Power Train Applications

Power train encompasses any material dispensed on a vehicle’s engine, transmission, axel components, or braking system. Dispensed material acts as a seal to prevent material from escaping a housing or a gasket to ensure components do not leak over time.

Nordson has many years of experience in automotive power train applications, including solving the common challenges of material curing and bead placement.

Material Curing: Many gasketing materials are classified as room temperature vulcanization (RTV). These materials cure at room temperature by simply coming into contact with the moisture in the air. This can cause an issue in standard dispense valves that leave the nozzle full of material, with a shutoff point upstream. Once the material sits for too long, the material is plugged and the nozzle must be removed and replaced before production can start up again.

Nordson Solution: The Zero-Cavity dispense valve creates a cut-off point at the very tip of the valve. This prevents any air from reaching the residual material, circumventing the nozzle curing issue.

Bead Placement: Bead placement can be in precise grooves, and/or in hard-to-reach areas of a component. Though necessary, this location does result in a particularly difficult reach and programmed motion for a robot.

Nordson Solution: Nordson’s extended 2.5-inch extrude nozzles offer reach inside parts while not limiting valve capability. The breakaway between the nozzle and the valve allows for a part to be bumped and the nozzle to break out of position, preventing damage of the part. For longer reaches, a Zero-Cavity valve can be used with a 3.5-inch stem.
