White paper on Undercuts and Through-Holes
In the world of plastic injection-molded parts, indentations, through-holes, and other features that are not formed in the direction of the mold opening and closing could act as undercuts in a two-part mold. Designers using rapid injection molding can address these challenges in a variety of ways, including side-action cams, sliding shutoffs, pickouts, and bumpoffs. In this issue of Designing for Moldability, from Protomold, we discuss these techniques.

Rogan Liquid Silicone Rubber Molding Capabilities
Rogan Corporation, a full turnkey contract manufacturer of plastic components and assemblies, specializes in producing injection molded Liquid Silicone Rubber (LSR) components. The company is one of a few select manufacturers that also offers Bondable Liquid Silicone Rubber (Bondable LSR) overmolding that is injection molded directly to plastic or metal parts, creating a single integrated component. Utilizing LSR's heat/chemical/shock/vibration resistance and sound dampening, design opportunities include integral seals and gaskets for waterproofing complex geometries and electronic interconnects, integral membranes, diaphragms, valves, and switch covers.

A new state-of-the-art Class 100,000 clean room enables Rogan to meet the increasing demand for LSR molding and assembly.

Magnetic gears get 3D sim for direct-drive, in-wheel electric motors
An innovative electromagnetic simulation tool is speeding the commercialization of a breakthrough direct-drive technology for electric vehicles by U.K.-based Magnomatics. Called the Pseudo Direct Drive, this new form of traction motor offers such an exceptional torque density that it can even be packaged within a vehicle's wheel.

Machinery monitor sends text messages

Predictive Sensor Technology's Wireless Type K Thermocouple Transmitter (PST-TCK) alerts the user via text or email when pre-set temperature targets or limits are reached. This super-smart wireless monitoring system helps facility managers to "know before it goes." It also monitors and saves the condition history of the process to verify quality or enable adherence to manufacturing requirements or standards. Temperature monitoring is especially valuable in evaluating conditions of motors, pumps, bearings, and gearboxes.

Wire and harness protection gets colorful

Micro Plastics has added color to their polyethylene and nylon lines of wire-routing split loom. All six of the standard sizes (1/4, 3/8, 1/2, 5/8, 3/4, and 1 in.) are available in orange, which is especially great for safety. Red, yellow, and green are other options. Organizing cables and managing cords into color-coded bundles never looked so good.

Tough PLA alloys provide up to 40% biocontent

New Terraloy 70000 Series polylactic acid (PLA) alloys from Teknor Apex enable manufacturers of electronic housings and other components to incorporate substantial amounts of bio-based content in their products without sacrificing the essential mechanical and thermal properties provided by engineering thermoplastics (ETPs). These compounds provide similar or greater strength, stiffness, and heat distortion temperature in comparison with standard polycarbonate (PC), ABS, and PC/ABS blends.
