The Manufacturing Process

Metal Frames

Good quality metal frames can involve up to eighty different steps in order to produce them.  Some metals such as titanium are even more complex. A typical metal frame can take up to four months to manufacture. In general, metal is lightweight, strong, flexible and anti-corrosive, making them ideal for frame production.  

Monel
Monel is an alloy, a mixture of two or more metals.  It's highly rust resistant, flexible and stronger than steel. 

Titanium Frames
Titanium is grey in colour and the lightest of all the metal frames.  When combined with modern day plastic lenses it makes for a very comfortable pair of glasses.  It is corrosion resistant, hypoallergenic and can be produced in a variety of colours. Pure titanium is expensive and as a result, it is typically blended with nickel or copper to product a titanium alloy for greater affordability.  Flexon is a proprietary titanium-alloy and 'memory material' that enables the wearer to twist, bend and crush the frame without affecting it's shape.   
To find Flexon stockists and other titanium brands including TITANflex and REFLEX memory eyewear, search theProVision brand finder.

Aluminium Frames
Aluminium itself is a naturally soft material and is often combined with silicon and iron to make the frame strong and hard. Aluminium frames have a very distinctive look and are often used in the construction of high end frames as they are lightweight and resistant to corroding.

Stainless Steel
Stainless steel is made from a blend of steel and chromium, making it a very strong metal with an element of flexibility that is easily accessible and well priced. While it weighs more than titanium it can be made very thin, thus reducing its weight. It will not corrode and is nickel free, again making it hypoallergenic which is good for those with sensitive skin.
