Despatch is a leading industrial oven manufacturer with a wide range of industrial oven and furnace designs to accommodate a variety of load sizes and production volumes. Our ovens are known for tighter temperature tolerances, higher yields, and consistent, repeatable results, delivering invariable, uniform temperature for as long as the oven is in service thanks to its solid build quality and design.
Despatch laboratory ovens are high-performing and built from corrosion-resistant materials. Our standard line of benchtop ovens includes forced convection ovens, high-performance laboratory ovens, industrial production ovens, Class A ovens, stackable clean process ovens, test ovens, burn-in ovens, and benchtop furnaces. Our ovens are versatile enough to handle a wide range of applications and provide exceptional heating accuracy, temperature uniformity, and process
Despatch’s cabinet ovens are designed for easy reach-in loading and unloading. Our standard line of cabinet ovens includes forced convection ovens, lab ovens, industrial production ovens, cabinet furnaces, and clean process ovens. They also include polyimide curing ovens, catheter curing ovens, paint sample curing ovens, inert atmosphere ovens, and top-loading ovens. These batch ovens provide a small and efficient footprint and a wide range of chamber sizes.
Suitable for loading manually or by forklift, these batch ovens are ideal for a broad range of applications including aging, bonding, curing, drying, baking, heat treating, annealing, and stress-relieving. They feature industrial ruggedness, excellent process control, and dependable operation. Our standard line of truck-in ovens have chamber capacities ranging from 52 to 952 cubic feet and temperatures from 650°F to 1000°F.
Industrial Conveyor Ovens for Continuous Processing
Despatch conveyor ovens are versatile, reliable, and achieve superior air temperature uniformity on all interior parts due to high-volume, vertical down airflow. Their unique belt design is ideal for large quantities of similar workpieces being processed. Options include Class A models designed explicitly for flammable solvents and a HEPA filtered model for applications that require Class 1000 cleanliness.
Industrial ovens are heated chambers used in the production processes to enhance product quality, strength, hardness, and longevity. They are available in a range of sizes, configurations, and temperatures.
An Industrial Oven is used in a wide variety of industries, including manufacturing, chemical processing, healthcare, transportation, and electronics. Common applications include annealing, curing, drying, baking, aging, and heat-treating parts, and products.
They can also sterilize medical instruments, heat treat 3D printed parts, compact and materials, burn-in test parts and products, and remove pyrogens from pharmaceuticals. In addition, industrial ovens activate adhesives, meld materials, shrink, preheat, melt, laminate, and bond materials thermally.

Annealing – Heating and slow cooling in order to toughen and reduce brittleness.
Drying – Removal of moisture (water that is not chemically bound).
Sterilization – Eliminates or kills all forms of life present on a product.
Burn-in Testing – Process of stressing components to test for failure.
Aging – Rapid Weathering of Metal to achieve a stable surface condition. Curing – Controlled heating of a substance to promote or control a chemical reaction.
Baking – Heating to a low temperature in order to remove entrained gases. Dehydrogenation – The use of dry heat at high temperatures to destroy pyrogens.
Heat Treating – Changing metal properties such as hardness, strength, flexibility, and stress resistance
DETERMINE WHETHER A BATCH OR CONTINUOUS MODEL OVEN WILL WORK BEST
For applications where the load size or production volumes vary substantially, batch processing is a good approach. Batch ovens are also ideal for situations that require a high degree of flexibility in terms of process variables such as temperature or dwell (soak) time.
Where a large quantity of similar product pieces are processed, continuous operation may be the optimal approach. Continuous ovens help ensure consistent thermal processing times of each part in high-volume application, such as manufacturing electronic components or automotive parts. Continuous ovens may also allow several discrete processes to be combined, reducing material handling, and increasing throughput.
STEP 3 CHOOSE THE BEST CHAMBER SIZE TO SUIT YOUR PROCESSING NEEDS
Lab or Benchtop Ovens
Because of their small, convenient size, these ovens are used for laboratory test and development applications, as well as production applications that require small batch loads. These ovens range in chamber size from 1 cubic foot to 27 cubic feet (28 to 764 liters).
This size is referred to as a reach-in oven because they are ergonomically designed for easy loading and unloading. Cabinet ovens are floor mounted, very efficient in terms of footprint and typically range in size from 4 to 35 cubic feet.
Walk-In and Truck-In Ovens
Large batch ovens can accommodate a wide variety of specific product/process needs. They are suitable for loading by fork truck or manually. Typically truck-in ovens ranges from 52 to 210 cubic feet, and walk-in ovens start at 360 cubic feet and larger.
CONSIDER YOUR TEMPERATURE REQUIREMENTS
When considering the temperature requirements for your application, first note the minimum and maximum operating temperatures required.
Additional temperature considerations include:
The required dwell time at temperature, and the overall cycle time.
The type and amount of product load. The oven design will need to have sufficient heating capacity to bring the product to the desired temperature within the specified time.
Whether the heat-up rate needs to be controlled or if the product can be allowed to reach temperature as quickly as possible.
Any specific cool-down requirements.
STEP 5 KNOW HOW CRITICAL TEMPERATURE UNIFORMITY IS FOR YOUR PROCESS
9 Point Uniformity Survey
Before implanting a critical thermal processing step you need to confirm that the oven you are using is delivering the temperature uniformity required for your process.
A nine-point uniformity test that measures temperature in every corner as well as the center of the oven will ensure that the temperature throughout the oven remains constant.
CHOOSE THE BEST AIRFLOW FOR YOUR PRODUCT LOAD
Consider how parts can spaced with each type of airflow to ensure optimal airflow through or around all parts of the load.
