MATERIALS:Lee Spring® introduces LeePTM Plastic Composite Springs, a revolutionary breakthrough in spring technology. LeeP is Lee Spring’s answer to increased customer requests for springs that combine the strength of metal with the special attributes of high performing engineered thermoplastics. After years of extensive engineering design and materials research by their expert technical team, Lee Spring developed these unique compression springs. LeeP springs are fabricated in distinctive formulations of Ultem* PEI resins. The company says it selected Ultem resin as the material of choice for LeeP because it meets or exceeds the criteria it set forth for developing this line. Ultem resin is produced by SABIC Innovative Plastics, a leader in engineered thermoplastic material solutions.
LeeP Plastic Composite Springs are stocked in a variety of standard sizes, each available in a “rainbow” of strengths formulated from different Ultem resins. The six increasing strengths are easily identifiable by distinct colors: red, orange, yellow, green, blue and violet, with violet being the strongest. In addition to its initial LeeP Stock Compression Spring offering, Lee Spring has developed the advanced technology to provide Custom LeeP Springs to meet customers’ most exacting requirements.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
