  • 350°F. LEWCO Oven used for Heating Wheel Resonators

    LEWCO, Inc. recently delivered a small walk-in oven to a Tier 2 Automotive Manufacturer of rubber and plastic air induction system parts, as well as other under-hood components. The oven is electrically heated and has a maximum operating temperature of 350°F. It will be used to heat wheel resonators, which are used to reduce tire cavity noise. The oven, which features a workspace of 60”W x 60”D x 60”H, was manufactured and designed to NFPA 86 “Class B” standards. The oven has a top mounted heater-box with 36kW heat input...

  • LEWCO Designs Conveyor Ovens for Hose Clamp Manufacturer

    LEWCO, Inc. recently delivered two continuous conveyor ovens to a manufacturer of specialty hose clamps. The ovens, model CVB03ED, will be used to heat treat various hose clamps up to 350°F. Both ovens were designed to meet the requirements of NFPA 86, Class A ovens due to residual oil and other lubricants being present on the parts. Each oven features a top mounted heater-box with 36kW heat input. A 700 CFM circulation fan delivers dual airflow throughout the workspace. The control system includes a single set-point process temperature controller, redundant...

  • Wisconsin Oven Ships Tempering Oven to Flame Treating Systems

    Wisconsin Oven Corporation shipped one (1) natural gas fired draw batch oven to Flame Treating Systems Inc in Durham, NC to be used for tempering various steel parts. Flame Treating Systems Inc. provides customized flame hardening systems to customers along with in house flame hardening services. The addition of this tempering oven allows them to efficiently temper their customers parts in house. The tempering oven has a maximum temperature of 1250°F and basket dimensions of 4’ W X 3’ H X 4’ L. Steel parts are loaded into the...

  • LEWCO Designs Continuous Process Oven for Automotive Manufacturer

    When a leading Tier 2 Automotive Manufacturer was in need of a large oven to cure polyurethane foam, they turned to the experts at LEWCO. The result was a custom, high-efficiency, field assembled, continuous process oven. The customer’s process consists of filling aluminum molds with polyurethane foam. The molds are fixed on steel carriers which pass through the oven at 176°F. to cure the foam. Once the mold reaches the end of the oven the foam is transferred to the next step of the process.  The oven features a...

  • Long Dwell Times & Limited Space Pose Design Challenge

    LEWCO, Inc. recently delivered (2) custom conveyor ovens to a large multi-national manufacturer of electrical insulators. The ovens will be used to cure a proprietary coating on various parts up to 248°F. A solvent in the coating required both ovens be designed to meet the requirements of NFPA 86, Class A ovens.    Curing part coatings at low temperatures is relatively simple; however this project posed a little more challenge to engineers. They were faced with designing two different ovens. The first oven had to meet long dwell time...

  • LEWCO Conveyor Oven Preheats Plastic Valve Assemblies for Automotive Supplier

    Shortly after delivering a compact conveyor oven to a company in the electric motor industry, LEWCO was contacted by a Tier 1 Automotive Supplier in need of a similar sized conveyor oven. After speaking with the customer and understanding their needs, LEWCO engineers designed a custom conveyor oven, model CVB05ED. The oven will be used to preheat plastic valve assemblies to 240°F, which simulates conditions the valves experience on a vehicle. The valves are then subsequently pressure tested to ensure proper function and reliability prior to being installed on a...

Industry Information

Heat Treating Ovens

Heat treating ovens are a type of industrial oven, which are heated chambers used for industrial applications, including drying, curing or baking parts and final products. Heat treating ovens are used to alter the chemical and physical properties of metal or glass, including their hardness, tensile strength and toughness, through a three-step process of heating, cooling and reheating.

Heat treating ovens may perform a number of heat processes, including quenching, case hardening, precipitation hardening, tempering and annealing. Quenching is the process of cooling a metal at a rapid rate. In ferrous alloys, this process will produce a harder metal, while in non-ferrous alloys, like copper, aluminum or nickel, it will produce softer metal. Case hardening is a thermochemical diffusion process in which an alloying element, like nitrogen or carbon, diffuses into the surface of a monolithic metal. The result is a solid solution that is harder than the original material, which improves its wear resistance without compromising its toughness. Precipitation hardening, also known as age hardening, is a heat treating process that increases the yield strength of most malleable materials. These materials include most structural alloys of aluminum, nickel, titanium, magnesium and some steels and stainless steels. In superalloys, precipitation hardening is known to produce yield strength anomaly, which provides excellent high temperature strength. Tempering increases the toughness of iron-based alloys. Usually performed after hardening to reduce some of the excess hardness, tempering is completed by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air. Finally, annealing is a rather general term that refers to the heating of a metal to a specific temperature and then letting it cool very slowly, at a rate that will produce a fine microstructure. The microstructure will be either partially or fully separated from the constituents. Heat treating ovens are employed with this technique most often to soften a metal for cold working, to improve machinability or to enhance properties like electrical conductivity.

Heat treating ovens can generally be split into two groups: batch ovens and continuous ovens. Batch ovens are usually loaded and unloaded manually. Continuous ovens, on the other hand, have an automatic conveying system that provides a constant load into the oven chamber. Industries in which heat treating ovens are employed include: aerospace, automotive, composite and specialty materials, medical, dental and military and defense. Heat treating serves these industries well by providing them with glass and metal that has improved strength, hardness and toughness.
