...multiple passes can be used to produce a forging in a single heat. This leads to substantial energy and labour savings compared with conventional forging. [Diagram to demonstrate 'Rotary forging, General forging machine (GFM) and Swaging' see article] Materials: Can rotary forge or swage most forgeable materials. Some “difficult-to-forge” materials by conventional...

...multiple punches and dies. Multi-stage transfer presses (either mechanical or hydraulic) with up to 10 stations are used for long production runs (> 50,000 parts year-1) of small-to-medium sized artefacts such as brass caps for electric lights. Mainly mechanical presses up to 1000 tons in capacity are used for deep drawing. In some high speed operations, lubrication of...

...multiple therapeutic agents (Figure 1). Delivering drugs to the brain Because of their small size, gold nanoparticles can easily travel into target cells. We can use gold nanoparticles specifically to target cells to treat difficult areas of the body, such as the brain. The brain is a highly controlled and protected organ, since there are substances in the blood that may...
