Design Tips: 12 Essentials for Moldability
Ten years ago, we began publishing Protomold Design Tips to help product developers create better injection-molded plastic parts. We've covered materials, texture, draft, sink and many other design considerations. More than 100 tips later, we remain steadfast in our effort to continue informing designers and engineers in all areas of injection-molded part design. As a resource, we've gathered some of our most useful manufacturing advice from the past decade in a collection of essential tips.

Navy Research Lab builds satellite module to test sending solar power from space
What if you could capture solar power in space, then send it down to Earth? Engineers at the U.S. Naval Research Laboratory are attempting to do just that, building technologies with the aim to power a military installation or a city (even on a cloudy day, even at night) from space.

Image - Piezo motor technology: Questions answered
Piezo motor technology: Questions answered
There's a new kind of piezo motor in town, and it's got legs. The Piezo LEGS® rotational motor is a direct-friction drive that provides precise motion without any mechanical play or backlash. There are no gears or transmission, so changing the direction of the motion will introduce no error. The simple Piezo LEGS® motor is also extremely stiff. Find out the answers to frequently asked questions about this exciting new motor technology.

Basics of motion control:
How feedback encoder devices operate

Feedback is used in closed-loop systems in applications all over the world to control speed and/or position, and it has an important role in keeping equipment operating smoothly and accurately. Feedback is available in a variety of devices as well as models. It is important to understand how feedback operates, so the best benefits can be used in the application. This article reviews: open-loop vs. closed-loop applications, tachometers, Hall sensors, incremental encoders, absolute encoders, and resolvers.

Rolling bearings for industrial gearboxes
NKE Austria offers rolling bearings for industrial gearboxes that meet the efficiency and reliability requirements of a wide range of sectors, such as general machinery, mining, material handling systems, and heavy machinery. NKE manufactures over 3,000 different variants of bearings suitable for high radial loads and moderate to high speeds. Made from pure rolling bearing steel, they have an exceptional lifespan, while the raceways' high surface quality reduces the operating temperature and wear. The inner and outer rings of the cylindrical roller bearings can be fitted separately, simplifying installation. They can be ordered with short lead times through the main U.S. distributor Ritbearing.

Image - Fast and svelte 6-axis robots
Fast and svelte 6-axis robots
The new Epson C4 and C4L compact 6-axis robots feature faster speeds and more payload capability than the C3 models, while keeping the popular SlimLine design. These are some of the fastest compact 6-axis arms available in the industry. The slim body and compact wrist allow for the units to easily reach into confined and restricted work spaces from many angles with a smooth motion. The tight integration of powerful motors and amplifiers along with ultra-high-resolution feedback and superior controls provide unmatched motion performance, including higher acceleration and deceleration rates as well as advanced linear interpolated motion. They are ideal for small parts assembly, dispensing, lab automation, machine tending, material handling, packaging, and more.
