I have an LCD touch screen in a bezel that I currently machine out of P95 matte acrylic(see black material image attached). It is low volume for this faceplate, maybe a few hundred a year so it does not warrant an injection mold expense. I CNC the faceplate, including a recessed area on the rear for the LCD to sit in a pocket. There is a slot at the top for a gesture sensor. I just looks cheap, I need some ideas on a material that can be machined that looks much nicer. As one option, on the bottom of the image I show an overlay that I have made by a company for another product. It looks better, but it is adhesive backed and there is always the risk of not aligning when installing the overlay or depending on possible improper handling, someone might peel it on a corner. Since the slots and recess have to be CNC'd, stainless is not an option for me as it is a pain to machine and requires coolant on the tools. I once used anodized aluminum and that can look nice but it is too labor intensive and time consuming to send out for finish.
This looks nice:
I included some images of nice looking faceplates. Maybe someone has some ideas on how to do this economically. I can have an injection mold make by a guy I know for a few grand, but he can never get the finish to look like these images, as he does not specialize in consumer injection where the finish is a big concern.
If I could just find the material being used for some of the simple white bezels shown then I might be able to CNC the border and cutout and be OK. But I can't find this anywhere. Typically ABS is used in injection. But sheet material never looks as good as these images.
