High-efficiency process equipment engineered for cleanroom operations and strict compliance standards.
In the rapidly evolving global personal care industry, the automated packaging of high-viscosity and sensitive formulas requires sophisticated engineering. The Automatic Mascara & Lip Balm Aluminum-Plastic Soft Tube Filling and Sealing Machine sits at the intersection of micro-precision filling mechanics and advanced hermetic seal technologies. As cosmetics shift toward organic formulations with fewer synthetic stabilizers, packaging machines must prevent oxidation, ensure tight contamination controls, and manage varied structural tube substrates.
This industrial whitepaper examines the integration profiles, technological architectures, supply chains, and regulatory alignments essential for manufacturers seeking optimized throughput. By utilizing modern thermodynamic sealing principles—including high-frequency ultrasonic and localized hot-jaw systems—today's packaging lines minimize operational reject rates to under 0.05%, ensuring complete structural integrity across diverse materials like PE, laminated plastic, and aluminum.
Decoupling the electromechanical subsystems that govern high-speed tube filling operations.
Utilizing high-accuracy positive displacement rotary valve pumps and servo-driven piston fills. This ensures high-viscosity materials (e.g., thixotropic mascara emulsions and thermal-reversible hot-poured lip balms) are dosed with a precision tolerance of ±0.1g. Built-in suck-back nozzles prevent post-dosing drips that can compromise seal integrity.
Adapting variable sealing modes for diverse tube chemistry. Plastic and composite laminated tubes utilize internal hot air systems coupled with localized water-cooled clamping jaws. Pure aluminum tubes utilize multi-fold mechanical crimping assemblies, enabling flat, double-fold, or saddle-fold closing without tearing metal barriers.
An integrated photoelectric sensor array detects precise registration marks on flexible tubes. This system automatically rotates each tube to ensure the printed design lines up correctly before sealing. Completed tubes undergo an inline visual check, and any defective products are rejected without halting production.
How regional manufacturers adapt SINA EKATO machinery to distinct operational standards.
In highly regulated environments, system designs must align with FDA, GMP, and CE Annex 15 standards. SINAEKATO machines feature 316L stainless steel contact parts, surface finishes below 0.4µm Ra, and full clean-in-place (CIP) capabilities. The integration of explosion-proof components (ATEX) supports formulations containing volatile organic compounds (VOCs).
Operating in tropical regions presents challenges with relative humidity and condensation. SINA EKATO builds pneumatic air preparation units and moisture filtration systems directly into the frame. Condensate-resistant electrical panels and gold-plated sensor pins ensure reliable operation, preventing corrosion-induced failures in warm climates.
Cosmetic contract packers need to shift between mascara, lip balm, sunscreen, and foundation tubes multiple times per shift. SINAEKATO addresses this with a modular, tool-free rotary puck replacement system. This allows lines to be converted for different tube diameters (10mm to 50mm) in under 20 minutes, maximizing overall equipment effectiveness (OEE).
Science and Technology are the primary productive forces, they are also the core competitiveness of enterprises. Continuously strengthen the research and development and innovation of core technologies, constantly strive for excellence, advanced production equipment, strict quality management, precise production testing process to ensure the excellent performance of each product.
On the other hand, a longstanding commitment to the social in which SINA EKATO aims to develop “LET THE WORLD KNOW MADE IN CHINA” to provide high-performance machinery and service. Also a longstanding commitment to communities in which it operates reflects belief that no individual or cooperation can be good citizen without getting actively involved - exercising imagination, donating time and skills and providing financial support.
80% of the main parts of our machines are provided by world’s famous suppliers (such as Siemens, Omron, Festo, and Schneider). During long-term cooperation and exchange with them, we have accumulated much valuable experience, so that we can provide customer with high quality machines and more effective guarantee.
Located in Gaoyou City, Jiangsu Province, and supported by a sales and service center in Guangzhou, SINAEKATO leverages one of the world's most dense light industrial machinery clusters. This proximity ensures quick turnaround times for specialized components, cast steel structures, and custom-molded parts.
By integrating international components—like Japanese Omron sensors, German Festo pneumatics, and Siemens PLCs—with local precision machining, SINAEKATO balance cost and performance. This approach provides global buyers with industrial-grade machinery at competitive factory prices, backed by responsive engineering support.
Tracking over three decades of engineering excellence and industrial evolution.
Next-generation packaging solutions designed for automated cosmetics lines.
Future platforms will feature IoT integration, leveraging sensors to monitor sealing pressure, temperature, and cylinder velocities in real time. This data is fed into a cloud-based dashboard for predictive maintenance, alerting operators to swap heating elements or seals before failures occur, reducing unscheduled downtime.
As cosmetics brands shift toward sustainable packaging like PCR (Post-Consumer Recycled) plastics, plant-based starches, and thin-walled aluminum, our sealing jaws are engineered with adaptive thermal profiles. These systems prevent burn-through on delicate, heat-sensitive biomaterials while maintaining a reliable hermetic seal.
SINAEKATO plans to build direct mechanical interfaces linking soft tube closing machines with cartooning systems, shrink wrappers, and case packagers. Creating unified control architectures simplifies line speed sync, reducing manual transfers and product handling damage.

Technical answers regarding tube filling, sealing, and customization.
Hot-air sealing heats the inner walls of plastic or laminated tubes using localized hot air before clamping them with cold jaws. Ultrasonic sealing uses high-frequency vibrations to generate friction heat directly within the polymer layer. Ultrasonic systems can seal through minor product contaminants (like oils or paste residue), while hot-air sealing is a cost-effective, high-speed solution for clean filling environments.
To prevent premature solidifying of lip balms, we offer double-jacketed heated hoppers with variable-speed anchor agitators. For mascara, we utilize precise servo-controlled piston pumps to manage shear-thinning viscosities, preventing air pockets and ensuring consistent weight dosing.
Yes, our machines can be configured as hybrid units. While the filling pump remains the same, the sealing station can feature quick-change modules. Operators can swap the hot-air heating nozzles and sealing jaws for mechanical fold-crimping assemblies to run aluminum tubes on the same machine.
We provide a complete documentation package, including Material Test Certificates (for product-contacting 316L parts), electrical schematics, CE conformity certificates, and IQ/OQ validation protocols. This documentation helps support compliance checks and internal quality audits.
