New Low-Profile Retaining Rings
Smalley Hoopster® Rings fit into shallower grooves than regular snap rings or retaining rings. Where retaining rings once were not an option because of groove depth, the low profile, precision circularity & small radial size allow Hoopsters to be unobtrusive components, ideal for thin wall tubes. Stocked from 3/8"-3" in carbon & stainless steel.

Resin selection: Check the data sheet
Whether you realize it or not, when you design a molded plastic part you are working at two levels. On the macro level you are creating a shape -- simple or complex -- that meets a variety of needs. At the same time, you are designing at the molecular level by your choice of resin or resin blend.

Heavy-duty pivot bushing

igus has launched a new, heavy-duty plastic bushing that can withstand radial loads up to 11,023 lb/in2. Injection-molded, self-lubricating and maintenance-free iglide Q2 bushings are made from a completely new material blend that performs up to five times better than any other plastic bearing material the company currently offers. An iglide plastic bushing material exists for almost every application scenario -- even chemical-exposed, dirty, underwater, high-load, or high-temp applications. These bushings may well become your new go-to solutions for heavy-duty jobs. Contact sales@igus.com for iglide Q2 specs.

Engineer's Toolbox:
How glass tapes improve thermoplastic composites is 2012 SPE Best Paper award winner

Ticona Senior Applications Engineer Duane Emerson was presented the Best Paper award at the Society of Plastics Engineers (SPE) Automotive Composites Conference & Exhibition this past September. "Using unidirectional glass tapes to improve impact performance of thermoplastic composites in automotive applications" describes a study conducted by Ticona that looked at methods to increase stiffness/strength and impact resistance of an automotive underbody shield (UBS) by using continuous strand, unidirectional (UD) glass-reinforced thermoplastic composite tapes to produce woven fabrics and tailored blank laminates.

Foam tape replaces messy liquid sealant for OEMs
Pres-On has introduced PF-1400 low-density, closed cell polyethylene foam tape. A clean, waste-free alternative to liquid sealant, this industrial-grade tape offers excellent weatherability in a wide temperature range (0 to 140 degrees F), making it ideal for the assembly of doors, windows, and cars, as well as for contractors who install HVAC equipment. PF-1400 provides long-lasting sealing, insulation, sound dampening, and cushioning. PF-1400 is coated on one side with a high-tack pressure-sensitive rubber adhesive protected by a paper release liner. The adhesive will bond to virtually any clean substrate, including irregular surfaces where it conforms to shape a positive seal.

The easier way to optimize your gear designs
Developed by leading experts in gear design, EXCEL-LENT software from Excel Gear provides a quick-and-easy way to optimize your gear designs with minimal input. Users can optimize rack-and-pinion, spur, helical, internal, external, and circular pitch gears in English or metric units. The gear/gearbox design software quickly determines product parameters for various applications, saving hundreds of engineering hours. This software has been written by engineers who also design and manufacture gears for their own use. Video is on right-hand side.

BONUS FUN: Playable Tetris pumpkin is Halloween smash
Pumpkin "hacker" Nathan Pryor is the creator of Pumpktris, a fully playable version of Tetris built into a real pumpkin using 128 LEDs for the display and a joystick-stem game controller. As reported on CNET, "Pumpktris took 12 hours of work, 256 pieces of heat-shrink tubing, and 313 solder joints to complete. So far, the top score is 9,800 points." A link to Pryor's instruction page is under video.
