A lubricating oil filling machine is built to handle the demanding requirements of industrial and automotive oils, including engine oils, gear oils, hydraulic fluids, and greases. These products often have a higher viscosity than edible oils and can contain additives that may be abrasive or corrosive. Therefore, durability and chemical resistance are key design priorities. Piston filling technology is again the dominant choice due to its ability to handle a wide range of viscosities with high accuracy. The machine's construction often incorporates hardened materials for the piston and cylinder to resist wear from abrasive additives. Seals and gaskets must be compatible with the synthetic base stocks and additives used in lubricants to prevent degradation and leaks. For filling large containers like drums or pails, a dedicated overhead piston filler with a long nozzle is used. Automation is common in lubricant blending plants, where fillers are integrated with conveyors, cap tighteners, and labeling systems to create a high-volume production line. Ace-Filling's lubricant filling machines are engineered for reliability in this tough environment, ensuring precise fills, minimizing downtime, and standing up to the challenging nature of the products they are designed to package.
