Curing Time of Polyurethane Matrix Resin Cut to Just One Minute

Where R&D competencies complement each other, outstanding development results invariably ensue. Henkel’s know-how in the field of polyurethane-based composite matrix resins and the expertise of KraussMaffei, one of the world’s leading makers of manufacturing and processing machinery for plastics, have proven to be a perfect match. The outcome: The curing time of matrix resin Loctite MAX 2 has now been reduced to just one minute. The significant improvement on the original goal of five minutes relates to a performance result achieved for the first time on a high-pressure dosing unit.

The result of the collaboration between Henkel and KraussMaffei Technologies: A lightweight component in the form of a cover for the central console, made from carbon fibers supplied by Zoltek impregnated by Loctite MAX 2 from Henkel. This cut-back in the curing time is a further breakthrough in the development of composite matrix resins for the manufacture of lightweight components in the automotive industry. Loctite MAX 2 is a recent Henkel development – a polyurethane-based composite matrix resin that cures significantly faster than the epoxy products usually employed for the resin transfer molding process (RTM). Moreover, due to its low viscosity, Loctite MAX 2 penetrates and impregnates the fiber material significantly more easily and less harshly than competitor solutions, enabling very short injection times to be applied.

Offering low weight combined with high strength, carbon or glass fiber-reinforced composite materials continue to gain in significance for the manufacture of motor vehicle components. Particularly for mass-produced automobiles, resin injection processes such as RTM predominate in the manufacture of these automotive composites. “And now, with Henkel’s matrix resin technology competence combined with the high-pressure technology of KraussMaffei, the production of these composites is destined to become even more cost-efficient and reliable,” says Frank Deutschländer, Global Market Manager Automotive at Henkel AG & Co. KGaA. With its otherwise extensive adhesives portfolio, Henkel is thus able to offer a complete and coherent system for the manufacture and integration of composite components in the automobile.

The primary goal of Henkel’s collaboration with KraussMaffei going forward is to achieve further reductions in the manufacturing cycle times of as wide a range of components as possible. “We are confident that, in the near future, we will be able to significantly further develop the high-pressure RTM process through our cooperation with Henkel,” says Erich Fries, Head of the Composites/Surfaces business unit at KraussMaffei.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications. The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications. “We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner E

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs. The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon. These power supplies have a very compact form factor with overall dimensions reduced by up to 25% from previous generations. The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs. Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these p

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference. The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection. The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.
