350BPH Liquid Filling Machine Oil Paint Semi Auto Capping Line

350BPH Liquid Filling Machine Product Introduction 

The 350BPH Liquid Filling Machine Oil Paint Semi Auto Capping Line is a reliable and efficient solution for packaging viscous and semi-liquid products such as oil paint, edible oil, lubricants, and chemical liquids. The system combines a weighing filling mechanism with a semi-automatic capping unit, ensuring precise volume control and tight sealing performance.

Equipped with high-precision load cells and PLC control, the machine delivers consistent filling accuracy while reducing material waste. Its modular structure allows flexible configuration for different container sizes such as drums, buckets, and cans. The semi-automatic capping system enhances sealing efficiency while maintaining cost-effectiveness for small to medium-scale manufacturers.

This machine is ideal for industries requiring stable output, hygiene compliance, and adaptability, including paint production, food oil processing, and industrial liquid packaging. Its user-friendly interface and durable construction ensure long-term operation with minimal maintenance.

Working Principle：

The machine uses a weighing-based filling system where containers are placed on a load platform. Liquid is pumped into the container, and the filling process automatically stops once the preset weight is reached. After filling, containers are manually or automatically transferred to the capping unit, where caps are tightened using a semi-automatic mechanism. The entire process is controlled by a PLC system to ensure accuracy and consistency.
