Booster,
or Pre-Gel, ovens are used before convection ovens. The object is
to put as much energy into the coating/part as possible within a
short distance to elevate the surface temperature to about 350°F
to induce flow. The length of the oven is dependant upon the line
speed, mass, geometry, and substrate of the part. Typical booster
ovens are from 5 to 15 feet in length. Zoning for these ovens
tends to be minimal, as there is no danger of scorching the
coating at the start of the cure process and the heaters are
operated at their maximum settings. Zoning is limited to
horizontal groups of heaters.
Curing
Ovens
The first object of a curing oven is to melt the powder then allow
it to flow as soon as possible. Downstream of this initial stage,
the heater density is lower to maintain the flow temperature or
"soak stage" until the coating reaches a full cure.
It is also for this reason that proper zoning is critical. It is
important to zone not only the oven top to bottom, but there must
be adequate zoning front to back along the length of the oven. The
length is dependant upon the line speed, mass, geometry, and
substrate of the part. The soak stage of the oven typically
occupies two-thirds of the length of the overall oven.
Control Panels Pre-Programmed at Factory for Maximum Efficiency
and Performance
|
Deluxe
Control Panel
Includes
a PLC and an interface visual touch screen.
The PLC approach is for ovens with multiple zones and gives a
graphical representation of the zone layout and the current
setting for any of the zones. Additionally, once a heating profile
within the oven has been set, this information may be stored as a
recipe number and retrieved next time that particular part is run
again.
Model Numbers:
- DCPIH-1000,
without PLC
- DCPIH-1000PLC,
with PLC

Standard
Control Panel
Includes
timers for zone control from top to bottom and from front to rear.
Recommended only for small curing and booster ovens up to 6 zones.
"Gas-Pulse" zone control utilizes a simple solenoid
that, when shut, allows the minimum gas flow to reach the heater.
When open, the maximum amount of gas flows to the heater. By
operating the 20-second time base percentage timer, precise
amounts of gas are metered into a given heater or zone of heaters.
This approach simplifies the plumbing and installation while
offering an excellent solution that allows the operator to easily
adjust the oven. Model No: SCPIH-500
