Hummingbird – the world’s lightest folding bike is ready for testing

Hummingbird bikeBritish motorsport company Prodrive announced this week that testing of the Hummingbird folding lightweight bike would begin in October, with anticipated production and sales starting early in 2017.

The Hummingbird is the concept of London based designer Petre Cracuin. Petre along with co-founder Ligia Stan has a passion for bikes and the project was born out of their desire to have a lightweight folding bike that was not only a pleasure to ride but was also easy to carry around and looked good. Despite having multiple bikes themselves, they realised there was nothing out there that fitted the bill so Petre set to work to solve the problem and the Hummingbird was born. A folding bike that is comfortable to ride, looks good, is easy to fold and carry and weighs in at an astounding 6.7kg. To put that in perspective, that’s the same as two normal weight domestic cats!

Reasons for coating busbars

coating busbarsThere are a few reason for plating or coating busbars. Cosmetic reasons or provision of insulation are a couple but the most common reason for coating busbars is to inhibit corrosion.

Busbars are commonly made from copper, which in itself is quite resistant to corrosion but busbars are often used in environments where higher levels of protection are needed. Over time, copper oxidises and can impact the surfaces conductive properties. So plating or coating busbars, not only reduces corrosion but also improves the longevity and conductive properties of the item. Continue reading

Osseointegration trial for military personnel in the UK

osseointegration_medical_imImprovements in manufacturing processes and capabilities allow for more complex and diverse solutions to be thought up for an increasing number of problems. The ability to cut and machine smaller and more complex parts using modern techniques like waterjet cutting, 3D printing and various multi axis machines, combined with software developments mean this is becoming increasingly evident in the medical and pharmaceutical world. The ability to make one off, custom implants and limb replacements for specific patient needs is opening up a whole new world. Continue reading

The versatility of waterjet cutting

waterjet cutting in acitonWaterjet cutting has really come to the forefront of manufacturing in recent years because of its versatility. There are an array of reasons to choose waterjet cutting over other methods, and they aren’t all about the actual cutting control. Improved efficiency in processes and reduced wastage and costs also factor highly, which by default leads to improved customer service.

Omni directional cutting, cutting widths, stress free cutting and improved finishing are all advantages of using water instead of more traditional cutting methods. However, one of the most fundamental things with waterjet cutting is that when you use water, there is no Heat Affected Zone (HAZ). This is the area around where you’re machining that gets hot because of the machining process. The heat generated in this area means the structure of the material gets altered and can be liable to fracture. If machining composite materials using traditional methods, the HAZ can cause all sorts of distortions and reactions, resulting in breakage and wastage. The ability to cut cold removes all these barriers and means that almost any material can now be cut with no alteration to its base structure. Continue reading

Benefits of Structural Steel Framed Construction

structural steel framed buildingThink of structural steel framed buildings and the sort of things that come to mind are probably, office sky scraper buildings or big warehouses and agricultural buildings. The sorts of thing you see in big cities or on the outskirts when new out of town shopping malls go up. But steel framed structures are commonly used across a whole range of construction projects; garages, residential housing and short term temporary structures all make good use of steel frame construction methods because they are durable, flexible, cost effective and sustainable.
