Mascara is widely recognized in the cosmetic industry as one of the most difficult formulations to fill and cap with consistent accuracy. Due to its thixotropic nature, high viscosity, fiber enrichment (for volumizing and lengthening effects), and rapid drying properties, ordinary liquid filling systems inevitably suffer from nozzle clogging, inaccurate volumetric dosing, air bubble entrapment, and unhygienic product leakage.
For cosmetic manufacturing giants and OEM/ODM laboratories, maintaining a reliable, high-speed, and contamination-free packaging line is essential for operational efficiency and brand equity. The SINA EKATO Automatic Rotary Vial Bottle Liquid Filling and Capping Machine has been engineered from the ground up to address these specific paint points. Utilizing advanced rotary indexing and servo-motorized dosing systems, this equipment ensures that every mascara vial—whether designed with complex brush geometries or thick outer sleeves—is processed to perfection without compromising aesthetic styling or chemical integrity.
Understanding the mechanics behind SINA EKATO's rotary filling and capping station reveals why it dominates the high-viscosity beauty sector.
Equipped with highly accurate servo-driven volumetric piston pumps, our machine achieves filling tolerances of ±0.1g. This mechanism eliminates structural shear on mascara fibers, protecting the formulation's performance integrity.
Our multi-station rotary star wheel layout guarantees seamless transit between bottle feeding, air-blowing cleaning, nitrogen purging, filling, wiper insertion, brush insertion, pre-capping, and final torque capping.
Prevents cosmetic cap scratching and deformation. Real-time control over torque limits guarantees hermetic seal integrity, preventing formula dry-out throughout its retail shelf life.
The standard SINA EKATO automatic rotary vial line features high-speed, continuous-motion capabilities capable of producing 40 to 60 units per minute (depending on viscosity profiles). The entire system is built utilizing premium SUS316L stainless steel contact parts to prevent reactions with carbon blacks or organic pigments typical of modern mascaras. An integrated CIP (Clean-in-Place) and SIP (Sterilize-in-Place) protocol is programed within the central Siemens HMI, minimizing downtime between product transitions.

Science and technology are primary productive forces. To achieve zero-fault manufacturing operations, SINA EKATO sources 80% of its critical system components from the world's most renowned mechanical, pneumatical, and electronic suppliers.
By using industry-standard hardware such as Siemens PLC controls, Omron sensors, Schneider electric components, and Festo pneumatics, we guarantee that maintenance, localization, and spare parts sourcing are frictionless for global facilities.
Our commitment to the global community is represented by our design motto, "LET THE WORLD KNOW MADE IN CHINA", delivering high-performance machinery and services. We do not just build machines; we engineer competitive advantages for our partners.
With stable, reliable, precise, and intelligent operation standards, SINA EKATO has earned trust worldwide. Our engineering team closely collaborates with your plant layout coordinators from design phase to commissioning (SAT), ensuring seamless integration of the mascara line with upstream mixers and downstream labeling systems.
SINA EKATO is continuously investing in next-generation cosmetic production technologies, preparing global manufacturers for future challenges.
Future iterations of our filling machines will incorporate real-time feedback loops. Inline viscometers communicate directly with the servo motors to adjust dosing pressure and speed dynamically, preventing under-fills as temperature changes.
By capturing telemetry data from magnetic capping stations, our systems analyze cap threads in real-time, sending automated warnings if variations point to mechanical wear or bottle quality anomalies.
Enabling full vertical integration within ERP/SCADA platforms. This ensures that every run, batch number, capping success rate, and downtime log is securely recorded to comply with modern track-and-trace requirements.
SINA EKATO excels at providing complete, turnkey systems. A mascara filling line does not exist in isolation; its performance depends on upstream and downstream machinery compatibility.
A typical end-to-end mascara production ecosystem designed by SINA EKATO includes:
This integration ensures synchronized line speed, minimizing bottle accumulation and maximizing overall equipment effectiveness (OEE).
Navigating global regulatory frameworks is standard practice for SINA EKATO. Our cosmetic equipment complies with current Good Manufacturing Practices (cGMP), FDA specifications, and European CE directives. We provide a complete documentation package, including Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), and IQ/OQ validation protocols to assist your quality control teams in regulatory audits.
With dedicated international service points and partnerships—including Germany SINAEKATO Group—we deploy experienced commissioning technicians globally, ensuring fast startup times.
Our primary manufacturing hub in Gaoyou, Jiangsu province, utilizes a complete industrial supply chain ecosystem. From local precision casting and high-tolerance CNC machining to specialized surface treatment, we control the production cycle end-to-end.
This vertical integration ensures short delivery times and competitive pricing without sacrificing component quality. This setup enables us to withstand global raw material shortages and maintain manufacturing schedules.
When procurement departments assess new machinery investments, several factors drive their decision. SINA EKATO addresses these requirements systematically:
We reduce lifetime maintenance costs by sourcing 80% of parts from global brands. This enables local replacement without long customs delays, minimizing costly line stoppages.
Modern product lines must support multiple packaging profiles. Our changeover kits allow line adjustments for different vial diameters, lengths, and cap profiles in under 30 minutes, without requiring specialized tools.
Low physical footprint, accessible maintenance access points, and clean, multi-language HMI control menus help reduce training overhead and operational errors.
