Explore our state-of-the-art system components engineered for extreme efficiency and compliance.
The manufacturing of modern cosmetics requires an unparalleled level of fluid handling precision. Among the most complex formulations is mascara, a highly viscous, thixotropic material containing film-forming agents, volatile solvents, waxes, and dense color pigments. Traditional gravity-fed or standard positive pressure piston filling configurations often fail to handle mascara effectively, leading to issues like product stringing, nozzle build-up, and air pocket trapping within the narrow neck of mascara brush tubes.
Our CE Certified Automatic Cosmetic Mascara Brush Tube Bottle Negative Pressure Filling Machine utilizes advanced vacuum-assisted fluid dynamics to resolve these challenges. By drawing air out of the container before and during the filling process, the negative pressure system ensures that the high-viscosity product seamlessly flows to the bottom of the container, eliminating air bubbles and guaranteeing a clean fill without neck contamination. This mechanism not only accelerates cycle times but also maintains a strict dosage tolerance of ±0.1g, essential for high-end luxury cosmetic brands.
Rooted in innovation, our systems utilize premium components from global leading brands to guarantee longevity and international safety compliance.
Over 80% of our machinery components are sourced from globally recognized suppliers, ensuring outstanding reliability, high performance, and easily accessible replacement parts worldwide.
Our manufacturing processes comply with rigorous European CE safety, health, and environmental protection standards, providing worry-free operation and seamless imports into high-standard markets.
With over 30 years of machinery and formulation experience, SINA EKATO delivers optimized solutions that bridge the gap between chemical properties and advanced mechanical output.

Global cosmetics brands are increasingly seeking Chinese factories to build their custom packaging production lines. China's industrial clusters for cosmetic machinery, particularly in provinces like Jiangsu and Guangdong, provide unmatched integration speed, highly skilled engineers, and high-quality raw materials like SUS316L surgical-grade stainless steel.
By keeping manufacturing operations concentrated under the SINA EKATO Headquarter in Gaoyou City, we utilize advanced CNC milling, strict quality control procedures, and comprehensive functional stress tests before any machinery is shipped. This approach reduces overall lead times and ensures that local cosmetic companies can easily scale their operations from semi-automatic test batches to fully integrated, multi-head negative pressure automatic production lines.
A timeline of innovation, engineering excellence, and international expansion over the past three decades.
Mascara brush and tube bottle configurations vary significantly across regional cosmetic markets. In the North American and European sectors, user preferences lean toward complex brush shapes (e.g., asymmetrical plastic or dense fiber bristles) that retain a high volume of formulation. In East Asian markets, smaller, precision-oriented brushes for lengthening and lifting are more popular.
Our negative pressure filling system adapts to these variations. By using a quick-change container holder and a modular nozzle system, the machine adjusts to different container volumes, tube materials, and wiper geometries in minutes. Whether you are packaging glass-finish mascara tubes, PET/PETG plastic bottles, or eco-friendly aluminum containers, the negative pressure filling technology prevents friction-induced damage and ensures consistent results.
Additionally, the machine integrates seamlessly with upstream cosmetic preparation equipment, such as vacuum emulsifying mixers and storage tanks, forming a continuous, touchless production line that meets strict international cosmetic standards.
Over the years, SINA EKATO's commitment to reliability and innovation has earned the trust of global cosmetic companies. We focus on providing high-performance machinery backed by dedicated technical support and after-sales service.
Our support system includes on-site installation, operational training, process optimization consultations, and spare parts supply.
