Annealing

  • Annealing processes are important for the finished strength of glass, metals, plastics, and composite materials. Our Industrial Annealing Ovens are the best medium sized annealing ovens available. Our typical designs heat up to 600°F, making them perfect for strengthening glass, plastics, alloys, and composite materials before fitting, shaping, or stamping. Our annealing ovens specialize at maintaining exact temperatures for the most efficient annealing processes followed by a controlled cooling process in order to maximize the strength gained by the annealing process.

    We make sure that your Industrial Annealing Oven is perfectly suited to meet your application by having the best design and engineering process in the industry. Our engineers and production personnel are all factory trained and have spent years in the field servicing and assembling our Industrial Ovens. During the design process, your sales representative is in constant communication with the engineering and production departments making sure that your every need is met. Contact us today!

    • Oven Chamber Height
      • A custom oven chamber height is important in many annealing processes in order to maintain the proper distance between the product and the heaters, proper air flow and even heat distribution.
    • Conveyor Belt Height
      • The conveyor belt height can be customized to match partnering equipment and can also be adjustable.
    • Conveyor Belt Type
      • Conveyor belt selection is critical to the your annealing process. Just as each annealing process is different, each belt type is as well. Each one fits best for different processing needs. Conveyor belt types available are: Stainless Steel mesh, PTFE coated fiberglass, Nomex, Kevlar, silicone, and more .
    • Product Interface Controls
      • HMI and PLC controls can be custom designed, programmed, and installed to match your application. Our engineers focus on keeping the design of the controls simple and intuitive.
    • Specialized Controls and Communication
      • For sensitive and critical processes, specialized control systems can be installed that send communication, alerts, and alarms to operators or remote monitoring equipment, guaranteeing that if anything deviates from normal specifications that the issue can be corrected immediately.
    • Custom Airflow Impingement
      • The airflow is important in maintaining the proper heat distribution during the heating cycle. Our Industrial Annealing Ovens can be customized for airflow volume or impingement type.
    • Photo Eye Belt Stop Sensors
      • These sensors are placed at the exit end of a conveyor annealing oven and signal operators or robotic assemblies that the product is ready for placement and removal from the belt. They also ensure the product doesn’t drop to the floor and they increase efficiency.
    • Conveyor Belt Fixtures
      • Custom belt fixtures are used for certain products during the annealing process to protect the product, provide exact placement for robotic assemblies, and to ensure that the correct heat distribution is occurring while the product is in the conveyor ovens heating chamber.
    • Belt Indexing System
      • For correct product spacing in conveyor annealing ovens, indexing belt systems are available to ensure proper belt loading and they are compatible with robotic assemblies.
    • Forced Air Cooler
      • Especially important in conveyor annealing ovens, forced air coolers filter and cool ambient air that is directed onto the product as it exits the oven chamber to begin reducing the temperature at a controlled rate, ensuring that maximum strength is retained in the product.
    • Robotic Interface Systems
      • Robotic interfaced PLC and HMI systems streamline production and cut costs. Our robotic interface systems can be as simple as belt fixtures and indexing for loading and unloading, or can be integrated for complete control of the oven.
    • Heat Curtains
      • For conveyor annealing ovens, oven chamber heat curtains are critical to retain as much heat as possible and to maximize the heat distribution for the annealing process.
    • High & Low Temperature Alarm
      • Temperature sensors are a critical part of any conveyor or batch annealing oven. These sensors will alert operators or remote systems if the oven temperature has deviated from the set temperature range.
    • Infeed & Exit Extensions
      • Conveyor belt Infeed and exit extensions can be customized from lengths as short as one foot, to unlimited lengths.
    • Fume Hoods
      • Fume hoods are a critical element to plastic and composite annealing processes. Fume hoods capture volatile exhaust fumes from the oven chamber and vent them out of the working environment.
    • Emergency Stops
      • Emergency stops are important on Industrial Conveyor Ovens where moving parts can become tangled with clothes or products if used improperly. Our emergency stops function, look, and location can be customized to meet your individual preference.
    • Automatic StartUp & Shutdown Systems
      • Automatically starting up and shutting down annealing ovens before and after a production shift ensures that valuable time is not lost preheating the oven or that a failure to manually shut down the oven won’t lose you valuable energy costs and unnecessary wear and tear.
    • Digital Belt Speed Control
      • Digital belt speed controls are a great way to make sure that the process is occurring at a precise and measured rate for accurate annealing and maximum efficiency. The belt speed can be set in either feet/meters per minute or for the retention time the product spends in the oven chamber.
    • Material and Product Spacers
      • Maintaining the proper spacing and arrangement of materials and products in an annealing oven is critical for even heat distribution and airflow in the heating chamber.
    • Lockout Controls
      • Avoid improper usage of your annealing oven with security controls that keep unauthorized personnel from being able to use or change the settings.
    • Belt Direction
      • The belt direction on conveyor ovens can be set to operate in either direction. On ovens with dual conveyors, the belt direction can be set to operate in the same or opposite directions.
