Chemical Processes
Most plastics react when exposed to laser marking radiation. The resulting mark depends on the type of reaction – typically melting, foaming and bleaching, which is a function of the composition and colour of the base material. Additives may be used to enhance the colour change or produce a change to a specific colour.
Electrox laser marking equipment is used extensively in many chemical marking applications and can be achieved with the following laser marking systems from Electrox:
