machines

   • Remove empty or defective capsules using weight or visual inspection.

4. Banding/Sealing Machines

   • Used for liquid-filled capsules to prevent leakage and tampering.

Innovations in Capsule Technology

• Micro-dosing capabilities for low-dose drug delivery

• Inert gas flushing for oxygen-sensitive APIs

• Robotic capsule loading/unloading

• Real-time fill weight monitoring

Benefits

• Flexible dosage forms (liquid, powder, granules)

• Reduced cross-contamination risk

• Enhanced product aesthetics

• Ideal for modified-release formulations
