How to attach a glass window onto a injected part
How to attach a glass window onto a injected part
(OP)
Hi everyone,
I'm designing a device in a startup (so we basically have little amount of money to spend) and I have to attach a rectangular and flat glass window onto an ABS/PC injected part (also flat). I'm currently thinking about a double coated adhesive + silk screen onto the glass (for aesthetic purpose) but the problem is that it costs a lot of money (laser cut the glass, die cut and apply the adhesive). Would you guys have another idea than using adhesive in order to attach a glass window onto an injected part? The shapes are simple: rectangular glass window and rectangular frame in the plastic part.
This is my first post so don't judge me too quickly ;)
Thanks in advance
César

Are the corners rounded, or sharp pointed 90 degrees?
T molding.

Please describe the "rectangular frame in the plastic part."
If I picture the molded-in frame correctly ( which without pictures and drawings is REEEEAALLY hard to do) could the frame be reversed so the attaching ugliness be hidden on the inside?

I attached a rough drawing of the current design: the rectangle (21.9x12.4) is the glass window while the crosshatched area represents the tape we currently use. We're planning on producing between 5000 and 10,000 part per year. We don't know the cycle time yet because it depends on the glass window production/assembly processes.
Thanks in advance guys. You help a lot :)

Adhesives like Hydtools suggested might be a good route. At 10,000 annual, that's only 40 a day. Modern car windshields are attached with adhesives as well, that are not UV cured. Manually applying an adhesive and cleaning up the product of messy goop and smears is easily achievable. Maybe look into:
