Explore our core high-precision filling and metering machines engineered for maximum operational consistency and strict safety standards.
In modern industrial manufacturing, packaging precision is no longer merely a metric of quality control—it is a critical driver of profitability, regulatory compliance, and brand integrity. The demand for custom OEM/ODM liquid metering machines has escalated globally as industries transition from manual or semi-automated systems to fully integrated, cyber-physical manufacturing systems (Industry 4.0).
From micro-dose vial filling in the biopharmaceutical sector to high-capacity bulk packaging of petrochemical lubricants, modern liquid metering requires precise fluid dynamics engineering. Volumetric accuracy, droplet prevention, laminar flow maintenance, and shear-sensitive handling are the foundational pillars of our structural design. By integrating positive displacement, piston, and Coriolis flow-meter technologies, we ensure your production lines operate with minimal product loss and zero-downtime performance.
Globally, companies faces strict raw material cost increases. Reducing standard deviation in filling volume from 1.5% down to under 0.2% can save tens of thousands of dollars in high-value liquids (such as premium olive oils, active cosmetic serums, or specialized chemicals) over single production cycles. The transition to high-precision servo-controlled liquid metering technology is the most direct pathway to achieving this efficiency.
Every liquid possesses distinct rheological characteristics. Temperature changes, chemical volatility, and viscosity index shifts affect flow behavior. Modern factories require metering machinery designed with dynamic density compensation to adjust operational parameters in real-time, matching variations across product batches.

By utilizing advanced regenerative servo drives, our liquid metering systems recycle deceleration kinetic energy back into internal circuitry, lowering overall power demand. Optimizing the pneumatic control architecture drops pneumatic air requirements by up to 25% across full shifts.
Liquid metering machinery is highly context-dependent. The physical requirements of a system deployed in a chemical facility differ radically from those of a GMP-regulated pharmaceutical environment. Here is how our custom solutions operate in real-world local contexts:
In chemical packaging (e.g. detergents, industrial solvents, aggressive acids), mechanical resilience is essential. Corrosion-resistant polymers, high-density polyethylene structural framing, and specialized Hastelloy components are deployed to ensure long-term durability. Explosion-proof integrations (specifically meeting ATEX or UL Class I Div 1 requirements) are standardized on filling heads, propellant pumps, and seal controllers for aerosol lines.
Cosmetic creams, high-viscosity face pastes, and sterile pharmaceutical capsules require strict sanitary design. Our systems utilize 316L stainless steel, tri-clamp sanitizing connections, and automated CIP (Clean-in-Place) architectures. Rotary piston volumetric pumps or servo-driven peristaltic systems ensure that delicate ingredients remain uncontaminated by external contact, keeping batch integrity fully secure.
Speed and hygiene are the dominant metrics in food-grade water, juice, and sparking beverage operations. Our high-capacity rotary bottling machines are built to withstand high-pressure washes while maintaining filling tolerances within strict metrics. High-viscosity food sauces containing particulates (such as chili seeds or pulp) use specialized dynamic gating to avoid crushing ingredients while metering precise volumetric quantities.
High-viscosity gear lubricants, grease, and brake fluids need powerful positive displacement mechanisms. Subsurface filling techniques are used to prevent foaming, utilizing heavy-duty bottom-up filling nozzles that adjust height dynamically during the metering cycle. The structural integration of mass-flow controllers minimizes temperature-related volume discrepancies across bulk batches.
Our facility in Hebei province leverages the unparalleled structural integration of China's heavy industrial core. Standardized steel processing, specialized precision components fabrication, and state-of-the-art electronics are localized within a 100-kilometer radius. This geographic proximity drastically shortens R&D cycles, enables rapid prototyping, and significantly mitigates the risk of global supply chain blockages.
The global industrial landscape relies heavily on manufacturing resilience. When procuring custom liquid metering lines, buyers balance cost efficiency against structural engineering standards. By centering our production at Hebei Yongli Machine Co., Ltd, we combine premium components with highly efficient, optimized processing.
We source structural pneumatic control units directly from top global brands (such as Festo and SMC) and electrical logic components from leading names (such as Siemens, Omron, and Schneider Electric). By coupling these imported high-precision sub-components with our optimized local structural fabrication, we deliver machines with high structural integrity at a fraction of the cost of European or North American counterparts.
Furthermore, our streamlined factory operations mean that customization work (OEM/ODM) is integrated into our main production flow, ensuring that customized orders do not experience long queue bottlenecks. From engineering sign-off to container loading, our turnaround cycles remain up to 40% faster than typical Western manufacturers.
Procuring capital industrial machinery from a global supplier requires strict regulatory verification.

High-efficiency specialty machinery engineered to handle complex container formats, high-viscosity creams, and demanding industrial sealing specifications.
Direct engineering insights answering critical technical questions regarding fluid displacement systems.
Our standard liquid metering systems utilize high-resolution brushless servo motors coupled with positive displacement gear pumps or precision piston assemblies. Under stabilized pressure and uniform product viscosity conditions, our systems achieve a volumetric precision margin of <0.2%. This high tolerance prevents product overfills, significantly reducing product giveaway across long production runs.
Yes, absolutely. For high-viscosity pastes, ointments, cosmetic creams, and food sauces containing solid particulates (such as tomato pastes or chili oils), we deploy specialized piston filling configurations. These setups utilize rotary valve systems and enlarged fluid pathways, ensuring particulates pass cleanly through without causing mechanical blocks or crushing the product.
For corrosive chemicals, standard stainless steels are insufficient. We manufacture these specific product tracks utilizing high-density plastics (such as PP, PVC, or PTFE) for all liquid-contact surfaces, coupled with specialized Hastelloy or titanium components. Standard structural framing is additionally coated with protective anti-corrosion epoxies to safeguard mechanical integrity.
Bag-on-Valve technology is a highly sanitary packaging choice. The active liquid product is hermetically sealed within a laminated internal bag, completely separated from the propellant gas. This prevents product oxidation, extends overall shelf life, and permits a clean 360-degree spray orientation, which is highly valued in premium pharmaceutical, cosmetic, and olive oil applications.
Our pharmaceutical and food-grade filling lines are designed to integrate seamlessly with standard CIP and SIP (Sterilize-in-Place) infrastructure. The fluid pathways utilize sanitary tri-clamp connections and feature no dead legs or hard-to-reach pockets. This allows sanitizing agents and hot steam to cycle completely through the valves, pumps, and filling nozzles, ensuring clean verification checks between product batches.
