New ‘pin and keeper’ quick-assembly
sign fastening system

The Micro Plastics sign fastener is designed for rapid assembly and disassembly of a sign or other panel to its support structure. The reusable fastener was designed to fit a hole diameter of 5/16 in. to 3/8 in. (8 mm to 9.5 mm) and can be used to fasten two pieces together with total panel thickness from 1 in. to 1.64 in. (25.4 mm to 41.6 mm). Simply squeeze the keeper together and slide onto the pin, then release the keeper. Molded from impact-resistant and UV-stabilized nylon 6/6, the sign fastener is designed to withstand the elements in outdoor applications.

Metal Bellows for Corrosive Media
BellowsTech edge welded bellows provide the most flex in the smallest amount of space and allow for flexibility in axial, angular and parallel offset motion. Metal bellows technology is employed in sub-sea and down hole applications with high temperatures, high pressures and corrosive media, all of which BellowsTech can customize its bellows to accommodate.

Plastics parts design tip: Cut to the bone
Plastic is inherently light, generally economical, and relatively easy to form. But that doesn’t mean that it can’t, with thoughtful design, be lighter still and even more economical, all without sacrificing performance or complicating manufacturing.

Measure and calculate the cost of energy waste

The new Fluke 430 Series II Power Quality and Energy Analyzers use a patented algorithm to measure energy waste and quantify its cost. This technology can help facilities reduce electrical power consumption and improve the performance and lifespan of electromechanical equipment by providing the ROI justification to mitigate power quality distortion. Electrical engineers, technicians, and electricians can assess the financial impact of new energy-efficient lighting, motor controls, and HVAC systems. Available from Newark element14.

Test the impact of motion behavior on iPhone, iPad
Autodesk ForceEffect Motion is a new, no-cost mobile simulation app for developing and testing mechanical systems with moving parts (scissor lift, windshield wipers, automobile engine, robotics, etc.). You start by importing an existing image or creating a freehand sketch and adding functional mechanical joints, actuators, constraints, and supports. Tap objects to select, move, rotate, and scale. Real-time solving capabilities provide immediate feedback on the system’s performance, which you can then print, email, or view as a results report on your iPhone, iPad, iPod Touch or any other device with an HTML-enabled browser. Also check out Autodesk ForceEffect, a simulation app that lets users calculate forces on a static object. Both available in the Apple App Store.
