Automatic Piston Bottle Filling Machine

Automatic Piston Bottle Filling Machine for Liquid and Cream Filling

Automatic piston bottle filling machines are used for accurate volumetric filling of liquids, creams, sauces, and other pumpable products. By controlling piston movement, the machine delivers stable filling volumes into bottles, jars, or containers while improving production efficiency compared with manual operations.

This type of equipment is commonly applied in cosmetic manufacturing, food processing, household chemical production, and personal care product packaging.

Different filling nozzle quantities, filling ranges, and conveyor configurations can be customized according to production requirements.

What Is an Automatic Piston Bottle Filling Machine?

An automatic piston bottle filling machine is packaging equipment designed to fill preset volumes of products into containers through piston-driven suction and discharge.

Compared with overflow fillers or gravity fillers, piston filling systems are more suitable for products with viscosity, including:

• Lotion

• Shampoo

• Conditioner

• Facial cleanser

• Cream

• Beverage

• Sauce

• Jam

• Syrup

• Detergent

• Liquid soap

The filling amount can be adjusted through the control system to suit different package sizes.

Main Structure of Automatic Piston Bottle Filling Machine

Product Hopper System

Stores materials before filling.

Optional agitation systems can maintain product consistency.

Piston Filling System

Core filling component responsible for volume control.

The piston size influences filling range.

Filling Nozzle System

Nozzle quantity vary:

• 2 nozzles

• 4 nozzles

• 6 nozzles

• 8 nozzles

• More customized options

More nozzles increase output.

Conveyor System

Transfers bottles automatically between stations.

PLC Touch Screen Control System

Used for:

• Filling amount adjustment

• Filling speed adjustment

Frame Structure

Machine frames commonly use stainless steel construction for durability.

How Does an Automatic Piston Bottle Filling Machine Work?

The complete working process generally includes several stages:

1. Bottle Feeding

Empty bottles enter the machine through the conveyor system and move toward the filling position.

2. Photoelectric Detection

Sensors detect bottle presence and positioning.

Without bottle detection, filling will not start.

3. Bottle Positioning

Containers are fixed under filling nozzles to maintain consistency.

4. Filling Nozzle Descending

The filling nozzles move down into the bottle before filling starts.

5. Piston Filling Process

The piston system draws product from the hopper and dispenses the preset volume.

6. Anti-drip Protection

Nozzles stop product dripping after filling completion.

7. Bottle Discharge

Filled bottles move to capping, labeling, or collection positions.
