Grunfeld specialises in designing and manufacturing systems for filling and packaging liquids and pastes into – Bottles, Tubes, Pots, Cartridges, Twin-Cartridges, Chubs, Pails, and Drums
Grunfeld also designs and manufactures dispensing systems – for dispensing, dosing and depositing bulk liquids and pastes.
The range includes Automatic Bottle Filling (with a range of dosing technologies available to suit the requirements), Bottle Capping (for regular caps or more complex closures), and option for further downstream processes.
The range includes Tube Filling System for Plastic, Laminate and Aluminium Tubes, with automatic infeed of empty tubes, orientation, filling, and sealing, along with options for further downstream processes.
The range includes Semi-automatic Filling Systems, and Automatic Filling Systems (with option for further downstream processes). Along with a range of Presses (for Drums or Mixing Vessels) to feed the Filling Systems.
The range includes systems that fill by weight (for lower viscosity products) and systems that fill by volume (for high viscosity products), along with a range of Presses to feed the Filling Systems
The range includes systems to fill cartridges in a vertical orientation, and a horizontally orientation, along with a range of Presses (for Drums or Mixing Vessels) to feed the Filling Systems
The range includes Semi-automatic Filling and Piston Insertion Systems, and Automatic Filling Systems. Along with a range of Presses (for Drums or Mixing Vessels) to feed the Filling Systems.
The range includes Automatic Foilpack/Chub Filling (Form, Fill and Seal) systems in horizontal configurations, along with a range of Presses (for Drums or Mixing Vessels) to feed the Filling Systems
Dispensing Systems for a wide range of applications – Moulding & Casting, Panel Lamination, Gluing & Bonding, Sealing & Gasket, Potting & Encapsulation, and Fluid Transfer.
The range includes Hydraulic Discharge Presses for 200 litre (55 Gallon) Drums, and Customised/Bespoke Hydraulic Discharge Presses for Mixing Vessels

Why Machine Design Matters: Material Compatibility
When designing a filling machine, one critical factor often underestimated is material compatibility—specifically, the compatibility between the machine’s fluid-contact parts and the fluids being filled.

A brief description of each dosing technology discussed in this blog
Piston Dosing – A piston is driven inside a cylinder, moving a set distance to displace the liquid or paste.
