Temperature control technology from West Control Solutions is enabling Active Magnetic Inspection (AMI), a US company that treats and inspects fasteners for the aerospace industry, to improve traceability on its output.

AMI wanted to establish a process system that would earn accreditation from the National Aerospace and Defense Contractors Accreditation Program (Nadcap) and thus enable the company to strengthen its position in the aerospace fastener business. To meet this need, AMI’s systems were enhanced by temperature controllers from West Control Solutions.

AMI enlisted the services of RJ ‘Skip’ Schaefer of Titan Industrial Heating Systems, an expert in the design and construction of temperature-controlled manufacturing processes. Schaefer’s task was challenging as many points of control were required. These included two stress-relief ovens that each required the monitoring of 60 product containers. It was also necessary to establish a thorough quality system, including well-documented process instructions and complete records for all production lots, including time and temperature data, to meet the needs of the annual audit.

The CAL 9500P process controller was chosen as the front end for flexibility and profiling power. In order to satisfy Nadcap process data requirements, all of the instruments are tied to a central PC that runs Calgrafix process monitoring software.

Key benefits of product application

  • Schaefer said that in the 25 years he has been using CAL temperature controllers he can count on one hand the number of failures he has experienced.
  • With the new process system, every point is monitored and stored on a minute-by-minute basis. 
  • When the process system was inspected by Nadcap, the results were excellent and AMI was issued with its certificate, enabling the company to strengthen its position in the aerospace fastener business.
  • According to Schaefer, there have been zero flaws in the system. ‘That’s with two ovens: one with 36 controls and one with 34, both working 24 hours a day, seven days a week,’ he said.

Key products from West Control Solution include:

  • Temperature controllers (single-loop and multi-loop contollers)
  • Process controllers
  • Limit devices
  • Profilers and programmers
  • Digital indicators
  • Transmitters
  • Circular chart recorders (analogue and digital)
  • Paperless chart recorders

Controllers are available in 1/32, 1/16, 1/8 and 1/4 DIN sizes. There are also a number of DIN-rail-mounted controllers available. At the heart of all product designs from West Control Solutions is exact, accurate temperature control in easy-to-use products complemented with excellent reliability and durability.

West Control Solutions works with a global base of equipment manufacturers and end users. The products are ideally suited to challenging and tough environments such as industrial ovens, furnaces and kilns, plastics and extrusion. As the products offer excellent levels of precise control and accuracy together with being attractive instruments with strong aesthetic consideration during design they are often commonly used in laboratory, testing equipment and food and beverage applications.

The products are supported by a dedicated team of technical support specialists. The team has more than 25 years’ experience in temperature control instrumentation, specifically supporting products in industrial applications. This knowledge provides customers with complete peace of mind that they will be able to maximise the functionality available within the products even for the most complex of applications.

In addition to the core product offering there is also a customisation team that is available for those occasions where a custom controller will fit your requirements better than a standard product. In these cases, a comprehensive specification will be created, considering all requirements relating to the look and feel of the instrument, the format and functionality that is required. For the majority of customisation projects either a standard controller or a previous custom design can be used as the starting point for the bespoke design. This allows customers to benefit from reduced design and manufacturing costs, resulting in more customers to gain competitive advantage through unique designs and advanced functionality.
