Despatch is a company founded on innovation. Working hand-in-hand with our customers we have developed custom thermal processing solutions that have influenced some of the world’s greatest technology breakthroughs over the last 100 years. Despatch is the leading supplier of thermal processing solutions to some of the world’s most sophisticated industries including healthcare, materials, energy and electronics.

Despatch designs and engineers ovens for many different applications. When selecting the type of equipment you will need, there are several considerations to be made, including:
  • The quantity of material to be processed
  • The uniformity, size and shape of the products
  • The temperature tolerance that is permissible


Based on these guidelines, generally one of two types of oven will be selected as most appropriate for a specific application: a batch processing oven or a continuous oven. Applications where large quantities of similar work pieces are processed generally lend themselves well to a continuous operation.

Continuous ovens include the entire spectrum of oven equipment operated on a continuous or indexing basis. These ovens have construction characteristics that generally are similar to batch ovens. The distinguishing characteristics of continuous ovens include such items as the means of conveyance, air distribution techniques and product loading methods.

Conveyorized ovens can be a component in a larger material handling system, including fully computerized systems. In some cases, these ovens can be automatically loaded and unloaded, reducing manual handling and labor costs.

The type of conveyor selected for a continuous application depends almost entirely on the type of products being processed and their configuration at the time of processing. Monorail conveyors are adaptable to a wide variety of work pieces, as many individual work pieces can be positioned on fixtures or racks suspended from the monorail.

Belt-type conveyors are another commonly used means of moving products through an oven. It is important to determine how your products will fit on the belt, i.e., how many parts per lineal foot of belt. The conveyor belt speed is determined by your production parts per hour. The oven length will depend on how long the product needs to be in the oven. Other considerations include the weight of your part and the total weight of the belt moving the parts. Additional types of conveyor systems are: pusher conveyors, powered roller conveyors, drag chains, walking-beam conveyors and screw conveyors.

Despatch’s continuous processing oven portfolio features several models in different sizes with varying conveyor/belt widths. All models are designed for process versatility and reliability and are recognized for superior temperature uniformity in all interior parts due to high-volume, vertical down air flow. Typical applications include pre-heating, curing, bonding, drying and heat treating. Customers looking to optimize their continuous production efforts rely on Despatch to deliver the highest process quality for their application.
