CONVEYOR OVENS FOR CONTINUOUS PROCESSING
Despatch Conveyor Ovens are designed for process versatility and reliability. They achieve superior air temperature uniformity
on all interior parts due to high-volume, vertical down airflow. The continuous belt design is ideal for large quantities
of similar work pieces being processed. Typical applications include pre-heating, curing, bonding, drying and heat
treating. Options include Class A models specifically designed for flammable solvents and a HEPA (High Efficiency Particulate
Air) filtered model for applications that require Class 1000 cleanliness. These ovens provide extremely consistent
and repeatable process results.

CUSTOM CONVEYOR OVENS
Eyeglass Lenses
An optical manufacturer needed a conveyorized thermal processing oven to dry the coatings on its eyeglass
lenses. Despatch designed a custom PC Series conveyor oven with HEPA filtration to meet the customer’s
requirements for high-volume production while maintaining a clean
internal atmosphere.
The conveyor oven operates at relatively low temperatures and was
designed to be compatible with the customer’s robotic loading equipment.
The PC Series Conveyor Oven features superior temperature uniformity
with temperatures up to 260°C (500°F). Conveyor speeds are variable
and Class A models are available.
Glass Processing Conveyor Oven
The Despatch Glass Processing conveyor oven was designed for high volume touchscreen and LCD glass
manufacturing. The system incorporates infrared heating technology with a continuous belt for fast heat up and
processing of the product. We know all LCD glass manufacturing processes are unique and we are here to help.
We are committed to working with our customers to learn the details of their touchscreen and LCD glass process
in order to design and engineer a custom piece of equipment that will
meet each customer’s specific processing needs.
Our infrared systems consist of a load station, multi-zone infrared heating
and cooling sections and an unload station. Despatch infrared conveyor
ovens include a patented drop down chamber for easy maintenance, the
ability to control atmosphere to reduce oxidation and closed loop temperature
controls for tight uniformity. Systems are controlled by an industrial PC
and contain a custom Despatch furnace control application with an easy
to use graphical user interface.
Low Temperature Conveyor Oven for Curing Application
Despatch has manufactured a low-temperature, conveyor oven for a global medical technology company to use
in their unique curing application. The oven design is unique in that it includes two belts to allow two separate
product streams to be processed in the oven. Another unique feature is
the 260°F temperature rating which allowed us to use an FDA approved,
continuous fabric polyester-butyl belt that provides a solid product support
surface. Despatch worked closely with the customer to lay the oven out
with control devices and maintenance access positioned to optimize
access at the installation location.
Custom Conveyor Oven for Sterilizing Surgical Devices
Despatch has designed and manufactured a custom conveyor oven for
a global surgical device supplier. The oven features a 44” wide stainless
steel flat wire process belt that passes through a 650°F heated zone, then through a cooling zone with ambient
air cooling. Further cooling time is provided on an extended outfeed section which is equipped with an exhaust
hood that can be ducted to a customer supplied stack. The oven is also
equipped with HEPA fresh air filters in the heating and cooling zones to
help maintain low particulate air within the process chambers.
Despatch provided a detailed FAT acceptance test on completion of this
project. To ensure the oven was designed and adjusted properly prior to
leaving the factory, the customer sent a set of specialized trays used in
their process to incorporate into the FAT acceptance protocol. Despatch
test technicians and engineers used their understanding of oven dynamics
and heat transfer, as well as documentation from similar ovens, to rapidly
set up and execute the acceptance test and approve the unit for shipment.
