Advanced machinery designed for high-performance industrial manufacturing.
In the contemporary industrial era, the demand for precision-engineered liquid packaging has surged. Negative pressure filling (vacuum filling) has emerged as the gold standard for low-viscosity liquids, particularly in the perfume and cosmetic sectors. Unlike gravity filling, negative pressure systems ensure a uniform liquid level across all containers, regardless of glass thickness or internal volume variations.
Globally, the market is shifting toward "Zero-Drip" and "Air-Free" environments to maintain product purity. As a leading manufacturer, SINAEKATO integrates these macro-industrial requirements into every machine, ensuring that sensitive formulations—from high-end fragrances to pharmaceutical reagents—are handled without contamination or oxidation.
Our commitment to E-E-A-T principles ensures unparalleled reliability in every unit.

Successful Project Deliveries
The next decade of negative pressure filling is defined by Industry 4.0 integration. We are moving beyond simple pneumatic control toward AI-driven sensor arrays that monitor liquid flow in real-time. Our technical roadmap focuses on:
From initial communication to sea-ready wooden packing.
Proving our reliability across diverse regulatory environments.
Addressing the technical concerns of industry professionals.
Low-viscosity liquids such as perfume, toner, distilled water, and alcohol-based reagents are ideal. The vacuum ensures no dripping and a perfect fill level even in irregular containers.
Our negative pressure nozzles utilize a specialized return-flow design that sucks back excess air and foam, ensuring the liquid settles instantly without bubbles.
With 316L stainless steel construction and high-grade PLC components, our machines are built for a service life of 15-20 years with proper maintenance.
