Batch ovens are a type of furnace used for thermal processing. They are used in numerous production and laboratory applications, including curing, drying, sterilizing, aging, and other process-critical applications. Sizes can vary depending on what type of thermal processing application is needed. Batch ovens are used mainly for single batch thermal processing. Cabinet and bench ovens are smaller batch ovens, and walk in/drive in ovens are larger and to be used for more variations of industrial applications.
Batch Ovens can be used for a wide variety of heat processes including drying, curing, aging, annealing, stress relieving, bonding, tempering, preheating, and forming. Batch ovens are essentially heated boxes with insulated doors that process products one at a time or in groups. The part(s) to be processed are brought into the oven in batches on racks, carts, or trucks. Production requirements can accommodate manual or automated loading.
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. The IUPAC name for an epoxide group is an oxirane.
A heating element converts electrical energy into heat through the process of Joule heating. Electric current through the element encounters resistance, resulting in heating of the element. Unlike the Peltier effect, this process is independent of the direction of current.
Dielectric heating, also known as electronic heating, radio frequency heating, and high-frequency heating, is the process in which a radio frequency (RF) alternating electric field, or radio wave or microwave electromagnetic radiation heats a dielectric material. At higher frequencies, this heating is caused by molecular dipole rotation within the dielectric.
Foam rubber refers to rubber that has been manufactured with a foaming agent to create an air-filled matrix structure. Commercial foam rubbers are generally made of synthetic rubber, natural latex or polyurethane. Latex foam rubber, used in mattresses, is well known for its endurance. Polyurethane is a thermosetting polymer that comes from combination of Methyl di-isocyanate and polyethylene and some other chemical additives.
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as household appliances, aluminium extrusions, drum hardware, automobiles, and bicycle frames. Advancements in powder coating technology like UV curable powder coatings allow for other materials such as plastics, composites, carbon fiber, and MDF to be powder coated due to the minimum heat and oven dwell time required to process these components.
Conformal coating material is a thin polymeric film which conforms to the contours of a printed circuit board to protect the board's components. Typically applied at 25-250 μm(micrometers) thickness, it is applied to electronic circuitry to protect against moisture, dust, chemicals, and temperature extremes.
A UV coating is a surface treatment which either is cured by ultraviolet radiation, or which protects the underlying material from such radiation's harmful effects.
Foam latex or latex foam rubber is a lightweight form of latex containing bubbles known as cells, created from liquid latex. The foam is generally created though the Dunlop or Talalay process in which a liquid latex is foamed and then cured in a mold to extract the foam.
Molded pulp or molded fiber is a packaging material, that is typically made from recycled paperboard and/or newsprint. It is used for protective packaging or for food service trays and beverage carriers. Other typical uses are end caps, trays, plates, bowls and clamshell containers.
Laboratory ovens are a common piece of equipment that can be found in electronics, materials processing, forensic, and research laboratories. These ovens generally provide pinpoint temperature control and uniform temperatures throughout the heating process. The following applications are some of the common uses for laboratory ovens: annealing, die-bond curing, drying or dehydrating, Polyimide baking, sterilizing, evaporating. Typical sizes are from one cubic foot to 0.9 cubic metres (32 cu ft). Some ovens can reach temperatures that are higher than 300 degrees Celsius. These temperatures are then applied from all sides of the oven to provide constant heat to sample.
Burn-in ovens in electronics device fabrication, are designed for dynamic and static burn-in of integrated circuits and other electronic devices, including laser diodes. Typical sizes are from under ten to over 30 cubic feet (0.85 m3), with air or nitrogen configurations. Operating temperatures can go over 260 °C (500 °F), and can use both single and multiple temperature settings.
Reach-in ovens are meant for different industrial applications that may need uniform temperature throughout. The ovens normally use horizontal re-circulating air to ensure the uniform temperature, and can use fans that circulate air, creating the airflow. Reach-in ovens can be used in numerous production and laboratory applications, including curing, drying, sterilizing, aging, and other process-critical applications.
A clean process oven is a type of industrial batch oven that is ideal for high-temperature applications, such as curing Polyimide, and annealing thin and film waters. Clean process ovens may be for air atmospheres, or inert atmospheres for oxidation-sensitive materials. Temperatures can be over 525 degrees Celsius.
Industrial ovens are heated chambers used for a variety of industrial applications, including drying, curing, or baking components, parts or final products. Industrial ovens can be used for large or small volume applications, in batches or continuously with a conveyor line, and a variety of temperature ranges, sizes and configurations.
A concrete plant, also known as a batch plant or batching plant or a concrete batching plant, is equipment that combines various ingredients to form concrete. Some of these inputs include water, air, admixtures, sand, aggregate, fly ash, silica fume, slag, and cement. A concrete plant can have a variety of parts and accessories, including: mixers, cement batchers, aggregate batchers, conveyors, radial stackers, aggregate bins, cement bins, heaters, chillers, cement silos, batch plant controls, and dust collectors.
Photonic curing is the high-temperature thermal processing of a thin film using pulsed light from a flashlamp. When this transient processing is done on a low-temperature substrate such as plastic or paper, it is possible to attain a significantly higher temperature than the substrate can ordinarily withstand under an equilibrium heating source such as an oven. Since the rate of most thermal curing processes generally increase exponentially with temperature, this process allows materials to be cured much more rapidly than with an oven.
Thermal cleaning is a combined process involving pyrolysis and oxidation. As an industrial application, thermal cleaning is used to remove organic substances such as polymers, plastics and coatings from parts, products or production components like extruder screws, spinnerets and static mixers. Thermal cleaning is the most common cleaning method in industrial environment. A variety of different methods have been developed so far for a wide range of applications.
Adhesive bonding is a joining technique used in the manufacture and repair of a wide range of products. Along with welding and soldering, adhesive bonding is one of the basic joining processes. In this technique, components are bonded together using adhesives. The broad range of types of adhesives available allows numerous materials to be bonded together in products as diverse as vehicles, mobile phones, personal care products, buildings, computers and medical devices.
