Grease Filling Machine——High-Viscosity Lubrication Product Filling System
Grease products present one of the most demanding challenges in industrial filling technology. Unlike liquid lubricants, grease is semi-solid, highly viscous, and often formulated with thickening agents such as lithium, calcium, or complex soaps. Its flow behavior changes significantly under pressure and temperature, which makes stable dosing and clean filling more difficult than standard oil or chemical products.
The Grease Filling Machine developed by MIC Machinery is engineered for precise handling of high-viscosity lubrication materials used in automotive, mechanical, and industrial maintenance applications. It is widely applied in grease manufacturing plants, bearing lubricant factories, and industrial chemical packaging facilities where accuracy, pressure stability, and long-cycle reliability are essential.
The system is designed to maintain consistent volume output even when grease resistance changes during continuous operation, ensuring stable filling quality across different container types and production speeds.

Working Process
The grease filling process begins with material preparation in a mixing or holding tank where the grease is homogenized to ensure uniform texture. Many grease formulations require continuous slow mixing to prevent separation of base oil and thickening agents.
Once stabilized, the grease is transferred into a high-pressure buffer hopper that feeds the filling system. In heated configurations, the hopper maintains a controlled temperature to reduce viscosity and improve flow consistency.
Containers are automatically transported to the filling station and positioned under the nozzles using sensor-based alignment. Once correctly positioned, the piston or servo system activates and draws a precise volume of grease from the hopper. The material is then pushed into the container under controlled pressure.
For large containers such as 5kg or 20kg buckets, dual-stage filling or bottom-up filling may be used to improve accuracy and reduce air entrapment. Anti-drip valves ensure a clean cut-off after each cycle, preventing grease residue on container rims.
After filling, containers are transferred to sealing, capping, and labeling systems. The entire process is synchronized through a PLC control system to maintain stable production timing and consistent output across all filling heads.

Maintenance and Operation
Grease filling systems operate under high pressure and require regular maintenance to ensure stable long-term performance. Daily maintenance includes cleaning filling nozzles, checking hopper condition, and removing residual grease from contact surfaces.
Weekly inspections should focus on piston seals, valve performance, pressure stability, and sensor alignment. In heated systems, temperature control units should be checked to ensure consistent heating performance.
Because grease is highly viscous, buildup inside pipelines is a common issue if cleaning is not performed regularly. Preventive cleaning schedules and proper lubrication of mechanical components are essential for reducing wear and maintaining accuracy.
With proper maintenance, the machine can operate reliably in continuous industrial production environments with minimal downtime.
