The 0.5-5L lubricant filling line is a fully automatic packaging system designed for filling, capping, labeling, and palletizing bottles across all sizes within the 0.5-5L range. Such versatility provides an ideal solution for manufacturers handling multiple product varieties and frequently changing bottle specifications.
Developed for OEM factories and general-purpose production, this versatile filling line enables efficient automation while significantly improving output and reducing equipment investment. It meets the production needs of industries that require flexible configuration and consistent accuracy in packaging performance.
Taking lubricant packaging as an example, the line integrates a complete set of equipment required for the process from filling and capping to labeling and final palletizing. The same production line can also be applied to other types of liquid materials with similar viscosity and packaging requirements.
Designed to enhance productivity and simplify packaging operations, this universal filling line allows manufacturers to handle diverse production demands with one efficient, cost-effective solution.


The bottle-feeding conveyor is equipped with a wide conveyor belt, frequency converter, motor, and bottle-blocking sensor. Empty bottles are manually placed on the belt and automatically conveyed into the production line for further processing. This configuration keeps bottle transfer steady while reducing manual handling.

By inflating each bottle and monitoring internal pressure changes, the leak tester detects even the smallest air leaks. If a defect or pinhole is detected, the testing system automatically rejects the faulty bottle, preventing defective products from reaching the market.

This labeling system applies front and back labels automatically and includes a vision inspection unit that photographs each labeled bottle to check alignment and surface condition. Any bottles with misaligned or wrinkled labels are automatically detected and rejected. Dual cameras and a computer system ensure fast, accurate label inspection for consistent presentation.

Using twelve synchronized gear pumps, this liquid filling machine achieves accurate and high-speed filling for 0.5–5L lubricant bottles. It can be fitted with an optional storage tank and features a touchscreen interface, PLC control, servo-driven operation, and automatic CIP cleaning. The entire filling machine is made of stainless steel (SUS304) for durability and hygiene.

The servo capping machine features a robotic arm for cap placement and tightening, accommodating large height differences among bottles from 0.5L to 5L. It uses a fixed cap-picking position and adjustable guide rails to ensure quick changeovers and compatibility with various cap sizes. Two capping units are installed to match the line’s total production capacity.

The checkweigher automatically verifies bottle weight and rejects any that fall outside the required standards. Bottle-clamping conveyors on both sides keep each container stable without tipping during transfer.

Designed to seal plastic or glass bottles with aluminum foil, this machine ensures leak-proof closure and extended shelf life. It meets general sealing requirements for a wide range of containers.

After induction sealing, bottles pass through an infrared inspection station. A thermal imaging camera captures the heat signature of each sealed cap, and the image processing system analyzes temperature distribution to determine seal integrity. Bottles with missing foils, loose caps, or incomplete seals are automatically detected and rejected, ensuring only perfectly sealed products continue down the line.

The thermal inkjet printer marks each bottle with production date, batch number, and expiry date. It supports both downward and side printing orientations and offers multiple ink colors for flexible printing options.

This automatic case packer arranges bottles and loads them into cartons using grippers or suction cups. Depending on output requirements, multiple grippers can be configured for higher packing efficiency.

The case erector automatically opens folded cartons, applies hot-melt adhesive, seals the bottom, and delivers the formed cartons to the next station. It provides fast, consistent, and reliable case forming performance.

The case sealer uses hot-melt adhesive to close and seal cartons securely, ensuring neat packaging and long-term product protection. The sealed cartons are then transferred to the next process for inspection or palletizing.

The thermal inkjet printer marks cartons with essential production data, including date, batch number, and expiry information. It supports downward and side printing, offering multiple ink color options for clear, durable markings.

The palletizer automatically stacks cartons onto pallets in multiple layers, replacing manual handling and improving efficiency. Its stacking speed and configuration can be adjusted according to carton size and production requirements.
