    • A laser-markable acrylic and PVC composition (commonly known as Kydex®) is lased using a CO2 laser to differentiate a laser etched graphic or pattern from the base material. A discoloration may be controlled to improve an appearance of the graphic or pattern. An embodiment uses a 500 to 2,500 watt CO2 laser to provide a raster or vector graphic pattern on the Kydex® finished part. Yet another embodiment is to use a 500 to 2,500 watt CO2 laser to provide a seamless raster or vector graphic pattern on a large piece of Kydex® which can then be cut and divided into multiple finished parts. In this case, an embodiment would include providing the necessary software and process controls to insure that the seams between individual parts that make up a larger part are without lines of demarcation.
    • 激光可标记的丙烯酸和PVC组合物(通常称为Kydex®)使用CO2激光器进行激光,以将激光蚀刻的图案或图案与基材分离。 可以控制变色以改善图形或图案的外观。 一个实施例使用500至2,500瓦的二氧化碳激光器在Kydex®成品部件上提供光栅或矢量图形图案。 另一个实施例是使用500至2,500瓦的二氧化碳激光器,在大片Kydex上提供无缝光栅或矢量图形图案,然后将其切割并分成多个成品部件。 在这种情况下,一个实施例将包括提供必要的软件和过程控制以确保构成较大部分的各个部分之间的接缝不具有划线线。
