The construction structure material of the machine is 304 stainless steel, accompanied by a material quality certificate. Pistons and dosing heads are meticulously crafted from 316L stainless steel, with corresponding material certificates. The piston gaskets are composed of non-corrosive material, carefully selected based on the nature of the liquid products.

In terms of robustness, the electrical installation and CPU are designed to be waterproof, ensuring durability and reliability. The pneumatic system is equipped with SMC or Festo as the main parts, renowned for their quality and performance.

The Human Machine Interface (HMI) is strategically positioned on the dosed product release side for user convenience. The machine is equipped with a minimum of three emergency stop buttons – one near the touch screen, another near the empty product insertion side, and one located at the back of the machine.

When it comes to components, the CPU and HMI boast brands from Europe, Japan, and China, ensuring a combination of advanced technology and reliability. Electrical components are sourced from Schneider, a trusted name in the industry.

The electric installation is meticulously organized, with each cable identified and documented through a single-line electrical diagram covering the entire system. Ball bearings and seals are sourced from SKF and other top-level Chinese brands, ensuring optimal performance.

The machine features servo-driven diving filling heads for precise dosing of liquids. Pneumatic shut-off and anti-drip filling nozzles enhance the accuracy of the dosing process. As a standard feature, a drip tray is incorporated, further ensuring a clean and efficient operation.

HOw the automatic piston filling machine working?
The operation of an automatic piston filling machine, such as the ones provided by Shanghai Npack, is both intuitive and efficient. This type of filling machine shares common features with others, incorporating essential components like pistons and advanced control systems including PLC (Programmable Logic Controller), frequency converters, and motors.

At the core of the piston filling machine is the volumetric filling mechanism, where precision is key. The pivotal components in this process are the piston and cylinder. The system operates on a straightforward stroke movement principle, facilitating the accurate measurement and dispensing of liquids into containers.

The operation begins with the pulling of the piston, allowing the liquid to enter the cylinder. Subsequently, the piston is pushed, transferring the precisely measured liquid into bottles. This systematic pull-and-push movement is reminiscent of a syringe, ensuring a reliable and efficient liquid filling process.
