Dörken exhibits its capabilities
Micro-layer corrosion protection systems are in use everywhere where modules and components need to be protected against corrosion and other influences. At the recent Hanover SurfaceTechnology trade fair, Dörken MKS-Systeme showcased these systems under the DELTA-MKS®
T brand.
he high frequency of business partners from throughout the value chain at Dörken’s stand during the fair was typical for its fair appearances. Representatives of the French car manufacturers were particularly interested in discussing the efficiency of the 2-in-1 basecoat DELTA-PROTEKT®
KL 105. The cost savings that this product represents are a particularly important factor for the currently weak French car market. The company was rewarded for its efforts with inclusion in all key French
specifications, such as those of PSA and Renault-Nissan, but also in other European markets such as Italy, at Fiat. Dörken points out that the top coat DELTA-PROTEKT®
VH 301.1 GZ has also developed positively and become well established. It
was the subject of attention amongst German automobile industry representatives in particular. The distinctive characteristic here is that a surface can be bolted against different backings, enabling the tribological premium top coat to set standards with regard to efficiency and quality. Launched on the market as recently as 2011, the top coat has now become firmly established with nearly all German OEMs – and without any teething problems reported. A further topic that has seized the attention of the automobile sector and its fastening experts in particular is the previously
unresolved problem of black surfaces. Attempts are still being made to find an efficient, economical solution in the field of zinc lamella that satisfactorily resolves both installation difficulties and corrosion protection. Dörken MKS-Systeme was able to present initial prototypes and discuss the situation with experts at the show.
Keighley Laboratories achieves Nadcap accreditation
The technical services division of Keighley Laboratories has achieved world-class Nadcap accreditation for a Materials Testing Laboratory (MTL), a status recognised by the majority of global aerospace primes as a mark of quality assurance excellence.
T
he UK based company also gained a coveted Merit grade, which rewards superior performance in Nadcap audits and reduces subsequent audit frequency. Accreditation has also prompted affirmation and prolongation of its Airbus approval, the aircraft
manufacturer having adopted the Nadcap programme for its global supply chain. As one of the few Nadcap accredited MTL facilities in the UK,
Keighley Labs has been successfully assessed for the evaluation of aerospace welds, tensile, impact and bend testing, metallographic and micro indentation hardness procedures, and specimen preparation and machining. Combined with UKAS accredited testing and certification to many international standards and Civil Aviation Authority approval of in-house weld specimen supervisors, this confirms the company as a centre of excellence for weld testing. “This is an important breakthrough for the company, since it raises
our profile and reputation within the aerospace industry and enables us to obtain greater recognition for our expertise in weld and materials testing,” said Debbie Mellor, managing director at Keighley Labs. “It helps us to retain existing customers within the Northwest Aerospace Alliance and beyond, establishes our technical credentials for fresh market opportunities in other industries and paves the way for further export business in weld testing and other special processes.”

‘Closed structure’ thread rollers
Videx Machine Engineering Ltd says that its VA-ES series of ‘closed structure’ thread rollers is a cost effective line of machines that are specially designed to roll high tensile fasteners at the utmost quality.
downtime. The VA-20-ES can be used to roll M10 Grade 10.9 screws at a rate of 250 – 350 parts per minute. Videx has also recently introduced its first
T
‘computerised match’ machine, which includes a screen and a fine-match system, allowing the operator to match the dies from the control panel without any tools. Once matched, the operator has a library of thread sizes from which they can choose the requested thread size and perform a changeover in minutes. The ‘closed frame’ enabled Videx to design and
sell a few thread rollers with longer die pocket, up to 300mm long. The new technology is also available on the Videx Dual-Spindle thread rollers, enabling users to straighten and thread pre-hardened long screws or thread and knurl.
he VA-20-ES machine offers low cost per threaded part, using a new type of coated thread rolling die which doubles the die life and results in fewer changeovers and less
