One-part epoxy changes from red to clear under UV

Master Bond UV15RCL is a low-viscosity, cationic-type UV-curing system with a special color-changing feature. The red material changes to clear once exposed to UV light, indicating that there is UV light access across the adhesive material. Although this change in color from red to clear does not indicate a full cure, it does confirm that the UV light has reached the polymer. This epoxy is an excellent electrical insulator. UV15RCL adheres well to metals, glass, ceramics, and many plastics, including acrylics and polycarbonates.

SPIROL Press-N-Lok™ Pin for plastic housings

The Press-N-Lok™ Pin was designed to permanently retain two plastic components to each other. As the pin is inserted, the plastic backfills into the area around the two opposing barbs, resulting in maximum retention. Assembly time is quicker, and it requires lower assembly equipment costs compared to screws and adhesives -- just Press-N-Lok™!

What can you secure with a retaining ring? 20 examples

From the watch dial on your wrist to a wind turbine, no application is too small or too big for a Smalley retaining ring to secure. Light to heavy-duty loads? Carbon steel to exotic materials? No problem. See how retaining rings are used in slip clutches, bike locks, hip replacements, and even the Louvre Pyramid.

Load fasteners with integrated RFID

A crane, rope, or chain may be required when something needs lifting -- plus anchoring points on the load. JW Winco offers a wide range of solutions to fasten the load securely, including: lifting eye bolts and rings (with or without rotation), eye rings with ball bearings, threaded lifting pins, shackles, lifting points for welding, and more. Some, such as the GN 581 Safety Swivel Lifting Eye Bolts, even have integrated RFID tags to clearly identify specific lifting points during wear and safety inspections and manage them digitally and without system interruption.

Couplings solve misalignments more precisely with targeted center designs

ALS Couplings from Miki Pulley feature a simplistic, three-piece construction and are available in three different types for more precisely handling parallel, angular, or axial misalignment applications. The key feature of this coupling design is its center element. Each of the three models has a center member that has a unique and durable material and shape. Also called a "spider," the center is designed to address and resolve the type of misalignment targeted. Ideal for unidirectional continuous movement or rapid bidirectional motion.

What is 3D-MID? Molded parts with integrated electronics from HARTING

3D-MID (three-dimensional mechatronic integrated devices) technology combines electronic and mechanical functionalities into a single, 3D component. It replaces the traditional printed circuit board and opens up many new opportunities. It takes injection-molded parts and uses laser-direct structuring to etch areas of conductor structures, which are filled with a copper plating process to create very precise electronic circuits. HARTING, the technology's developer, says it's "Like a PCB, but 3D." Tons of possibilities.

Dollar for dollar and ounce per ounce, new steels clearly outperform competing materials for automakers

An increasing number of recently published studies about advanced high-strength steel (AHSS) reveal that it has become the lightweight automotive material that best addresses society's need for reduced greenhouse gas emissions, without compromising safety, performance or affordability, according to Ron Krupitzer, vice president, automotive market, Steel Market Development Institute, a business unit of the American Iron and Steel Institute.

The development of AHSS grades has been driven by the ever-increasing challenges faced by automakers, such as crash performance requirements, the need to reduce vehicle mass for fuel efficiency, and the need to enhance formability to manufacture high-strength parts.

"The advanced grades are relatively new to vehicle design and are significantly different from the conventional steels they replace," Krupitzer said. "The lightweighting capability of AHSS results from their unique combination of strength and ductility. These attributes are developed by creating specific microstructures through precise and tightly controlled steelmaking processes. The results are lightweight automotive designs that are cost effective with low emissions that also provide unmatched safety performance."

Below are some key advantages of AHSS:

Safety and durability performance

  • As shown in WorldAutoSteel's recent FutureSteelVehicle (FSV) study, using today's design optimization tools, a steel body structure with 35% weight savings can meet or exceed all safety requirements.
  • Steel remains the dominant material for automotive bodies and safety cages.
  • Consumers value the safety benefits of steel. When asked which automobile components protect them most, the top three choices by consumers were seat belts, steel frames (the steel safety cage) and steel side-impact beams (placed inside car doors to better protect passengers in side-impact collisions).

Sustainability

  • Steel is recycled more than all other materials on the planet combined, with an extremely high overall recycling rate. Recycling of automotive steel can top 100%, as the cars being recycled may be heavier than new models.
  • Because it is 100% recyclable, steel used in today's cars can help automakers reduce the carbon footprint of tomorrow's vehicles.
  • Automobiles are recycled more than any other consumer product, with nearly 100% of vehicles being recycled for their iron and steel content. In 2008, more than 14.8 million tons of steel were recovered for reuse from scrapped automobiles.
  • Life cycle assessment (LCA) is an established method of accounting for total greenhouse gas emissions associated with products like automobiles and determines the carbon footprint of products. Steel is the only material that reduces greenhouse gas emissions in all phases of a vehicle's life: manufacturing, driving, and end-of-life.
  • LCA shows that steel, which currently makes up about 60% of the average North American vehicle, generates fewer emissions than other automotive body materials; therefore, steel-intensive automobiles will continue to be the overall lowest-emitting vehicles on the road.
  • The use of AHSS reduces a vehicle's structural weight by as much as 25% (35% with the FSV) and can cut total life-cycle CO2 emissions by up to 15% more than any other automotive material, according to a WorldAutoSteel LCA study.

Affordability

The Massachusetts Institute of Technology study "Process Cost Modeling: Strategic Engineering-economic Evaluation of Materials Technologies" and related cost models identify alternative materials to be at a significant cost disadvantage for all aspects of the body-in-white manufacturing process. For example:

  • In raw material costs, aluminum is three times more expensive than steel;
  • In conversion costs, aluminum is two times more expensive than steel;
  • In assembly, aluminum is 20% to 30% more expensive than steel; and
  • In total, an aluminum structure is estimated at 60% to 80% more expensive than a conventional steel design.
  • Optimized steel body structures using AHSS can be constructed at no significant additional cost relative to a conventional body structure.
