In the world of automotive and aerospace design attention to detail is paramount, especially when it comes to creating components like backlit buttons. One of the key features enhancing user experience and safety is the use of day/night controls.
Day/night buttons and fascias are a design method used in the automotive industry to ensure visibility and functionality of buttons and controls in varying lighting conditions. This manufacturing process allows the symbols or graphics on buttons to be clearly visible during the day and subtly illuminated for effortless use in the dark to create an attractive ambience.
Painting and laser etching emerges as the ideal technique for creating day/night components. The precision and finesse achieved through laser technology ensure that graphics are crisp, clear and uniform. This method offers several advantages:
Precision and Consistency: Laser etching allows for intricate detailing with unparalleled precision, ensuring that graphics remain consistent across all buttons.
Durability: Painted and laser etched symbols are resilient and able to withstand the rigours of continuous use and exposure to varying environmental conditions, ensuring longevity. Technical paints have been optimised for abrasion resistance and adhesion.
Versatility: Painting and laser etching adapts effortlessly to various materials used in the automotive industry providing a versatile solution for different button types.
Speed and Efficiency: Laser technology enables swift and efficient etching processes contributing to the overall production efficiency. The graphic can be easily changed where there are many identical buttons in a fascia.
Non-contact Method: Being a non-contact method, laser etching minimises the risk of damage to the materials and ensures the integrity of the buttons.
Fimark has expertise in the production of backlit buttons and fascias for automotive dashboards. Close collaboration with moulders and first-tier suppliers enables the company to offer painting and laser etching services for these critical optical components.
Twenty years experience of the process has shown that, to be successful, both painting and etching need to be processes that take place in-house. Control of the paint thickness and subsequent laser setup have to be matched and consistency of paint thickness across batches and between batches of components is critical.
