How to Choose a Suitable Semi-Automatic Filling Machine for 100-300kg Capacity?

Choosing the right semi-automatic filling machine for 100-300kg capacity involves evaluating material characteristics, accuracy requirements, production efficiency, container compatibility, and budget:

1. Identify the characteristics of the filling material
   For foaming liquids like pesticides or coatings, select machines with bottom-up filling and anti-drip features. High-viscosity materials may require external pumps or heating systems.

2. Pay attention to filling accuracy
   Machines equipped with high-precision weighing sensors, such as those from METTLER TOLEDO, can achieve filling accuracy within ±0.2%, which is crucial for consistency.

3. Consider filling speed and output
   For 200kg drums, a standard semi-automatic machine can fill approximately 40 drums per hour, depending on manual efficiency. For faster operations, look for systems with responsive nozzle lifting and dual-speed valve control.

4. Check material of contact parts
   If the liquid is corrosive, ensure all contact parts are made of SUS304 or SUS316 stainless steel to guarantee long-term durability and easy cleaning.

5. Evaluate installation space and flow direction
   Choose a model that fits your workspace layout and allows for left-to-right or right-to-left operation. A compact structure with user-friendly manual bucket placement is preferable.

6. Review after-sales support
   Opt for manufacturers that offer remote technical support, spare parts supply, and fast-response service to minimize downtime and ensure continuous production.
