Spray Frame Thickness Requirements of Luggage Hardware

There is no set standard for the thickness of the spray lacquer frame (electrophoretic coating) required for the Luggage hardware, but the following factors can be used as a

First.Luggage hardware industry norm thickness range

The thickness of the electrophoretic coating usually ranges from a few microns to several tens of microns, depending on the product requirements and the environment

For applications requiring higher corrosion and wear resistance, the coating thickness may be on the thicker side, e.g. some industries may require 60 to 70 microns or even more.

Second.Luggage hardware product-specific requirements

If we use the metal logos for high-end decoration or in special environments , thicker coatings will require to provide better protection and decoration.

Some application scenarios may specify coating thicknesses, such as the national specification GB/T 18593-2010, which specifies a spray thickness of 0.17 to 0.3 mm

Third.process parameter control

We can control the coating thickness by adjusting electrophoresis process parameters (such as. voltage, time, coating concentration and so on.).

In practice, the process parameters need to adjuster by the material properties, surface condition and target performance.

Fourth.Luggage hardware quality and performance balance

Too thick a coating may affect logo fineness, while too thin a coating may not meet protection requirements.

We recommend determining the optimum thickness range experimentally, considering appearance, durability, and processability.
