Pioneering the Future of Automated Liquid Packaging
Decades of manufacturing excellence combined with cutting-edge robotic automation systems.
Over 30 Years of Engineering Excellence
Ludyway is one of the largest and most respected packaging machine manufacturers in China, specializing in advanced packaging equipment and turnkey production solutions for the food, pharmaceutical, and health industries. From our modern 20,000㎡ manufacturing facility, we design and construct high-performance machinery that handles everything from low-viscosity liquids to highly dense pastes.
Our commitment to continuous research and development has allowed us to deliver over 50 intelligent packaging machine models to customers in more than 100 countries. By integrating smart PLC systems, servo-driven dosing pumps, and robust mechanical structures, we help global enterprises streamline their operations, reduce product waste, and achieve unparalleled efficiency.
Advanced Liquid Dosing & Sealing Systems
Precision-engineered components designed to handle products of all viscosities under strict sanitary standards.
Viscosity Management
Whether packing thin liquids like essential oils or thick, high-viscosity pastes like energy gels and peanut butter, our machines feature custom-configured piston pumps, rotary pumps, and heating hoppers to ensure smooth, continuous product flow.
Hygienic Design & CIP
Engineered with SUS304 and SUS316L stainless steel contact parts, our systems support standard Clean-in-Place (CIP) integration. Smooth welding and sanitary clamp connections allow quick disassembling and thorough cleaning to prevent contamination.
High-Precision Multi-Lane Filling
Our multi-lane sachet and stick pack lines employ independent lane servo dosing controls. This ensures that every single lane performs with high volumetric accuracy (±1% tolerance), reducing product giveaway and maximizing profit margins.
Advanced Sealing Integrity
Equipped with intelligent temperature controllers and customized sealing jaws, our machines produce leak-proof 3-side, 4-side, or back-seal stick packs. We eliminate micro-leaks even when packing aggressive chemical solvents or cosmetic oils.
Smart PLC & HMI Controls
Featuring industry-standard PLC systems (such as Siemens or Allen-Bradley) paired with responsive color touchscreens, operators can easily adjust bag lengths, filling volumes, and sealing temperatures on-the-fly without mechanical changes.
Gas Flushing & Safety
To extend the shelf life of sensitive liquid foods and pharmaceutical formulas, we integrate nitrogen gas flushing systems. Interlocked safety guards and automatic alarm systems ensure absolute operator safety and machine protection.

We match the ideal filling technology to your product characteristics to ensure maximum packaging speed and accuracy.
| Filling Pump Type | Best Suited Viscosity | Typical Applications | Accuracy Rating | Key Engineering Benefit |
|---|---|---|---|---|
| Piston Pump (Pneumatic/Servo) | Medium to High Viscosity | Ketchup, honey, face wash, cosmetic creams, gel packets | ± 0.5% to 1.0% | Excellent volumetric dosing precision; handles chunky/pulpy liquids smoothly. |
| Rotary Lobe Pump | Extremely High Viscosity | Peanut butter, heavy grease, thick industrial adhesives | ± 1.0% | Continuous positive displacement; prevents shearing of sensitive formulations. |
| Flow Meter (Magnetic/Mass) | Low to Medium Viscosity | Water, juices, essential oils, liquid fertilizers, solvents | ± 0.2% | Ultra-precise, non-contact measurement; extremely easy to clean and sanitize. |
| Peristaltic Pump | Low Viscosity (Free Flowing) | Pharmaceutical serums, oral liquids, diagnostic reagents | ± 0.5% | Zero cross-contamination risk; product only contacts the sterile tubing. |
