Automatic Net Weight Filling Machine for Bottles, Jars & Tins | Net Weight Filling Machine Manufacturer & Exporter

Product Description

The Automatic Net Weight Filling Machine for Bottles, Jars & Tins is a high-precision weighing-based filling system engineered for accurately filling products by net weight rather than volume. Designed for industries where filling accuracy is critical, this machine is ideal for packaging edible oils, lubricants, paints, chemicals, agrochemicals, food products, dairy products, cosmetic products, pharmaceutical ingredients, powders, granules, and viscous liquids into bottles, jars, tins, cans, buckets, and containers of various sizes.

Unlike conventional volumetric filling systems, the Net Weight Filling Machine measures the exact weight of each container during the filling process using advanced load cell technology. This ensures highly accurate fills regardless of product density, viscosity, or temperature variations, minimizing product giveaway while maintaining compliance with packaging regulations and international quality standards.

The machine features a robust stainless steel construction, precision filling valves, servo-controlled operation, and a PLC-based automation system with an intuitive color HMI touchscreen. Automatic container indexing, weight monitoring, and filling adjustments provide consistent production with minimal operator intervention. The machine supports multiple filling heads and can be customized according to production capacity and container size.

Engineered for continuous industrial operation, the Automatic Net Weight Filling Machine offers exceptional reliability, easy cleaning, quick product changeovers, and low maintenance requirements. It can be seamlessly integrated with bottle unscramblers, capping machines, induction sealers, labeling machines, coding systems, check weighers, carton packing machines, and palletizing systems to create a fully automated packaging line.

As a trusted Manufacturer, Supplier, Exporter, and OEM Partner, we supply customized Automatic Net Weight Filling Machines to customers across the USA, Canada, UK, Australia, Europe, the Middle East, Asia, Africa, and other global markets, delivering advanced filling technology, superior engineering, and long-term production efficiency.

Working Principle

The Automatic Net Weight Filling Machine operates on an advanced weighing principle that ensures every container is filled according to its actual weight rather than volume. Empty bottles, jars, tins, or containers are automatically conveyed into the filling station where each container is accurately positioned beneath the filling nozzle.

Each container is placed on a precision load cell platform that continuously measures its weight during the filling cycle. Once the filling command is initiated, the servo-controlled filling valve opens and dispenses the product into the container. The PLC receives continuous feedback from the load cells and automatically regulates the filling speed to achieve maximum accuracy.

As the target weight approaches, the machine switches from fast filling to slow filling, ensuring precise cutoff without overfilling. When the preset net weight is reached, the filling valve closes instantly and the filled container is transferred to the next packaging process such as capping, induction sealing, labeling, coding, or carton packing.

This intelligent weighing system automatically compensates for variations in product density, viscosity, and temperature, ensuring highly accurate and repeatable filling results while reducing product giveaway and maximizing production efficiency.
