Most people know the increments of Km (kilometer), m (meter), cm (centimeter), and mm (millimeter), but do you know what is smaller than a millimeter?
We use _ (micron), _m (micrometer) and nm (nanometer) for those smaller objects.
To help you understand the size of these increments, we might compare them to the thickness of a human hair. The average thickness of a human hair is on the order of 0.2 mm. Therefore, that could be converted to the increments of 200_ (200_mm) or 200,000 nm. Generally, we are concerned with our waist size or how tall we are, but we never really stop to consider the fine width of even one small human hair. However, we at Extas are able to manipulate even these small sizes.
Extas handles plastics and resins. Even individual parts that have imperceptible discrepancies can cause unevenness when these parts are assembled, making enormous problems for the manufacturer. Such discrepancies can cause finished plastic products to crack at their seams (for example battery covers for remote controllers or cordless handsets for telephones), or can result in their buttons popping off (for example the buttons on cell phones). Extas takes great pride in providing superior designs to prevent such problems from occurring. In fact, we are proud to say that we can create anything in plastic or resin. |
