  • Acrylic display windows

    In the FAQ section of this website it says that I can add a display window to my panel by using a rectangle-in-rectangle shape. I have a 16" x 5" x 0.125" black anodized aluminum panel to which I'd like to add a tinted display window. Can you help me with the following questions please:

     

    1. What thicknesses of acrylic do you offer?

    2. What tints of acrylic are available?

    3. How do I specify my choice in the Front Panel software?

     

    Many thanks,

    Carl

    Can the Plexiglass Red Filter you offer be used

    for VFD or LED Display Filters.?

    We offer the brand Plexiglas GS from Evionik (Product description) for both clear and red acrylics.

     

    You can find the optical properties on page 6. It has a pretty good transmittance percentage of 92 and blocks UV. Basically, it depends on what kind of filter you are looking for. There are acrylics available on the market with integrated light guiding material or non glare surface texture.

     

    If you are looking for UV protection and a couple of percent in transmittance loss aren't a problem, our plexiglas will be usable as VFD or LED display filters.

    (1) For transparent/translucent plastic materials , pLease add Clear Lexan (Polycarbonate) material to your available materials. In many instances the proximity of a polystrene or plexiglass material to an lcd or other electronics can build up a static charge and transmit it to the lcd/electronics ,possibly zapping it.

    (2) For Opague plastic materials ,please add ABS materials like black. No issues with static unlike Plexiglass/POlystyrene materials.

    Hello Jeff,

     

    I can sympathize with you in regards to static discharge. Having worked for many years in the plastics industry, I can offer some insight.

     

    Both polycarbonate and acrylic will have immense static discharge potential, but this appears to be more of an issue with the masking that is placed over the sheet. A sheet with poly-mask will have immense discharge capability (I have experienced a 1/4" arc from a sheet of 3mm polycarbonate), while a sheet with paper masking tends to have almost none. At Front Panel Express, we always remove the masking on any sheet we machine, and it sits on a giant grounded metal mill for significant periods of time. When the plastic is packed, if two pieces of plastic are to be packed one on top of the other, a piece of tissue paper will be placed between them. I would imagine, however, that a material like FPVC might still have issues, even with those efforts taken.

     

    We are able to machine plenty of different opaque plastic materials, and we can special order these quite easily. For the amount of this type of machining that we do, it does not make a ton of sense to keep all of these materials around. For something like black ABS, you will typically see one day added to your order for us to receive the material.

     

    Many thanks,

    -Paul
