Former Standard Aerospace

This plant is one of several machines acquired during Standard Aerospace's reorganisation of one of their manufacturing facilities in the UK.
Their worldwide reputation for quality is reflected in the machinery and maintenance of their manufacturing plant.
Many of these machines include features that are necessary for the manufacture of aircraft components,
but can provide a benefit to any industry.


Common Heat Treatments That Use Industrial Ovens & Furnaces

Heat treatment is a controlled process of heating and cooling materials in order to improve its properties, performance, and strength typically made up of three main steps. Firstly heating the metal to a specific temperature, soaking or maintaining the specific temperature for a certain amount of time, and cooling to a suitable rate following prescribed methods.

There are seven main techniques used for the heat treatment of materials, and all affect material in different way. These techniques are:

  1. Normalising
  2. Annealing
  3. Tempering
  4. Hardening
  5. Ageing
  6. Stress Relieving
  7. Carburisation

Control Features of Your Industrial Oven/Furnace

Many of today's oven/furnace controllers feature multiple screens and options for the operator to adjust to their process, so understanding each of these controls could make the difference in in perfecting your heat process.

The most important features frequently seen on a control panel include:

  • On/Off Microprocessor-Based Controller – An on & off heating system to maintain the set temperature.
  • PID (Proportional Integral Derivative) Controller – An advanced heat output system to maintain a tight temperature uniformity.
  • Digital Process Timer – A timer to set the time length of the process.
  • Data Logger – Record the history of previous processes.
  • Single Setpoint Controllers – Control the rate of temperature increase & decrease inside the oven chamber.

For more information on each of these features and more, check out our article Essential Features of Industrial Ovens.
