Annealing

  • Annealing processes are important for the strength of metals, plastics, and composite materials. Our HIX Industrial Annealing Ovens are the best medium and light industry annealing ovens. Our typical designs run 600°F and below, making it perfect for strengthening plastics, some alloys, and composite materials before fittings, shaping, or stamping. Our annealing ovens specialize at holding exact temperatures for the most efficient annealing process followed by a controlled cooling process in order to maximize the strength gained by the annealing process.

    We make sure that your annealing oven is perfectly suited to meet your needs by having one of the best design processes in the industry. Our representatives are all factory trained and have spent years in the field servicing and assembling our industrial ovens. During the design process, your representative is in constant contact and communication with the engineering and production department making sure that your every need is met.

    • Oven Chamber Height
      • A custom oven chamber height is important in many annealing processes in order to maintain proper distance between the product and the heaters, while maintaining proper air flow and even heat distribution.
    • Belt Height
      • Belt height is designed to match partner equipment and remain adjustable in order for future changes to process needs or neighboring equipment.
    • Belt Type
      • Belt type selection is critical to the your annealing process. Just as each annealing process has different properties, each belt type does as well, and each one fits best for different processing needs.
    • Product Interface Device
      • An HMI can be custom designed to meet your process needs. Our designers focus on keeping the design of the controls intuitive and simple.
    • Specialized Controls and Communication
      • For sensitive and critical processes,  specialized control systems can be installed that send feedback, notices, alerts, and alarms to nearby workers or remote monitoring equipment, guaranteeing that if anything is out of normal specs then the issue will be quickly handled.
    • Additional Airflow
      • Process airflow is important to promoting the proper heat distribution during a heating. Our ovens can be custom designed for increased airflow or impingement.
    • Eye Stop Sensors
      • These sensors are placed at the exit of an annealing oven and signal workers or robotic pick and place assemblies that the product is ready for it’s next stage, helping prevent product drops and promote efficiency.
    • Belt Fixtures
      • Custom fixtures are used for certain products during the annealing process to protect products, provide regular placement for robotic pick and place assemblies, and to ensure that heat distribution is occurring evenly while in a conveyor annealing oven. .
    • Indexing Belt
      • For proper product spacing for conveyor annealing ovens, indexing belts assure that proper belt load is occurring, with optimal heat distribution and airflow, and are compatible with robotic pick and place assemblies.
    • Post Process Cooler
      • Especially important in annealing batch ovens, post coolers cool ambient air and filter it from the oven chamber to begin reducing the temperature at a controlled rate, ensuring that maximum stress relief and strength is retained for the annealed material, and it’s ready for handling as soon as possible.
    • Robotic Pick and Place Interface
      • Robotic pick and place interfaces streamline production and cut costs. Our interface can be as simple as specific fixtures for patterned pick and place, or through sensors that will notify the pick and place assembly when a product is ready.
    • Heat Curtains
      • For conveyor annealing ovens, heat curtains are critical to retaining heat and an even heat distribution for the annealing process.
    • High/Low Temp Alarm Sensors
      • Temperature sensors are a critical part of any conveyor or batch annealing oven.  The sensors will alert workers if temperature is not within optimal ranges, as will occur if a n oven hasn’t preheated enough, or a door has been closed improperly.
    • Infeed/Exit Feed Length Adjustment
      • Entry or exit conveyor extensions are possible from lengths as fort as one foot, to as long as needed.
    • Fume Hoods
      • Fume hoods are a critical element to some plastic and composite annealing processes. A fume hood will capture fumes or volatiles and vent them. This is also a critical element to vapor heavy annealing which may inhibit heat transfer in the oven chamber.
    • Emergency Stops
      • Emergency stops are especially important on conveyor industrial ovens where moving parts can tangle with clothes or product if used improperly. Our emergency stops can be tailored by function, look, and location to meet your preferences.
    • Auto Shutdown/Start Up
      • Automatically activating and deactivating our ovens just before and after a shift ensures that productive time is not lost warming the oven and a failure to manually shut the oven down will lose you valuable energy and unnecessary wear and tear.
    • Digital Belt Speed Control
      • Setting belt speed digitally is a great way to make sure that the process is occurring at a precise and measured rate for accurate annealing and maximum efficiency. The speed can be set in either feet/meters per minute, or time the product spends in the chamber.
    • Material and Product Spreaders
      • Maintaining the proper spread and arrangement of materials and product in an annealing oven is critical to even heat distribution and air flow in the heating chamber.
    • Lockout Controls
      • Avoid improper usage of your annealing oven with security panels that keep sensitive controls from being used by anyone that isn’t qualified.
    • Belt Direction
      • Belt direction on conveyor models can be set to go either direction. On models with twin conveyors, the belt direction can be set to match or go in opposite directions.
