How Does Electroplating Work?

electroplating

While there is no magic trick to change common chemical elements into rare and valuable ones, electroplating is as close as it gets. Electroplating is similar to electrolysis which is the opposite of the process batteries use to produce electric currents. The earliest form, which became the modern electroplating process, occurred in the early 19th century.

The development of bigger electric generators meant higher currents which drastically improved the process. Advancements in industrial and manufacturing practices over the past two centuries have changed this process considerably.

While some of you may already know what electroplating is, what about how it works? Continue reading

We can never get tired of reading and writing about engineering developments, emerging technologies and the flying taxi. This year has already seen a few interesting concepts from Uber signing with NASA to the CityHawk and Pal-V. And now it is time for Audi to step up to the plate.

The German automaker is living up to their name with the new Pop.Up Next, a hybrid quadcopter and compact two-seater electric vehicle. This is certainly an ambitious attempt but one that seems well worth it considering their partnership with Italdesign and Airbus. Continue reading

CNC Machining And 3D Printing In Manufacturing

CNC machining

In modern-day manufacturing, technology is forever advancing and it is essential to keep up with the all latest trends. Throughout our history, we have seen a number of methods implemented to manufacture custom parts. Today, CNC machining and 3D printing are seen as two of the most widely used manufacturing processes.

With the rapid growth of 3D printing technology, some believe it has become the first choice for many industries. On the other hand, CNC machining is still considered a reliable standard and there really aren’t many things that don’t involve CNC machined parts somewhere in the process.

Looking at the available technologies and industries utilising CNC machining and 3D printing, how do they work? Which industries prefer one or the other and how do they compare? Continue reading

China continues to impress with their latest innovation, new stealth combat drones known as Tian Ying (CH-7). It featured at the air show in Zhuhai, a biannual event that showcases China’s latest developments in military and civilian aviation. There were several Chinese state-owned arms companies also displaying their drones. It appears China is investing heavily in unmanned aircraft with plans to develop drones capable of flying from one of its future aircraft carriers. Could this be a role for the CH-7 to fulfil?

According to China’s Ministry of Industry and Information Technology, more than 350 private Chinese firms are now capable of making unmanned aerial, surface or ground vehicles. Continue reading

Military Vehicles And Robotics Through The Ages

Military vehicles and robots date as far back as WWI with small, remote-controlled and tracked, disposable explosive devices. WWII saw even more innovative designs with the Soviet Army developing full-sized remote-controlled tanks between 1930 and 1940. Even the Brits had a hand in remote controlled tanks with their Matilda MK2 Infantry tank, the ‘Black Prince’.

While nothing compares to modern day military vehicles and autonomous systems, our history is filled with incredible engineering feats. With so many different autonomous military vehicles and systems, we’re only focusing on a few of the standouts. Continue reading
