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.

Eyeglass Lenses Despatch custom conveyor oven for curing coatings on 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.

Conveyor Oven for Impact-sensitive Drying Process Despatch custom conveyor oven for impact sensitive drying

During manufacture, 22 caliber rimfire cases are filled with an impact-sensitive primer in a wet state so that the primer is stable. This primer then needs to be dried so it will detonate when the gun is fired. A continuous oven with two conveyors that carry pallets containing 300 casings every 8 seconds was requested. The oven uses a steam heat source with an air temperature limited to 185°F with a Hi-limit controller. Primer dust tends to accumulate during processing so the oven needed to have easy access to the interior for cleaning.

A unique air delivery system was developed using perforated aluminum plates to provide better airflow with a lower pressure loss at discharge. Compared to traditional louvers, the plates are easier to clean and are more cost effective.

Custom Conveyor Oven for Sterilizing Surgical Devices Despatch custom conveyor oven for sterilizing surgical staples

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 500°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.
