Introduction
Considerably less expensive than XY system alternatives, the Exact Model 2497 Circular Bead Dispenser offers excellent performance and affordable pricing. Circles up to 8” in diameter are achievable; larger confi gurations can be quoted upon request. A typical unit consists of a yoke on which a dispense valve, syringe or other device can be mounted.
The unit can be used with single component materials, or can also be easily integrated with Exact’s meter/mix and dispense
systems for use with plural component reactive resins. Numerous feed options and dispense valves are available to provide turnkey systems.
The shot size/duration can be precisely controlled through:
? Variable speed motor
? Shot timer
? Line pressure
? Automatic or manual control
An adjustable vacuum pullback is available on cartridge models which eliminates dripping of thin fl uids.The standard model uses an SCR motor drive and a solid state timer to control the rotational duration. For more critical rotational repeatability, the 2497 is available with a stepper motor. This option is well suited to applications where there is a need to take incremental shots through portions of an arc, to dispense a continuous bead through a partial arc, or to come to the same “home” position on each part after a full dispense cycle.
