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.

Porsche Classic begins supplying classic parts from a 3D printer

For collectors of rare classic cars, the unavailability of spare parts can quickly lead to problems. In the worst-case scenario, the car may even be forced out of action -- just sitting in a garage and maybe looking pretty.

Porsche Classic, the division of Porsche dedicated to classic vehicles, is developing a solution to this problem: producing extremely rare parts that are only needed in small quantities using 3D printers.

All parts that are produced using the 3D-printing process meet the requirements in terms of absolute fidelity to the original specifications, both from a technical and a visual perspective.

The Porsche Classic stable currently includes some 52,000 parts. If a certain spare part is no longer in stock or if stock is dwindling, the part is reproduced using the original tools. For larger quantities, production may require the use of new tools. But ensuring a supply of spare parts that are only required in very limited numbers sometimes poses a major challenge, even for the experts. Producing small batches using new tools would be largely inefficient and incredibly expensive. Nonetheless, before embarking on a project to produce a particular component, Porsche Classic always evaluates various manufacturing processes and the price that is willing to be paid.

As the quality of "additive" manufacturing processes continues to improve with generally decreasing costs, this new form of manufacturing presents an economic alternative for the production of small quantities. Say, for example, the release lever for the clutch on the 1983 Porsche 959 is no longer available. This component, made from grey cast iron, is subject to very high quality requirements. But it is in very low demand, because only 292 of these 450-hp super sportscars, notable for their aerodynamically optimized bodies featuring a rear wing integrated in the bodyshell, were ever produced.

The only manufacturing process worth considering would be selective laser melting. To manufacture the release lever, a layer of powdery tool steel less than 0.1 mm thick is applied to a processing plate in a computerized process. In an inert atmosphere, a high-energy light beam then melts the powder in the desired locations to create a steel layer. Thus, the complete three-dimensional component is produced, layer by layer.

Both the pressure test with a load of almost 3 tons and the subsequent tomographic examination for internal faults were passed by the printed release lever with flying colors. The practical tests -- with the lever installed in a test vehicle coupled with extensive driving tests -- confirmed the impeccable quality and function of the component.

Due to the consistently positive results received to date, Porsche is currently manufacturing eight other parts using 3D printing. The parts in question are steel and alloy parts produced using the selective laser melting process. Plastic components are manufactured using an SLS printer. SLS stands for selective laser sintering, a process where the material is heated to just below melting point and the remaining energy is applied through a laser to fuse the plastic powder at a selected point.

All parts are subject to the quality requirements of the original production period as a minimum, though they usually meet higher standards. Accuracy in terms of size and fit is ensured by performing tests with the part installed. Depending on the area of application, plastic parts made of various materials -- as in the original -- must be resistant to oils, fuels, acids, and light.

Porsche Classic is currently testing whether 3D printing is suitable for the production of 20 other components. Key benefits are that the three-dimensional design data or a 3D scan of the component is a sufficient basis to commence production, and that the components can be produced on demand if needed, thereby eliminating tool and storage costs.

Porsche classic car owners also get the parts quite quickly, so they can get their slick rides out of the garage and on the road faster.
