In order to meet current weight-reduction constraints, aluminium wire is being used extensively and increasingly in the latest generation of aircraft. To give an idea of the significance of the issue, an A380 aircraft, manufactured by Airbus, requires over 500km of wires and cables of various kinds, and each section must be clearly identified in order to facilitate maintenance.
Further to requests from Airbus, Laselec has designed and developed a specific process for the marking of aluminium cables that is perfectly adapted to their characteristics. Laselec has a proven track record in the field, having successfully developed the first-ever system for stamping and identifying cables with the help of UV-laser technology, as early as 1989.
The latest technology developed by Laselec consists in a pre-marking of the spots by laser. The spots need to be positioned with the utmost precision in order to guarantee the safety of the crimping process. The key issue is that, on this type of aluminium cables, the contact points are totally leak-proof, without any openings that would enable the operator to check, by the end of the process, that the operation has indeed been carried out correctly.
At present, cabling companies use ‘felt-tip’ markers. As Eric Dupont, CEO of Laselec, explains: "The main disadvantage of this manual method stems from the imprecise and non-permanent nature of the resulting markings, which precludes any verification, after the event, of the crimping operation. Pre-marking the cables with laser-printed dots that are positioned with great precision solves these problems and, thus, guarantees the security of the operation.”
The novel process for the marking of aluminium wires, which has resulted in the lodging of several patents by Airbus and Laselec, has been approved, and should shortly be deployed by wiring and cabling companies across the aerospace industry.
The use of a laser system guaranteeing a permanent marking solution that does not damage the insulator represents a genuine technological breakthrough in the cable and wire marking sector. Widely used in both civilian and military programmes, this technique has proved very successful in various sectors. This is particularly true of the automotive industry, for top-of-the-range, competition and rally vehicles.
Laselec has also designed a sample tester, the MT 200, in order to verify the UV markability of cable and wire types currently under development, and to carry out periodical inspections of the cables (or wires) during production. The new EN 4650 standard underlines the manufacturer’s responsibility for the composition of wires and their various characteristics, which must remain unchanged after undergoing laser marking.
More than ever before, the MT 200 is emerging as a vital tool for verifying the suitability of the contrast level under the laser irradiation conditions applied by the users. The COMET system completes this range of equipment, offering the possibility to check the contrast of the markings once they have been applied. The software integrated into the COMET system performs the real-time analysis of the data obtained from a digital camera and a dual optical-fibre sample lighting system.
With over 80% of its turnover generated internationally, Laselec is focusing extensively on Asia and on the American market in 2011.
Laselec has been represented in India since 2004, and equips some of the largest Indian prime manufacturers, including HAL. A new site will be set up in the Asia-Pacific region this year, with stocks of spare parts stored in ‘service stations’ strategically located within easy reach of the main users.
Laselec is well-established on the American continent, where the company provides its clients with high-quality products and customer service from its main facility in Dallas (Texas). Laselec’s US team will be attending four trade shows in 2011.
The latest products and technologies developed by Laselec will be showcased at the following trade shows in 2011: from 9 to 13 February, at AERO INDIA in Bangalore (India); from 5 to 8 March, at HELI EXPO in Orlando, Florida (USA); from 17 to 20 April, at the Army Aviation Association of America/Quad-A in Nashville, Tennessee (USA); from 10 to 11 May, at a trade event held at Thai Airways Technical Department (Thailand); from 18 to 19 May, at the Wire Processing Expo in Milwaukee, Wisconsin (USA); from 20 to 26 June at the Paris Air Show in Le Bourget, north of Paris (France); and, finally, from 10 to 12 October, at the NBAA in Las Vegas, Nevada (USA) .
