Powder coating is a popular finish used for functional and decorative purposes on products ranging from outdoor machinery to household items. Measuring the thickness of applied powder coating is a critical requirement for custom coaters and those performing incoming inspection of finished goods. Fischer instruments utilising the magnetic induction and eddy current methods are the instruments of choice for powder coating thickness measurement.
Powder Coating is applied globally to everything from lawn and garden equipment to furniture, appliance, and automotive components. The thickness of the powder coating applied determines how long the part will last, the part’s appearance and even in some cases the part’s colour. Proper measurement of the thickness therefore is critical.
In today’s competitive climate it is extremely important for anyone applying a coating to adhere to the thickness specification. Monitoring powder coating thickness with Fischer handheld coating thickness gauges will ensure this and also potentially save tens of thousands of Euro in costs. Table 1 shows how using a Fischer gauge can provide cost savings based on annual powder purchases.
| Film Thickness |
| Cost Savings |
based on annual
|10,000 €||50,000 €||250,000 €||1,000,000 €|
Note in Table 1 that increments such as 1 µm if measured and controlled properly can provide a significant reduction in costs thus making the custom coater more competitive.
However, only instruments with superior repeatability precision allow for the reliable measurement to this level. Likewise, utilising certified foils to adjust and verify gauge accuracy, something that comes included with the scope of supply of Fischer instruments vs. non-precise shims will provide the trueness necessary to monitor and adjust a powder coating line properly.
Because powder coating is applied to such diverse parts, selecting the most appropriate instrument and probe is highly important. Fischer offers a wide selection of instruments and probes starting with small, handy and robust DUALSCOPE® MP0 and MP0R pocket instruments up to the flexible FMP family with numerous interchangeable high-precision probes for the most demanding measurement tasks.
