Curing Ovens

Despatch offers a selection of benchtop, cabinet, walk-in and conveyor ovens that are ideal for curing applications. Despatch curing ovens offer fast ramping and cool down rates for maximum productivity, short cycle times and consistent, reproducible curing processes for all product loads.

Curing ovens are used for a variety of applications involving coatings, adhesives, rubber and thermoset plastics and composites. The electronics and semiconductor industries use Despatch clean process ovens for epoxy curing and polyimide curing. Despatch specializes in polyimide curing ovens that are designed to meet the unique process requirements for hard baking polyimide coatings in an inert atmosphere.

Despatch curing ovens are designed to provide tight temperature tolerance and precise control for repeatable results and uniform airflow that ensure proper curing across an entire load. The ovens are exhausted to effectively remove the VOCs given off during curing, ensuring a safe environment. Best-in-class energy efficiency is achieved with superior insulation and cabinet design as well as recirculating airflow management. Despatch offers gas or electric batch ovens for curing small to very large loads and conveyor ovens with multiple zones for continuous processing. If your process requires a custom solution, we can work with you to create a configuration that suits your specific needs.

Despatch offers a wide range of standard and custom ovens for composite curing.  The ovens provide uniflow airflow which delivers heated air from both sides of the chamber for uniform operating temperatures. Typical applications include curing filament-wound composites used in products such as light weight pressure vessels, and curing the composite components of wind turbine blades. Despatch is an established supplier of vacuum bag composite curing systems with numerous systems installed at many of the major aerospace manufacturers.

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.
