STG Square-Port Semi-Automatic Filling Machine

The STG Square-Port Series Semi-Automatic Filling Machine is designed for thick pastes and materials that do not flow easily. It uses a piston filling system powered by a servo motor and PLC pulse control, helping ensure smooth feeding and accurate filling.

It is widely used in the food, chemical, and other industries for filling thick and viscous products.

Key Benefits

1. Accurate and Consistent Filling

The machine features a piston-type anti-drip filling valve to help prevent dripping after filling. The servo motor and PLC pulse control system provide precise filling control, with the filling error ranging from 1 g to 50 g or less, depending on the model.

It also supports several external start options, including a foot pedal, photoelectric sensor, and proximity sensor, making it easy to operate in different production setups.

2. Suitable for a Wide Range of Materials

The STG series is suitable for thick, sticky, and slow-flowing materials, such as:

• Taro paste
• Meat fillings
• Red bean paste
• Fruit pulp and jam
• Resin
• Maltose syrup

Its piston filling system helps handle materials that are difficult to feed, making filling smoother and reducing the risk of poor material flow.

3. Technical Specifications

• Power supply: 220 V / 50 Hz
• Air consumption: ≤ 0.1 m³/min. Compressed air is mainly used for the anti-drip valve.
• Chuck sizes: 50.5 mm / 77.5 mm
• Filling range: Multiple models are available, with a stated range from 5 ml to 1,000,000 ml across the series. The actual filling range depends on the model and product requirements.

Product Features

The STG series has a simple structure and is easy to operate. Its piston filling system helps feed thick materials smoothly, while the anti-drip filling valve helps reduce product waste and keep containers clean.

As a semi-automatic machine, it offers flexibility for small and medium-sized production runs. It is also convenient when changing container sizes, making it a practical choice for factories producing fillings, jams, pastes, and other viscous materials.
