Industrial curing ovens play a very important role in thermal manufacturing processes and present powerful equipment for industrial manufacturers. The main purpose is to achieve a temperature level of different materials within or over a specific limit, in order to improve its mechanical properties, meaning that by applying heat to the material, a chemical reaction is accelerated. Often, solvents are also added in this process, for additional process acceleration.
In general, such ovens are divided into two types, namely batch process ovens, and continuous process ovens. Curing ovens provide precise control (allowing result repetition), uniform airflow (ensuring a complete curing process), as well as ensuring a safe environment. Curing ovens are nowadays easy to use with uncomplicated user interfaces, and with precise temperature control. Other advantages include short cycle times and maximized productivity of the industrial oven. Moreover, proper insulation, in addition to airflow recirculation, guarantees energy efficiency. Therefore, manufacturers have an effective production process, in both quality and costs, whilst ensuring competitiveness in the market, and increased profitability.
Curing ovens are especially utilized in the electronics and semiconductor sectors for epoxy and polyimide curing, which have special process requirements. Further application possibilities of such ovens are huge – from coatings, rubber, and adhesives, to thermoset plastics and composites. Other applications include curing paints and coatings, as well as preheating metals for coating purposes. Further materials also include carbon fibers, ceramics, polymers, and glass fibers. Regarding composite curing, ovens have a uniflow airflow, which means that heated air is delivered from both sides of the chamber, and therefore, the heat transfer is optimized. These are also the most popular materials in the industry.
A segment where curing ovens have a crucial role is the electronics industry sector, with curing electronics. They are used in various curing processes, in order to achieve a specific shape of different materials by applying pressure or heat. Furthermore, the electronics production processes are accompanied by curing coatings for elements such as resistors and capacitors, as well as burn-in testing of RAM and ROM modules. Hence, the quality, longevity, and durability of the electronic components are enhanced, alongside the strength and performance.
Choosing a curing oven considering the options in today’s market can be challenging. However, it is important to ask for expert help and determine the requirements in terms of chamber size and volume, temperature requirements, and airflow patterns. Depending on the size requirements of the loads, available are different solutions for curing ovens, which are also customizable, in case a special configuration is needed. It is also crucial in the selection process to consider curing ovens that meet various quality standards.
