6-Lane Nespresso Capsule Filling Sealing & Cartoning Line | 300 CPM / 18,000 Capsules Per Hour with KUKA Robot & Mettler Toledo Checkweigher
Fully Automatic Turnkey Solution for 30-Capsule Boxes (Up to 3 Layers) — Nitrogen Flushing, Residual Oxygen <1%
The SC-6 Six-Lane Nespresso Capsule Production Line is a fully integrated, turnkey solution designed for high-speed, precision manufacturing of Nespresso-compatible coffee capsules. With a rated capacity of 300 capsules per minute (18,000 capsules per hour), this line combines six-lane parallel filling and sealing with automatic top-load cartoning, KUKA robotic pick-and-place, and Mettler Toledo inline checkweighing.
Engineered for scalability and consistency, the system handles the complete production flow: from capsule denesting and servo-driven powder filling, through nitrogen-flushed sealing with residual oxygen below 1%, to automated cartoning of 30 capsules per box in up to 3 layers, and final 100% weight verification before discharge.
Built with food-grade SUS304 stainless steel and CE/ISO9001-compliant construction, this line is suited for private-label coffee brands, contract manufacturers, and capsule factories requiring reliable 24/7 operation with minimal manual intervention.

Vertical servo-driven capsule loading system with dual capsule storage capacity (approximately 1-hour operation). Empty capsules are automatically denested and fed into the six-lane mold at high speed. Integrated empty-capsule detection ensures “no capsule, no filling” logic, preventing waste and misfilling. -9
Six independent servo motor-driven auger fillers deliver precise dosing of ground coffee powder. The filling weight is adjustable via HMI, with accuracy of ±0.15g based on 10,000-sample average. The system supports quick changeover for different capsule formats and powder types (coffee, tea, soluble powders).
A full-process nitrogen protection tunnel runs from the capsule denesting station through to the sealing station. This MAP (Modified Atmosphere Packaging) approach reduces residual oxygen to below 1%, significantly extending the shelf life and preserving the aroma of ground coffee.
The machine uses rolled aluminum foil (rather than precut lids) for cost efficiency and reduced material waste. A precision cutting module punches individual lids, which are then heat-sealed onto the capsule rims. Consistent sealing temperature and pressure ensure a zero-fault seal ratio.
After the primary sealing, a secondary heat sealing station reinforces the lid bond for maximum seal integrity and leak prevention. This dual-sealing approach is critical for maintaining the <1% residual oxygen specification and ensuring capsules withstand handling during cartoning.
A swing manipulator arm gently catches finished capsules from the six-lane mold and transfers them to a discharge conveyor (up to 1200mm extension). The arm is designed to avoid capsule damage during the high-speed transfer, feeding the downstream cartoning system.
A dedicated top-loading cartoner receives sorted capsules from the discharge conveyor and loads them vertically into paperboard boxes. The system is configured for 30 capsules per box, arranged in up to 3 layers. Top-loading design accommodates rigid Nespresso capsules without crushing.
Automatic box erecting and forming station that opens flat papercard blanks into three-dimensional boxes ready for capsule loading. The system synchronizes with the cartoner to maintain continuous flow at 18,000 capsules/hour output.
A KUKA industrial robot performs high-speed pick-and-place of filled capsules into the carton boxes. This robotic solution replaces conventional drop-loading or pneumatic systems, offering superior flexibility for different box configurations and gentle handling of aluminum capsules. The robot picks capsules in groups and places them layer-by-layer into each box.
A Nordon hot-melt glue sprayer applies precise adhesive patterns to the box flaps before sealing. The Meler system is known for consistent glue application, low maintenance, and compatibility with food-grade adhesives. This ensures clean, secure box closure without excessive glue waste.
After glue application, the box flaps are folded and compressed to form a sealed carton. The sealing station integrates with the cartoner’s main drive for synchronized operation, ensuring each 30-capsule box is properly closed before discharge to the checkweigher.
A Mettler Toledo online checkweigher performs 100% inline weight verification of each finished carton box. The system is set to verify the target weight of 30 capsules per box. Any underfilled or overfilled boxes are automatically rejected before palletizing, ensuring retail compliance and product integrity.
