After the Second World War, there was exponential growth in the use of plastic in manufacturing. This resinous, malleable and yet incredibly durable material can be moulded into a huge range of shapes and forms, making many of the products we now use on a daily basis.

10 Creative Uses for CNC Machinery

CNC machines are machining tools controlled by computers. Traditionally CNC machining is used to shape pieces of metal or other rigid materials – for example, to make parts for cabinets, boats or cars. Some creative types have used their CNC routers to make things that are unexpected

Interesting Storage Methods You Never Knew Existed

People have invented innovative methods for storing everything from energy and water, to industrial waste, data and personal belongings. Pumped-storage hydroelectricity Pumped-storage hydroelectricity (PSH) is a method for storing capacity and then generating electrical power during periods of high demand. It uses water that’s pumped from a

Abandoned Machines

As a copy writer for Hans Von Der Heyde, a team of industrial engineers who design and build cutting edge machinery, I often come across beautiful photographs of old, derelict machinery when looking for imagery of more modern machines. This contrast between new and old has sparked
