NP-VF Automatic Piston Filling Machine

The Np-vf piston filling machine is application for dosing all types of non corrosive liquid,viscous liquid.It is mostly using in the fields of Daily chemicals, Food and phamarceuticals industry.For its wide filling range and flexiable,it is suitable for different types of containers, round, flat and square.No matter you are in the fields of cosmetics, food sauce or daily chemicals, the piston filler is one of the popular solution for measuring your products into container.

The Development of Npack automatic piston filling machine

The first generation Npack Automatic piston filling machine built in the 2012,it was a pneumatic driven system filler, and each piston is driving by a air cylinder;the second generation automatic piston filler is adapt with servo motor driven, a main servo motor drives multy pistons stroke movement;the third generation is application multy servo motors to drive multy pistons working ;and the 4th generation NP-VF piston filler updates the control system,using the emotion controller to replace the PLC control , it has the advantage of more highly working efficient and more easyer operation.As we know piston filling machine is an volumetric liquid filling machine,so the filling accuracy is one of the best performance coomparing to other types of filling equipments.After some years developping, Npack piston volumetric technology with features of high accuracy, high speed and working stable.Let us see the advantage features and disadvantage.
