New generation gravimetric blenders Piovan helps improve the quality of performance of production lines and changing technical standards and applications, delivering exceptional qualities of flexibility, precision, safety and efficiency.
Flexible, safe and accurate


Expandable configuration:  can be initially equipped with two dosing stations, to subsequently be expanded to three, four, five or six, by simply adding station modules. The control self configures depending on the number of stations installed.

Portability of dosing station from unit to unit: No more need of redundant dosing stations or unnecessary cleaning operations. The  stations are interchangeable, facilitate materials management and eliminate ordinary maintenance.

Quick material exchange, spare dosing station: Colours can be managed by associating to them the respective dosing station. The cleaning operations at colour change are reduced to minimum.

Simplified cleaning operations: accessibility to weighing pan and mixer chamber is full. Both the weighing pan and the mixer shaft are removable without the use of tools. Speed of operation is guaranteed.

Improved homogeneity of the blend: Once the ingredients are accurately dispensed, a critical phase of the blending operation is the homogenization one. The new  mixer, with its spherical shape and circular paddle shaft, provides total homogenization of the different materials with no risk of segregation or powder generation.

Suitable for all materials:  virgin, masterbatch, regrind, reprocessed, long fiber, filled or any particular granulometry, shape and bulk density, are elements characterising the vast range of materials to potentially blend. The very innovative design of  allows the handling of any possible raw granular resin.

For machine throat mount:  is the first gravimetric batch blender that is mechanically and electronically isolated from vibrations. One very critical element for the selection of the correct device to use, when blending is necessary, is the level of vibration of the processing machine, as the blender must ideally sit on it.

Precision and repeatability: Accuracy of blending is guaranteed also in those circumstances of excessive vibrations or moving of the processing barrel.  can be equipped with remote mixer unit so to position the blender on a floor stand and install the mixer unit on the machine. Precision of dosing, homogeneity and repeatability of the ingredient ratios are so guaranteed.

Immune to vibrations.


Q7: The smallest of the  line for capacity ranging from 2 through to 100 kg/h. The number of dosing stations can be 2 up to 4. The dosing devices can be slide gate or dosing auger (sul lato dx mettiamo il disegno tecnico con le dimensioni della macchina)

Q12: With capacity ranging from 20 through to 150 kg/h and a combination of 2 up to 6 ingredients. The dosing devices can be slide gate or dosing auger (sul lato dx mettiamo il disegno tecnico con le dimensioni della macchina)

Full accessibility


Standard:  is a very compact, flexible, complete gravimetric batch blender boasting the very latest technologies and design for precise weighing and mixing.

On floorstand: all  models can be installed on the machine feed throat or beside the machine on a floorstand. The larger models can also be configured for central production of blend and distribution to several users. All models and respective floor stands and modular and expandable.

With remote mixer:  is designed to withstand all possible vibrations coming from an injection moulding machine or an extruder, however, in all those applications where the plasticising unit moves,  can be equipped with remote mixer unit. The blend is produced by the unit on the floor and homogenised at the machine right before being processed.

Remote mixer unit: entirely made of stainless steel and perfectly replicating the unique and distinctive characteristics of the integral mixer of , the remote mixer unit can be placed on any injection moulding machine or extruder at any distance from the blender unit. One blender unit can feed more mixer units. The batch is entirely conveyed to the mixer unit every cycle, so to keep the ingredient proportions intact.

Packaging: Multitude of processes 

Injection moulding, extrusion or extrusion blow moulding are processes that generally need different kinds of blenders.

With its  range of gravimetric blenders and broad engineering capabilities, Piovan fulfills all requirements by providing the most suitable solution.[Gravimetric blender]
