How mobile equipment manufacturers benefit from using formed thermoplastic hoses

The proper assembly, installation, and specifying of the right hoses and tubing for the application are critical to the trouble-free operation of mobile equipment employed in construction, forestry, mining, and similar industries. This latest blog from Parker examines how formed thermoplastic hoses address these challenges and details how a skid-steer manufacturer reduced labor time and realized significant cost savings.

Inch-size mounting clamps with swivel ball joint

GN 784 mounting clamps with swivel ball joint from JW Winco allow precise and variable adjustment of the ball pivot within the rotation range. This is a particular advantage when adjusting scanners, cameras, lighting, monitors, etc. Thanks to the efficient clamping mechanism, only small amounts of torque on the clamping screw result in comparatively strong clamping pressure on the ball. This force is easily applied by the clamping lever.

Save time with Spirolox® retaining rings

Unlike die-stamped circlips, Spirolox retaining rings and constant section rings are coiled on edge to the exact diameter required. Spirolox rings have no protruding ears to interfere with mating components in an assembly and do not require special tools for removal or installation. Unlike traditional fasteners, retaining rings eliminate machining and threading, reducing costs and weight. Spiral retaining rings do not require special tools for removal and are supplied standard with removal notches for easy extraction from a groove. Smalley offers over 6,000 standard rings, which are readily available in both carbon and stainless steel. For more information, download the eBook. Visit Smalley.com to request a catalog and product samples, or contact one of Smalley's engineers with questions.


Polyplastics develops metal-resin bonding tech for automotive and electrical/electronics

Polyplastics (Tokyo), a global supplier of engineering thermoplastics, has developed an innovative technology for direct metal-resin bonding, a process that uses metal insert molding. Metal parts and resins are firmly bonded by introducing molten resin through injection molding to metal parts that have already undergone sufficient surface treatment. Metal-resin composites deliver the properties of metals (high rigidity, electrical conductivity) and engineering plastics (low density, electrical insulation). This technology has overcome the many factors that traditionally have had an adverse effect and prevented stable bonding. Polyplastics has a U.S. presence in Farmington Hills, MI.

Surface treatment available for strongest cast aluminum alloy

General Magnaplate Corp. has made an exclusive license agreement with the U.K.'s Poeton Industries for the Apticote A20X surface enhancement process, used for treating the innovative A20X aluminum alloy. A20X is MMPDS certified (as AA205) and is the strongest cast aluminum alloy available today, with strength properties comparable to 7000 series wrought material. A20X cast and additively manufactured parts are in production today for major aerospace customers. The AptiMag-X treatment enhances the surface of A20X parts, improving wear resistance, hardening, and finish. The agreement means that General Magnaplate will become the exclusive supplier of Apticote A20X, which they will brand AptiMag-X in North America. Licensed A20X foundries, additive manufacturing companies, and aerospace customers will be able to have parts treated with AptiMag-X at the company’s facilities in Linden, NJ, and Arlington, TX.

New bearings for high-speed applications

A clear trend in compressor and pump applications is to raise the power density by increasing the rotational speed. To fulfill this requirement, SKF has developed a new range of single-row angular contact ball bearings. The goals have been threefold: to increase the limiting speed by 40 percent, to reduce the noise levels, and to increase the robustness of the bearing in unfavorable operating conditions (shock loads, shaft misalignment, etc.). Apart from these, SKF is helping manufacturers to meet customer demands for even higher levels of energy efficiency and reliability.

What are the strongest adhesives for bonding titanium?

Master Bond’s labs recently tested the tensile lap shear strength of a variety of adhesives when bonding titanium to titanium. The surfaces were properly roughened and cleaned with acetone in preparation for the tests. Each of the 11 one- and two-part epoxies tested features different thermal, electrical, and chemical resistance properties that can make them more appealing for specific applications. Therefore, it’s important to consider the operational conditions before deciding that the system with the highest strength value is the best for the titanium bonding job.

New light and tough structural compounds

RTP Company has developed new light and tough (LT) Compounds, a series of thermoplastic compounds that weigh 5 to 10 percent less than typical filled compounds, but with equivalent mechanical properties and similar shrinkage values. LT Compounds are a fast and easy way to accomplish weight reductions in parts molded with glass fiber reinforcement without compromising performance or requiring modifications to existing tools. They are best used as lightweight alternatives when the goal is to minimize energy consumption or the amount of human effort required to use the part.

Alcoa reinvents the wheel alloy; lighter, stronger material coming in 2014

Alcoa, the inventor and a global leader of forged aluminum wheels, recently rolled out the most advanced aluminum wheel alloy in 45 years. The new material opens the door for lighter weight wheels at increased strength with the same corrosion-resistant characteristics as the industry standard, also made by Alcoa. Alcoa expects to introduce a new, state-of-the-art wheel featuring the alloy in early 2014.

Alcoa is rolling out the most advanced aluminum alloy for truck wheels in 2014, opening the door for lighter, stronger, corrosion-resistant wheels. Alcoa invented the forged wheel, shown here.

 

 

Unveiled at the American Trucking Association Management Conference & Exhibition in Orlando, Fla., in late October, the new lightweight alloy, called MagnaForce, is on average 16.5 percent stronger than the industry standard, Alcoa's 6061 alloy, in similar applications. Alcoa will use the material to manufacture wheels for commercial transportation, where lighter weight products that increase fuel efficiency are in high demand.

"Alcoa is making truck wheel history with our innovative aluminum material," said Tim Myers, president, Alcoa Wheel and Transportation Products. "No manufacturer has produced a wheel with an alloy superior to Alcoa's 6061 material. Our MagnaForce alloy opens the door to production of the strongest, lightest wheels to increase fleet payload, improve fuel efficiency and enhance sustainability."

Alcoa has been the industry leader since inventing the forged aluminum wheel in 1948 using an alloy it had developed for the aerospace industry. In 1968, Alcoa set the industry standard again when it launched its 6061 alloy for forged aluminum wheels. Alcoa's 6061 material provided a strong, durable alloy, resistant to corrosion, that is used to this day by all major forged aluminum wheel manufacturers. During that time, Alcoa's experts have continually met increasing demands for lighter weight wheels, engineering products that today are 10 lb lighter than wheels from 20 years ago, using the same alloy.

Alcoa's scientists and engineers at the Alcoa Technical Center (located outside Pittsburgh), the world's largest light metals R&D center, invented the MagnaForce alloy following two years of development.

Alcoa Wheel and Transportation Products is part of Alcoa's downstream business, Engineered Products and Solutions. Through the third quarter of 2013, Engineered Products and Solutions contributed 25 percent of the company's total revenues.
