Clever! Indexing plungers with chamfered pins

JW Winco has developed a new type of indexing plunger -- GN 824 -- that can independently latch into edges and grooves. This is made possible by a chamfered plunger pin. When the chamfered pin encounters a raised latching geometry, it retracts and then springs back out again once it reaches the latching point. This new indexing plunger can be ordered with axial thread for fastening and a black plastic knob for operating the indexing plunger. In a clever design, the plunger pin can be adjusted by 360 degrees to ensure that it encounters the mating surface perpendicularly. This hardware is well suited for transport frames, mechanisms, or covers that need to be locked in place quickly and securely, especially without the need for manual intervention.

NEW! Aluminum Press-In Inserts for plastics

SPIROL is pleased to introduce a range of 2024 aluminum Press-In Inserts. Available in symmetrical (Series INS 50) and headed (INS 51) versions, the new aluminum Press-In Inserts line complements the existing brass line. Threaded Inserts are essential for reinforcing plastic components and provide a reusable thread within a bolted assembly. This ensures a proper seating torque and prevents the potential for plastic creep over time. These inserts are designed to be Pressed-In without heat and provide the lowest cost to install with acceptable joint performance for many applications.

When glass or plastic can't cut it: Transparent ceramics solve critical design challenges

Complex designs are still possible when grinding and polishing Fused Silica or Sapphire. Ceramic properties such as wear, abrasion resistance, and strength of these optical materials can be a designer's dream solution when high temperatures or severe environments rule out standard optical glass or plastic. INSACO is a machine shop specializing in ultra-hard and extreme materials.

New contactless link magnetic couplings use magnetic field to transmit torque

Miki Pulley Magnetic Couplings are shaft couplings that transmit torque from one shaft to another using a magnetic field instead of a physical or mechanical connection. These Magnetic Couplings are non-contact and rely on the attraction and repulsion of magnetic poles to generate rotational power. The full product range can withstand significant misalignments and are silent, vibration-free, and do not generate thermal conduction. Design advantages include configurations that are versatile for use in various engagement angles and installations. Max transmittable torque is adjustable.

CNC machining: How to avoid high costs on thin walls

Parts that are light and strong are crucial to nearly every industry. To achieve better performance without risking part failure, parts must maintain a specific wall-height-to-thickness ratio and wall-height-to-length ratio. Additionally, some geometries and supports can support thin walls to achieve a lighter component weight. Dive deeper into the cost drivers behind CNC-machined thin walls in this Xometry design-for-manufacturing article.

Ford shows off giant 15-ft-long airbag curtain for Transit passenger wagon

What's behind Ford Transit's curtain #1?

Let's hope you never find out.

The all-new 2015 Ford Transit 15-passenger wagon features the industry's only five-row side-curtain airbag.

Part of Ford Motor Company's Safety Canopy System, this jumbo airbag is designed to help provide enhanced head and neck protection in rollover and side-impact crashes.

The airbag measures close to 15 ft long and 3 ft tall, with a volume of 120 liters. By comparison, a side-curtain airbag for a sedan like Ford Fusion is approximately 6.8 ft long and 2 ft tall, with a volume of 42 liters.

In a crash situation, a series of sensors detects the impact and triggers two of the industry's largest inflators to fill the entire airbag with stored gas in a fraction of a second. The inflators fill the bag in a pattern engineered to manage the direction of bag deployment and control cushion thickness throughout the length of the bag. The airbag is made of a coated, polyester-based fabric that holds the gas, so the bag remains inflated for several seconds.

The single-bag design -- in conjunction with tethering and the vehicle's B, C, and D pillars -- helps keep the curtain supported when deployed.

Ford developed the five-row side-curtain airbag in cooperation with TRW Automotive, a global supplier of active and passive safety systems.

"This airbag technology is unique in its purpose, which is to help provide protection across five rows of passengers in a cabin that is more spacious than the more traditional light-duty vehicle," says Norbert Kagerer, vice president, Occupant Safety Systems Engineering for TRW Automotive. "The stringent customer and industry regulatory requirements for airbags called for developing a system that provides appropriate occupant protection in a smart package."

Side-curtain airbags are standard on the Transit wagon, which is available in three roof heights, two wheelbases, and three body lengths. The high-roof, long-wheelbase wagon seats as many as 15 people and provides as much as 65.2 in. of headroom. The 15-passenger extended-length Transit wagon also boasts best-in-class cargo capacity (100.5 cubic ft) behind the last row of seats.
