A weighing filling machine line is an automatic filling system that uses load cells to measure product weight during filling. It is ideal for medium and large containers where accurate weight-based filling is required.

It is widely used for lubricating oil, edible oil, chemical liquid, liquid detergent, disinfectant, fertilizer liquid, coatings, and other liquid or semi-liquid products.

Sunshine weighing filling machine lines can be customized for 5–25KG pails, 200KG drums, and 1000KG IBC tanks, depending on the customer’s production needs.

Weighing filling is more suitable for large-volume products because it directly controls filling weight. It helps reduce errors caused by product density changes, temperature changes, or viscosity differences.

The filling accuracy can usually reach high precision levels depending on the product, container size, and filling range. Servo control, load-cell weighing, and two-speed filling help improve accuracy and stability.

Yes. The weighing filling line can be customized with anti-foam filling methods, bottom-up filling nozzles, anti-drip nozzles, and special piping systems for viscous or easy-foaming liquids.

A complete line can include container feeding, automatic weighing filling machine, capping machine, labeling machine, inkjet printer, conveyor system, palletizing system, and other supporting equipment.

Yes. For corrosive chemical products, the contact parts can be made with anti-corrosion materials such as PTFE, PVC, PP, or other suitable materials according to the liquid characteristics.

Yes. The line can be designed to handle different containers such as pails, drums, and IBC tanks. Some parts may need adjustment or replacement according to container size and shape.

The filling system can be equipped with anti-drip nozzles, vacuum suck-back devices, and controlled valve closing to keep containers, conveyors, and the production area clean.

It can be semi-automatic or fully automatic. A fully automatic line can complete container positioning, weighing filling, cap feeding, capping, labeling, coding, and conveying with minimal manual operation.

Yes. Sunshine can customize the line according to filling volume, product viscosity, container type, production capacity, material requirements, and factory layout.

Common industries include lubricating oil, chemicals, coatings, food oil, daily chemicals, disinfectant, agrochemical, and industrial liquid packaging.

You should consider product type, viscosity, foaming level, corrosiveness, container size, target capacity, automation level, and available workshop space.

Sunshine provides customized weighing filling solutions with high-precision load-cell control, stable filling performance, anti-drip design, hygienic or anti-corrosion structure, and complete line integration from filling to final packaging.
