Metering, mixing and dispensing technology from A to Z

1K and 2K metering

What is the difference between 1K metering and 2K metering?

Metering and mixing technology means the processing of one or two component materials. These materials could be greases and oils or adhesives and sealants such as polyurethane, epoxy or silicone. Single component materials are used especially in the automotive industry. Two component materials will be processed in applications like potting or bonding of components, sealing, glazing and many more. For the processing of two component materials, they are filled in separate tanks and are then fully mixed during the dosing process. This could be for example epoxy resin and hardener.

1K metering

1K metering and mixing machines are used for the processing of one component materials. This could be greases and sealants as well as pastes and adhesives such as polyurethane, epoxy or silicone.

Pressure-time-dosing

  • Easiest and most cost-efficient dosing technology
  • Valve opens for a constant period of time and the material will be dispensed under pressure (pressure and flow rate remain constant)
  • Low safety and repeatability
  • Manual metering of adhesives as well as automatic with low quality requirements


Volumetric dosing

  • Most popular possibility for metering
  • Metering with regard to the volumetric quantity
  • Two possibilities:
    • dependent of time: exact defined volume will be metered at a specific location
    • independent of time: volume hast to be metered in a specific period of time over a defined distance or area
  • Automatic dispensing
  • Highest requirements of safety and reproducibility of metering

2K metering and mixing

2K metering and mixing is more complex than 1K metering because the two components have to be dosed and mixed in-line just simultaneously and in the correct mixing ratio. For this process two different techniques could be used:

  • piston pump
  • gear pump technology
