Automatic Machine for gluing and sealing hard capsules

The NSF-800 Automatic Sealing Machine is engineered to provide a reliable, hermetic, and high-speed bond between the cap and the body of hard capsules. This equipment is a critical asset for pharmaceutical and biotech manufacturers producing oil-based, aqueous, or suspension-filled capsules, as well as dry powder forms. By applying a precise gelatin-based "band" or seal, the machine eliminates the risk of leakage, prevents oxygen degradation of sensitive ingredients, and enhances the visual professional appeal of the final product.

The NSF-800 handles the entire process automatically—from capsule feeding and orientation to the application of the adhesive and final drying. It is fully compatible with capsule sizes ranging from 00# to 4# and supports both traditional gelatin and vegetarian (HPMC) shells.

Key Features and Operational Advantages

• Versatility: Specifically designed for liquid-fill applications (oils and suspensions) where a hermetic seal is mandatory to prevent leakage.

• Dual Gluing Modes: Capable of working with both water-soluble and non-soluble adhesive agents to suit different formulation requirements.

• Thermal Precision: Features an integrated heating system to maintain the adhesive solution at a stable temperature between 30–40 °C, ensuring consistent viscosity and bonding strength.

• GMP Compliance: Built with pharmaceutical-grade stainless steel, the machine features a streamlined design with no "dead zones," making it easy to sanitize and maintain.

• Seamless Integration: Can operate as a standalone unit or be integrated into a continuous production line immediately following a capsule filling station.

Benefits of the NSF-800 System

• Enhanced Product Stability: Protects the contents from oxidation and external contamination, significantly increasing shelf life.

• Minimal Product Waste: High-precision alignment and dosing of the sealing agent result in an exceptionally low reject rate.

• Labor Efficiency: Full automation reduces the need for manual intervention, lowering operational costs and human-error risks.

• Tamper Evidence: The sealing band provides a clear indication of product integrity, which is vital for consumer safety and regulatory compliance.
