Metering and mixing relates to 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 particularly common in the automotive industry, while two-component materials can be seen in applications such as component potting and bonding, as well as sealing, glazing and many more. When processing two-component materials, the components must first be filled in separate tanks and then accurately and uniformly mixed. This is the case for example in the processing of epoxy resins and hardeners.
