RoHS compliant black Zinc Nickel plating finish...
mphenol Ltd launched a new RoHS compliant plating finish last year and has now announced MIL-DTL- 38999,
A Series III, Approval, Class Z
connector manufacturer to achieve this success.
the first UK QPL
(qualified product listing) provides additional validation and certification over and above existing customer and programme approvals. In addition, Amphenol is the first corporation to provide multiple site qualifications with manufacturing in the UK and in the US. To be displayed at the forthcoming DSEi exhibition in London will be new Approved and RoHS compliant plating alternatives to Cadmium. Black Zinc Nickel plating is now offered on a wide variety of connectors and accessories including MIL-DTL-38999 and proprietary MIL-C-26482. This conductive and non-reflective finish is approved for 500hrs salt spray endurance and is fast becoming the new defence industry standard. Until recently, Cadmium plating has been the industry preference for aeronautical and defence applications due to its exceptional environmental and electrical performance. Despite an exemption in RoHS legislation allowing the use of cadmium in military applications, for several years now manufacturers have sought to reduce its use but have had to accept compromised performance as a consequence.

Spirol’s pin insertion technology provides solution for surgical tool manufacturer
S
pirol Industries has come to the assistance of a manufacturer of surgical tools looking for a means to automatically install a miniature pin, less than ø2 mm outside diameter and 10 mm long.
The pins were proving very difficult to
manipulate by hand and to meet specific clean room process specifications, Spirol recommended instead the use of a standard Pin Insertion machine, customised to meet the specific application needs of the customer. The pin to be inserted would ultimately be used in the human body and therefore there were strict cleanliness requirements to prevent any risk of contamination. For example, the pin could not come into contact with epoxy paint or steel during the installation process. Therefore all the parts of the Spirol Pin Insertion machine which would be in direct contact with the pin had to be manufactured from a specific list of materials and finishes. Inert (300 series) stainless steel, and Delrin® TM polymer was used for all machine components that came in direct contact with the pin. Electro-less nickel plating and white epoxy paint were employed in all other non-contact areas. The machine also provided an operator interface for a functional work station in the assembly environment. An Allen-Bradley® Touch Screen HMI was integrated in place of conventional buttons and switches, and an ergonomic adjustable table was provided to mount all machine components and to provide operator comfort.

Advertorial
new two-part repair paste system from diversified technology company 3M can extend the life of valuable rubber-based assets and provide cost and time savings when compared with
replacements. Scotchkote Urethane Elastomer 80XRG 539 from 3M is an elastomeric repair system for rebuilding and resurfacing rubber components including conveyor belts, rollers, gaskets and off road tyres, with a fast curing time to return equipment to service quickly. The two-part formulation is supplied as a convenient kit, which contains a primer and catalyst along with the easy-to-mix base and activator components. Providing a highly flexible repair with 250 per cent elongation and good cold vulcanising capabilities, the product is suitable for heavy duty applications. Recently trialled on the repair of a conveyor belt which had suffered severe abrasion damage at a Chilean copper mine, Scotchkote Urethane Elastomer 80XRG 539 allowed the belt to be returned to service within only 30 minutes, avoiding the costly downtime associated with conveyor replacement. Following that successful initial trial, the Chilean mine has started to place regular significant ongoing orders for the product.

production stoppages for circlip maker
A
BB variable-speed drives have helped a manufacturer of circlips cut production stoppages from typically three a week to none, as well as saving £11,000 a year in energy costs. Cirteq, based in Keighley, West Yorkshire, is one of the UK’s leading manufacturers of circlips. The company buys raw, unshaped wire and runs it through various processes before the circlip is cropped, shaped, heat treated and finished. One of the first operations in the manufacturing process is to shape and draw the raw wire. The machine used to perform this operation originally employed a very early type of DC variable-speed drive (VSD). The two main DC motors on this machine drove the shedding drum (the master drive) and the mill stand (the slave or follower). Used to shape the wire, these are controlled via a dancing arm that maintains tension in the drawn wire. The third motor, an AC motor, is used for the take-up or coiling drum and was controlled via an eddy current drive. These motors and controls were becoming difficult to maintain, were inefficient and were unreliable.
