Metering and mixing technology means the processing of one or two component materials. These could be greases and oils or adhesives and sealants such as polyurethane, epoxy or silicone. Single component materials are frequently used 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 and mixing machines are used for the processing of one component (or one-part) material. This could be greases and sealants or pastes and adhesives such as polyurethane, epoxy or silicone.
2K metering and mixing is more complex than 1K metering because the two components are not only metered and applied but also mixed before the application. A given mixing ratio must be adhered to closely and the mixture must be perfectly homogenous. This process relies on one of two available technologies:
