Technical Parameters

Main Components of a Semi Automatic Liquid Piston Filling Machine

1. Frame and Worktable

Built with a stainless steel structure, providing strong support, durability, and easy cleaning for daily operation.

2. Piston Dosing Unit (Core Component)

Consists of a high-precision cylinder, piston, seals, and check valves to ensure accurate and consistent filling volumes. It is typically driven by a servo or stepper motor for precise control.

3.Product Tank / Hopper

Used to store the product to be filled. Made of food-grade stainless steel, with a simple design that allows easy cleaning.

4. Filling Nozzle

Different nozzle designs are available based on product characteristics. Immersion nozzles help reduce foaming, and optional anti-drip devices keep the filling area clean.

5. Control System

Operated via PLC or a control panel, allowing easy adjustment of filling volume and speed, with support for multiple parameter settings.

6. Lifting and Operation Components

The filling head height is adjustable to suit different container sizes. Foot pedal or two-hand start controls are used to ensure safe operation.

Semi Automatic Liquid Piston Filling Machine Working Process:

1. Liquid or paste put into hopper manually
2. Adjustable the right volume by hand wheel
3. Put the container under the filling nozzle
4. Step foot valve to start one-time filling
5. Remove the full container and put the next container under the filling nozzles
6. Repeat
