Printing conductor paths

Paul Boughton

Printed electronics are becoming ever more significant in industry. The term includes electronic applications manufactured by means of printing processes.

And at this year’s Hannover Messe (13th-17 April 2015), flexo printing specialists and full-service providers in the printed electronics segment, ContiTech and SAUERESSIG FLEXO together will be offering customers an easy means of access to this market.

Instead of printing ink, electrically conductive materials are printed, thereby producing RFID solutions, sensors, displays, or solar cells. The opportunities for cost-efficient, sustainable, and environmentally friendly production in flexo printing are far from exhausted, according to experts in the industry.

Meanwhile, ContiTech will be bringing numerous innovations to the 2015 trade fair, where it will have two stands this year. 

The corporate stand in Hall 6 (Stand F18), will feature process and materials expertise of the rubber and plastics specialist. 

At Stand B18 in Hall 25, the focus will be on products such as drive belts, hoses, hose lines and air spring systems. 

Other highlights will include the SafeTrap scaffolding hatch which has passed fall tests and is now being used for the first time by the company’s development partner ALTRAD plettac assco, one of Germany's leading one-stop suppliers of façade, modular, and mobile scaffolding systems.

The self-closing, flexible scaffolding hatch offers maximum safety. Whereas conventional solutions are flexible only to a limited degree, SafeTrap is based on a combination of an aluminium profile and a vulcanised rubber layer with fabric reinforcement.

Workers on scaffolding can open the hatch with their heads when climbing. This means that they do not have to put down tools, building materials, or other materials in order to open the hatch. The hatch then closes by itself or with a push from the worker's foot.

ContiTech uses its expertise in lightweight construction to develop applications where metal once dominated. For the first time, the bearings specialist has developed a transmission crossbeam from fibreglass-reinforced polyamide BASF Ultramid for the rear axle, which is used in the Mercedes-Benz S-Class.

The new variant is about 25% lighter compared with diecast aluminium versions, and represents a milestone in the use of polyamides in the chassis segment. It is used in Mercedes-Benz vehicle models with all-wheel drive – with the exception of the AMG range. The component boasts optimum strength, good NVH performance, and high crash-protection.

As a central component of the rear axle, it supports forces and torques of the rear axle transmission.

A new engine mount made of halogen-free plastic, fire-retardant up to 220°C, provides greater safety around the house. Among other things, it meets the requirements of the US fire protection standard UL 94 V0, which is identical in content to the European standards DIN EN 60695-11-10 and -20 and the Canadian standard CSA C 22.2.

The products on display in Hall 25 will include drive belts, hoses, hose lines, and air spring systems from ContiTech. ContiTech has broadened its range of eco-friendly drive belts marketed under the BlueConcept label. The label stands for environmentally compatible and healthful industrial applications. In the future, a timing belt will also be available for project business.

The CONTI SYNCHROBELT PIONEER contains no carbon black and is free of allergens, making it the alternative drive solution for the consumer goods industry. With the CONTI POLYROPE, ContiTech has made further developments to the flat belt technology that was introduced to the elevator industry in the late 1990s.

The CONTI POLYROPE is certified according to the 95/16/EC Lifts Directive, and offers numerous advantages over conventional steel cord. The coating is abrasion-resistant and resistant to hydrolysis, and has excellent traction characteristics – reliable power transmission is ensured even at maximum load.

The CONTI POLYROPE is available in widths of 25mm and 50mm and with both a flat and a ribbed rear side.

Fuel lines with electrically conductive liners have been used in series production in the automotive field for some time now. And this application is now becoming increasingly interesting for industrial vehicles as well – not least due to the relevant regulations in the US.

The conductive inner layer made from FPM (fluoropolymer rubber) prevents a static charge from forming at high flow rates, which – in the worst case scenario – could lead to flying sparks and the spontaneous ignition of the vehicle. The ultra-flexible fuel lines from ContiTech are suitable for gasoline, diesel, and biodiesel, and permanently withstand operating temperatures from -40°C to 160°C. Projects with sustained temperatures of 180°C are currently undergoing final testing.

The CONTI CLEANJET – FDA is the multi-purpose hose for the food industry and is suitable for both the thorough cleaning of machines and systems as well as for the hygienic processing of liquid foodstuffs containing oil and grease.

Thanks to a specialised, highly resistant rubber compound, the CONTI CLEANJET – FDA can even handle corrosive chicken fat.

The robust brand-name hose also reliably delivers hot water up to a temperature of 80°C and an operating pressure of 90 bar, which sets this high-quality universal hose apart from all other cleansing and food hoses available on the market.
