Flex thixotropic one-component dual-cure epoxy
Master Bond UV23FLDC-80TK is a moderate viscosity, cationic-type system that offers both UV light and heat curing mechanisms. It cures readily within 20 to 30 sec when exposed to a UV light source. The adhesive can also undergo a secondary heat curing for shadowed areas, typically curing in 60 to 90 min. The system's adaptability to varying depths and applications, such as encapsulation and bonding, enhances its versatility. Well suited for uses where low stress is critical. Learn more.

Identify and solve problems related to pneumatic filling when distributing particle foams in molds, even taking gravity and mold closing into consideration. Avoid those pesky air pockets. Learn more.
Best practices for making technical drawings
Ambiguities in technical drawings can cost extra money when a part must be redone or reworked, leading to unexpected project delays. It is essential to create clear technical drawings the first time around. Did you remember to include an isometric view if possible? Did you limit the number of hidden lines? Xometry lays out 14 tips that to help engineers create clear and professional manufacturing drawings. A solid review. Read the full Xometry article.
SPIROL's new video showcases their updated Model PR and Model CR Semi-Automatic Installation Machines for Pins, Alignment Dowels, and Bushings. The video demonstrates how to operate the machine, details standard features, and optional quality and error-proofing enhancements. More than 80% of the components in this installation equipment are standard, pretested, production-proven, off-the-shelf parts. This translates into faster delivery, greater reliability, and lowest cost for equipment of comparable quality. View the video.
Are fasteners over-torqued in your assemblies?
According to Mountz, if you currently use a click wrench for your bolting application, you should proceed cautiously because click wrenches are easily misused, which leads to over-torque events. Replacing a click-wrench with a Mountz FGC cam-over wrench helps prevent operator anomalies and over-torque occurrences, because a cam-over mechanism physically prevents the operator from over-torquing fasteners.

New technique provides breakthrough in ceramics 3D-printing technology

Researchers at HRL Laboratories, LLC, have achieved a new milestone in 3D-printing technology by demonstrating an approach to additively manufacture ceramics that overcomes the limits of traditional ceramic processing and enables high-temperature, high-strength ceramic components.
HRL's Senior Chemical Engineer Zak Eckel and Senior Chemist Dr. Chaoyin Zhou invented a resin formulation that can be 3D printed into parts of virtually any shape and size. The printed resin can then be fired, converting it into a high-strength, fully dense ceramic.
The resulting material can withstand ultra-high temperatures in excess of 1,700 C and exhibits strength 10 times higher than similar materials.
Ceramics are much more difficult to process than polymers or metals because they cannot be cast or machined easily. Traditionally, ceramic parts are consolidated from powders by sintering, which introduces porosity and limits both achievable shapes and final strength.
"With our new 3D-printing process, we can take full advantage of the many desirable properties of this silicon oxycarbide ceramic, including high hardness, strength, and temperature capability as well as resistance to abrasion and corrosion," says program manager Dr. Tobias Schaedler.
The novel process and material could be used in a wide range of applications from large components in jet engines and hypersonic vehicles to intricate parts in microelectromechanical (MEMS) systems and electronic device packaging.
