Explore our core industrial grade processing, homogenization, and liquid/paste filling equipment configured for premium cosmetic manufacturers.
Mascara is widely recognized in the cosmetic chemistry sector as one of the most challenging substances to fill. It features high thixotropy, meaning it liquefies when agitated but returns to a highly viscous, gel-like state when left at rest. Formulations are heavily packed with carbon black, iron oxide pigments, structural waxes (such as beeswax, carnauba, and candelilla), and quick-drying film formers. If handled using inadequate fluid-delivery systems, phase separation, air entrapment, or severe nozzle clogging occur.
Our semi-automatic cosmetic mascara filling machinery employs a precise Volumetric Piston Dosing system coupled with temperature-controlled hoppers. By maintaining the mascara at a highly regulated, consistent temperature (generally between 40°C and 55°C), the waxes remain in a fluid state without altering their chemical properties. The integrated paddle mixing system prevents pigment sedimentation, ensuring that every cycle outputs identical density, color consistency, and volume.
“Precision in mascara filling is not merely about volume; it is about managing viscosity transitions under dynamic temperature parameters to eliminate micro-voids inside the cartridge.”
How SINAEKATO semi-automatic platforms ensure batch-to-batch repeatability and absolute dosing compliance for industrial scale cosmetic operations.
Features zero-drip pneumatic cut-off nozzles engineered specifically for viscous gels. It prevents tailing and stringing of mascara formulas onto bottle necks, ensuring sanitary runs and decreasing waste material losses.
Equipped with SUS316L double-jacketed heating vessels with integrated water circulation and continuous anchor agitation, designed to prevent cold spots and protect sensitive ingredients from burning.
High-precision physical volume limiters paired with digital PLC controls allow operators to adjust dosing capacity down to ±0.1ml tolerances, conforming strictly to global weight-label laws.

Our longstanding commitment to communities in which SINA EKATO operates reflects our core belief: that no individual or cooperation can be a good citizen without getting actively involved—exercising imagination, donating time and skills, and providing financial support.
We aim to develop "LET THE WORLD KNOW MADE IN CHINA" by providing high-performance machinery and services. Our global supply partnerships ensure robust system integration across all product lines.
80% of the main parts of our machines are provided by the world’s most famous suppliers. Through long-term cooperation and technical exchange with them, we have accumulated valuable experience to provide customers with high-quality machines and effective guarantees.
Why the world's leading beauty conglomerates source their mechanical lines from SINAEKATO in Gaoyou City and Guangzhou.
Located in the heart of Jiangsu & Guangdong chemical machinery production hubs, we utilize a local network of precision CNC machinists, raw steel mills, and electrical engineering firms. This reduces component lead times by up to 45% compared to European competitors.
While mechanical assembly and steel welding are completed in-house, the critical electronic and pneumatic control components are sourced directly from global leaders (Siemens PLC, SMC Pneumatics, Omron Sensors, Schneider Electric) for reliable service globally.
Every semi-auto mascara filler undergoes a mandatory 72-hour continuous cycling test with high-viscosity simulated fluids prior to shipment. Customers receive full video trials and dimensional reports before freight dispatch.

Our semi-automatic filling machines comply with the EN 60204-1 safety standards. Controls utilize low-voltage 24V DC circuitry, ensuring protection for operators during high-moisture production cycles.
Constructed entirely of SUS304 shell structures and mirror-polished SUS316L internal product-contact parts (Ra < 0.4µm), our equipment facilitates complete Clean-In-Place (CIP) procedures to meet strict hygienic regulations.
For formulas utilizing volatile silicone carriers, organic solvents, or alcohol bases, SINAEKATO installs pneumatic drives and explosion-resistant enclosures to secure hazardous industrial environments.
Tailoring modular machinery setups to specific operational scales, cosmetic formulations, and manufacturing environments.
For emerging beauty start-ups or pilot R&D divisions of multinational brands, purchasing an automatic packaging line is often cost-prohibitive. The semi-automatic mascara filling machine fits these needs perfectly, requiring minimal space and offering quick changeover options for diverse cosmetic bottles.
Certain heavy formulas, such as clay mask treatments, brow pomades, and thick wax-based mascaras, require constant heating to prevent curing in the dispensing nozzle. Our temperature-regulated jacketed hoppers and mixers keep the formulations warm and flowing, preventing line blockages.
For OEM/ODM contractors processing short runs of different colors (black, brown, blue, clear glosses) on the same day, cleaning times must be minimized. The modular design of our volumetric piston pumps allows for fast breakdown, cleaning, and sanitizing inside the cleanroom.
Direct technical responses addressing the primary compliance, mechanical, and logistical questions raised by global procurement officers.
By utilizing highly accurate volumetric piston cylinders linked with mechanical dial limiters, our machinery consistently hits tolerances within ±0.5% to ±1% of the target volume. This accuracy holds true even when processing dense, non-Newtonian formulas like lengthening mascaras containing synthetic microfibers.
Yes. The internal flow path, rotary valve structure, and fill nozzles are designed to prevent fiber shearing or accumulation. We recommend installing our dynamic ribbon impeller within the hopper to keep fibers evenly distributed throughout the batch.
We supply machinery customized for global voltages: 110V 60Hz single-phase for North American markets, 220V 50Hz for Southeast Asia/China, and 380V 50Hz three-phase configurations for European industrial standards. All motors and heating controls are adapted to the customer's specified facility power grids.
Because our pumps utilize tri-clamp sanitary fittings, an operator can disassemble the primary piston, rotary valve, feed pipe, and nozzle without tools in under 15 minutes. A complete washdown, sanitation run, and reassembly can be executed within 30 to 45 minutes.
Yes, our semi-automatic machinery features a PLC control board with dual modes: a foot pedal mode for manual operation and an external I/O contact mode. This allows you to integrate the filler with automated conveyor lines and capping systems in the future.
With over 30 years of export experience spanning 55 countries, we maintain an international service department. We offer step-by-step video installation guides, online diagnostics via PLC ethernet modules, and dispatch field technicians for on-site commissioning and training.
