Industrial ovens are a vital part of any metal or electrical-based manufacturing. This makes it vital in industries that combine both these elements. Aerospace manufacturing has a special need for industrial oven manufacturers. The requirements of high quality parts along with safety rules mean that the role of parts manufacturers is crucial.
Industrial ovens play a vital role in the aerospace industry. We need ovens for parts manufacturing and refurbishing. Ovens are used for a range of purposes — from curing composites, to drying paints, annealing metals, and soften parts for repair and maintenance. Ovens are used to manufacture various parts, hone applications, finish the parts and in carrying out repair work.
Common features in aerospace industrial ovens
Aerospace industrial ovens have to be built with large capacity with well proven designs. We are dealing with very large parts such as wings of an airplane. There cannot be too many small parts in the design, since it can impact the integrity of the overall construction.
Aerospace ovens must be of robust construction as they deal with heavy objects and heat wear and tear. We need ovens that can withstand heavy duty cycles when the oven is put to almost constant use. Industrial ovens mean a very high capital outlay and the last thing you want is the oven breaking down because it simply wasn’t built to last. A construction that is meant to last year’s is essential.
Efficient air circulation
In ovens that require high heat such as annealing ovens, efficient air circulation is critical. Otherwise, we will have a buildup of heat which can completely change the heat profile, give us undesired results, damage parts and pose a security risk. These factors are equally true for mid-range heating ovens. Efficient heat circulation allows for even heat treatment. Industrial oven manufacturers use different methodologies to ensure that air circulation is made as effective as possible.
Wide range of temperatures
With the many applications of the industrial oven in aerospace comes the requirement of wide range of temperatures. Certain functions require very high heat, such as annealing, drying or melting. Some functions like annealing require high temperature in the beginning and then sustained heat, followed by cooling. Ovens have to facilitate the whole spectrum.
An oven is subjected to heavy corrosive elements. Metals, when they melt, can turn corrosive. Most industrial ovens are built from high ferritic grade stainless steel. It is preferred because of its high resistance to corrosive elements like moisture or acids. Sometimes steel may have added coating to add to its corrosion resistance. The interior is lined with stainless steel, including shelves and racks. Without proper corrosion resistance, the oven will start rusting quickly. This increases maintenance and part replacement costs. Over time it will cause a complete breakdown of the machinery.
The modern ovens have extremely user friendly features. These are built with control panels that make it easy to control the setting and working of the oven. Today industrial oven manufacturers build control panels with digital process timers and an interface that is extremely easy to understand and use. The intention is also to make automation as smooth as possible. The ovens can be programmed well in advance of the process to ensure that production carries out seamlessly.
Explosion relief panel
This is a security measure that is a must for any oven and furnace today. With high heat and vapour conditions in an oven, we have to take adequate security measures to ensure that there is no fire risk. The ovens have built-in redundancies, such as motorised gas-valves, exhaust fans, safety circuits, recirculation air switches and an established purge cycle. Most of these measures are mandated by fire safety codes. In addition, we can also have sprinklers within the oven and ducts for immediate dousing of any fire.
Almost every industrial oven manufacturer provides a spares kit with the oven. This is especially important if the oven has been customized. The spare kits make maintenance easier and quicker when a part starts to give away, rust, corrode or malfunction. Buying new parts takes time, which can be very expensive for a manufacturing unit. So, spare parts become essential.
