As the key component in applications like transformers, inductors, motors, speakers, electromagnets and others, the magnet wire (also known as winding wire / enameled wire) is required with high accuracy as those wires are coated with very thin layer of insulation.

Conventional diameter control systems are using technique of laser scanning, good products with strong R&D team are capable to provide acceptable accuracy (normally +/- 0.3 µm) and repeatability (normally +/- 0.15 µm), but most of other products cannot deliver such of performance, and worse, they may on high repair ratio.

Another technique is laser diffraction which was launched later to the market, and till the date, there are less than three brands providing. The laser diffraction micrometer delivers at least 2.5 times higher accuracy  (+/- 0.12 µm) and repeatability ( +/- 0.06 µm) than the best brand of laser scanning systems.

It is definitely the trend to use laser diffraction technique for magnet wire, as the down-stream users need such good quality wires for their products. You are off the list if you cannot deliver.

How do I know what technique the micrometer is using with?

A very easily and obviously way to identify is listen with your ear. If you hear noise like something rotating inside, it is laser scanning micrometer, because such technique needs rotating mirror to generate light streams. A higher scanning rate means a higher speed the mirror carrying motor rotates. Normally wire drawing machines are running 24/7, none of laser scanning micrometer afford of long durability without any calibration or replacement of key parts.

How is the durability of SCreate’s laser diameter gauge?

We sell 1300+ units per year, 60% of which are integrated with reputed wire drawing machines as value-added function and sold together by those machine manufacturers. The durability could be endorsed by those manufacturers and their users. Furthermore, for direct purchase from us or through sales channels, we offer one-year industry warranty and guarantee the units are lifetime maintenance free.
