Three Waves of Nanotechnology

Quick, what's the smallest car you can think of? Your mind might leap to the Cooper Mini or the Mercedes-Benz SMART car. Or perhaps even a Matchbox toy car? But these vehicles are gargantuan compared to Rice University's single-molecule car, the world's first tiny nanocar. The entire nanocar measures just three to four nanometers across, making it slightly wider than a strand of human DNA. A human hair, by comparison, is about 80,000 nanometers in diameter.

Hardinge’s next generation Rotary Indexer is lean and mean

The evolution of the Hardinge 5C rotary system began in 1901 with the production of Hardinge’s first 5C collet. Hardinge introduced the 5C “threaded-nose” spindle in 1940 on a precision bench lathe. In the 1960’s they manufactured a 5C manual indexer using their threaded-nose spindle and collet closer design. Later the Hardinge 5C rotary system was manufactured based on their original 1960’s mechanical design. Today Hardinge takes the 5C indexing market to the next level with more accuracy, more spindle clearance, more axial load and more radial load with their 5C2 Rotary Indexer.

Lean Manufacturing Trims Leadtimes

Over the last decade, as molds have become more complex, so have the systems and components that are used in their design and build. The delivery and pricing pressure is on the manufacturers and suppliers—with quality a given. Hot runner and component suppliers are delivering their goods faster and less expensive; and leadtimes on these items have significantly shrunk. Below, a cross-section of market leaders in these sectors take a look at the past decade, and discuss present and emerging trends.
