AB glue dispensing machine is an automated device designed to precisely control, mix, and dispense two-component (two-part) adhesives, commonly known as AB glue. These machines mix the two separate components—Glue A (main agent) and Glue B (curing agent)—in specific ratios (e.g., 1:1, 2:1, 10:1) and dispense the mixed adhesive for purposes like bonding, coating, sealing, waterproofing, and potting. The glue types typically handled include epoxy resin, polyurethane, and silicone.
The machine generally consists of two barrels for the separate AB components, metering pumps to control the amount of each glue for correct ratio mixing, and a mixing head with a dynamic stirring motor that thoroughly blends the adhesives before dispensing. Some models include automatic cleaning functions to clear residual glue from the mixing tube and components, and heating systems to maintain glue fluidity in various environments.
AB glue dispensing machines vary by complexity:
-
Simple machines use gas pressure to mix and dispense glue with fixed ratios, suited for low-end applications.
-
Semi-automatic AB glue dispensing machines can mix different glue proportions automatically but without a motion control platform.
-
Fully automatic AB glue dispensing machine integrate automatic mixing with motion control platforms for precise, three-dimensional dispensing paths, controlled by computers, suitable for complex and high-volume production.
These machines are widely used in industries involving LED displays, electronic components (like power supplies, sensors, PCBs), solar panels, sensors, and products requiring precise adhesive application in irregular shapes such as points, lines, arcs, or circles.
