Altec Launch New Specialist Coating Facility

Date Added 12/06/2014

Altec Engineering Limited has announced the launch of a new Specialist Coatings facility, located in Sedgefield, County Durham. This unit has been set up to support the continued growth of the CNC precision machining operations at the main Bowburn site, and meet the increasing demand for finished components from Altec’s aerospace, oil & gas and electronic sector customers.

The company has invested in a wide range of equipment and processes including Vibratory Trough Finishing and Shot Blasting to perform preliminary operations and generate the key face to which the surface coatings will bond.

Surface coatings offered by Altec at the new Sedgefield site include Alocrom 1200, used for general industrial work, electrical components and domestic appliances. Alocrom 1200 is also approved to DEF STAN 03-18 Certificate No. 031801 for use on aircraft components.  This process is ideal for coating all types of aluminium and aluminium alloys including high silicone pressure die-castings and is often used on aluminium when maximum corrosion resistance is required.

As an environmentally friendly alternative to Alocrom 1200, Altec also offers SurTec 650 that delivers excellent corrosion resistance and low electrical resistance. This non-toxic process provides excellent bare corrosion protection with or without paint, works extremely well on alloyed, cast and extruded aluminium and is suitable as pre-treatment prior to lacquering or powder coating.

Coatings are produced within generous dip tanks with a capacity of 600mm W x 1300mm L x 600mm H, and if required larger tanks can be manufactured in-house to meet customer specific needs.

In addition to the existing Alocrom1200 and SurTec 650 coating processes, Altec has also installed the equipment needed for Zinc and Manganese Phosphate coating.  Qualification trials, together with the process datasheets for these additional coatings, are currently being completed and once fully integrated within the company’s quality procedures, these new coating processes will also come on line in the near future. Altec’s offering on specialist coatings will be further enhanced in future with the Xylan and Hard Anodising processes.

Director Paul Lackenby commented “This new dedicated facility allows us to meet the increasing demand from our customers for finished parts, and provides the capacity needed to support the continued growth of our CNC precision machining operations. We are able to provide a rapid turnaround of high quality components whilst maintaining full control at all times, including the inspection and full process documentation procedures.”

Stringent quality controls, implemented on site within a dedicated laboratory clean area, include chemical titration checks and evaluation of coating weights, which is checked using calibrated precision scales. Calibrated electrical testing can also be carried out on components prior to dispatch if required. The business will continue to research new calibrated processes to ensure that the highest levels of process compliance and final quality are always achieved and are always repeatable.

This latest announcement follows other recent and major investments by the company in new machine tools and a £1.5M extension to the Bowburn site that is currently under way and on schedule to open in the Autumn of this year.

Altec has been in business for 36 years and has grown to become a highly successful and dynamic company offering a comprehensive range of services including Mechanical & Electrical Engineering, CNC Precision Machining and Special Purpose Machine Design & Build. The company operates within the Oil & Gas, Automotive, Aerospace & Space Science, Medical Science and Nuclear & Renewables sectors.
