Volumetric Servo Piston Filling Machine
Piston filling machine is one of the most popular liquid filling machine for its universal ability ,piston filling machine can fill thick and highly viscous products, such as chunky, semi-paste, paste products, also extensively utilized to fill chemical preparations, such as adhesives, greases, epoxies, waxes, and lubricant oils, also an optional for filling thin liquid
The piston filler is one of the main product of Npack, most of Npack liquid filling dispenser are applying in the fields of Daily chemicals, cosmetics, Food&beverage,personal care products, pharmaceuticals, Oils products.As piston filling machine are solely based on conventional volumetric technology, these are easy to operate and relatively low cost for the majority of the end-use industries.
What is advantage of the piston filling machine?
- Widely application of liquids, such as viscous liquid, shampoo, lotion,cream;Food sauce;foamy liquid,hand liquid soap,detergent.
- High Performance and accuracy,easy operation.
- 30%-40% filling efficient compare with some other types of liquid filler which is base on same number of filling nozzles
Npack as a manufacturer of piston filling machine, we know well what is disadvantage.
High Maintenance Cost and Leakage Issues,Piston fillers are difficult to clean after usage and thus require high maintenance cost. Chances of leakage is also high with the usage of piston fillers. Latest variants are expensive and would incur high installation cost. Often, debris block the pipeline and the nozzle of the filling drips the liquid.
For this disadvantage, how we solve and avoid these?
- The liquid feature and how many types of liquid determine if you will choose a piston filling machine, normally we suggest users using one piston filler for one type of liquid, but this will increase cost. One product using one piston filler can save time for cleaning, and we can choose suitable O rings, seals for the piston. We have customer , they are OEM factory, they filling alcohol, windshield water,detergent, shampoo in one machine,Normally we do not suggest customer to do that, for the disadvantage of the piston filler. And no piston seals can work for all types of liquids.
- Npack Piston filling machines have automatic cleaning system and automatic piston take off system, this required a piston filling specialist operator, need to be trained.
Npack design many types of filling nozzles, with shut off nozzles, anti drops nozzles.
If we know well about the piston filling machine, then we know that, one liquid using one set piston filling machine is the best choice.
How a piston filling machine working?
This is a very old and classic topic,nowadays, after some years technology developed, the piston filling machine working more efficient and intelligent.Generally speaking,it is a rod with piston head to pull and push the liquid in and outside of the piston cylinder, the volume is controlled by the stroke distance.
- From the different source of power,have pneumatic, motor or manual driven
- From the automation degree have automatic, semi automatic and manually one
- The automatic piston filling machine can be single head and multi head, more heads more capacity,but not Straight up, for moving and action takes time.
By application fields will be Food and Beverages,cosmetics, pharmaceuticals,etc.
