Understanding how fluid mechanics, material behaviors, and precision engineering converge to deliver repeatable, clean, and accurate packaging for non-Newtonian fluids.
Highly viscous products (ranging from 10,000 cPs to over 1,000,000 cPs) such as ointments, heavy creams, lipsticks, and sealants exhibit non-Newtonian behaviors. Under shear stress, their viscosity changes dramatically. SINA EKATO's filling architectures utilize state-of-the-art servo-driven piston assemblies that accurately profile velocity to prevent cavitation, minimize shearing forces, and preserve product integrity.
Filling thick pastes often leads to "tailing" or stringing at the nozzle tip, causing container contamination. We solve this by integrating custom dynamic cut-off nozzles with positive shut-off pins and precise vacuum pull-back functions. This configuration draws back excess product instantly at the cycle's end, ensuring immaculate seals and consistent tare weights.
Viscous materials readily trap air bubbles, which skews volumetric measurement and accelerates oxidation. Our solutions feature bottom-up filling sequences, where nozzles submerge to the base of the container and lift in tandem with the rising liquid levels. Combined with SINA EKATO vacuum homogenization pre-treatment, we guarantee bubble-free products.
SINAEKATO, established in 1992, is one of China's leading machinery brands. Over the course of three decades, we have developed a deeply respected technological footprint. Our specialization spans across Vacuum Emulsifying Mixers, Liquid-washing Homogenizer Mixers, Perfume Chiller Production Lines, Toothpaste Production Mixers, Fully-automatic and Semi-automatic Filling Machines, Storage Tanks, Reverse Osmosis (RO) Water Treatment Series, and automated Labeling and Packing systems.
We provide comprehensive, one-stop engineering solutions designed for the skincare, cosmetic, pharmaceutical, food, and fine chemical industries. Through our global network, we enable organizations to transition from raw ingredient mixing to final retail-ready packaging seamlessly.
Science and Technology are the primary productive forces; they are also the core competitiveness of enterprises. Continuously strengthening the research, development, and innovation of core technologies, we constantly strive for excellence. Our advanced production equipment, strict quality management systems, and precise production testing processes ensure the excellent performance of each system delivered.
On the other hand, our longstanding commitment to the global social framework drives us to fulfill the slogan "LET THE WORLD KNOW MADE IN CHINA" by providing high-performance machinery and services. We actively invest in communities, exercising imagination, donating time, and sharing technical expertise to contribute to overall industrial progress.
To ensure unparalleled reliability, 80% of the main components of our machinery are sourced from world-renowned suppliers (such as Siemens, Schneider, Omron, Festo, and SMC). Through long-term cooperation, we have accumulated valuable design and integration experience, enabling us to provide our clients with exceptionally high-quality machines and effective long-term operational guarantees.
SINA EKATO’s dedication and technological capabilities are globally recognized. Stable, Reliable, Precise, and Intelligent are the baseline performance metrics we establish for every system we design. Choosing SINA EKATO means selecting world-class technical support and robust, lifetime after-sales services.
We work closely with global cosmetic, pharmaceutical, and chemical manufacturers, aligning our development cycles with their operational scaling. Step by step, we innovate for the future of automated packaging.

How our filling machinery meets the complex regulatory landscapes across North America, Europe, Asia-Pacific, and emerging markets.
For pharmaceutical and cosmetic operations, preventing cross-contamination is critical. SINA EKATO machines are manufactured using SUS316L stainless steel for all contact components. Every internal surface is electropolished to a roughness rating of Ra < 0.4μm, preventing bacterial accumulation and ensuring thorough Clean-in-Place (CIP) performance.
High-viscosity liquids containing volatile solvents, alcohol bases, or petrochemical compounds require specialized explosion-proof setups. SINA EKATO designs customized ATEX-certified systems incorporating air-purged control cabinets, explosion-proof servo motors, and grounded paths to dissipate static charges safely.
We configure electrical layouts to match our customers' local codes. Whether compliance demands CE markings for the European Union, UL/CSA certifications for the North American market, or specific electrical enclosures for Australia, our engineering division handles drawing submissions, validation documentation, and pre-shipping factory tests.
Examining customized mechanical integrations across distinct commercial settings, verifying precision, clean execution, and high production speeds.
For cosmetic formulations that require precision temperature control to remain fluid, our machines incorporate double-jacketed heated hoppers with internal scraping agitators. Our servo systems maintain temperatures up to 85°C, ensuring consistent material flow from the hopper through the dosing cylinder into delicate containers.
Operating inside ISO Class 5 and 7 cleanrooms, these custom systems utilize sterile rotary lobe pumps or positive displacement pistons. By implementing clean, hermetic product paths and quick-clamp connections, we allow operators to tear down, clean, and sterilize components with minimal downtime.
Filling dense, abrasive industrial pastes (like silicone sealants, pigments, and metallic inks) requires specialized components to resist wear. We use hardened alloy components and ceramic-lined cylinders to handle abrasive particulates, preventing early wear and maintaining dosing accuracy over millions of cycles.
A look into how smart automation, IoT diagnostics, and advanced fluid simulation shape the next generation of industrial packaging machinery.
By integrating smart sensor arrays across all motor drives, pressure lines, and pneumatic actuators, our next-gen systems monitor real-time thermal profiles and pressure drops. The central PLC analyzes this data to predict seal wear or nozzle blockages before they cause line stoppages, automatically notifying plant operators.
AI controls adjust stroke speeds and nozzle depth dynamically based on batch viscosity variations. If raw ingredients show higher viscosity than the previous batch, the machine adjusts the suction stroke duration and nozzle return speeds to prevent air pockets without reducing overall throughput.
Water and product conservation are critical metrics for modern manufacturers. Our future product pipeline includes smart CIP systems that use air-purge technology to retrieve product left in the pipelines before cleaning. These systems use dynamic spray balls to reduce water and detergent use by up to 40% compared to traditional cleaning setups.
