Totally accurate and cost-effective, DualSave is a dosing system able to regulate two feeders connected to the same neckpiece with a single control unit.

Utilizing propriety design and algorithms based on LIAD’s single channel feeder “ColorSave”, DualSave ensures consistent feeding when working with a variety of materials.

DualSave can be configured for either weight or volumetric feeder, and can be used for injection molding, extrusion or extrusion blow molding applications.

DualSave Advantages

  • Unparalleled accuracy and precision
  • Easy and intuitive control unit
  • Unmatched cost-savings
  • Improved quality of final product
  • Vastly reduces the amount of rejects
  • Stores up to 500 recipes, shortening setup time
  • Easy replacement of feeding screw
  • Ability to combine gravimetric and volumetric channels
  • Compensation of masterbatch amount when using scrap material

Multiple Applications

DualSave can be used for the following applications:

  • Injection molding
  • Extrusion
  • Extrusion blow molding

DualSave Compensation Feature

The DualSave controller contains a built-in feature called “Compensation” that can be used when one of the channels is volumetric and feeding scrap material and the other channel is feeding masterbatch either by gravimetric or volumetric channel.

As the scrap material already contains masterbatch it is possible to reduce the amount of masterbatch to be used in the other channel. This provides substantial production cost savings.

For example, if a recipe calls for 5% masterbatch in one channel and 20% scrap material in the other channel, DualSave automatically reduces the masterbatch percentage to 4%. By the same instance increasing the scrap to 40% reduces the masterbatch to 3%.

Using a capacity sensor in the scrap channel ensures that when there is no more scrap material the percentage of the masterbatch returns to its original percentage.
