@bentwings2 any specific adhesives you know, suitable for this application?

@brian thank you for suggestions. @david do you know of any such specific type strong double sided INDUSTRIAL GRADE tape? Suhrud G

@Mike I'm talking about incorporating this procedure on assembly line, windows will need curing time as well I suppose? I'm not an expert on assembly or manufacturing engineering, so is that feasible?

@ BrianPetersen I know normally polyurethane is used, my question was also about process. In mass production you will at least need a robot to apply glue/polyurethane along its periphery as doing manually will consume a lot of man hours. Is there any easy way to do the same or any substitute idea?

It is a bus body and I want the fitting to be done as per the image. Any inputs where to start from? https://files.engineering.com/getfile.aspx?folder=18d6d02c-6bd9-4fd9-9901-e972469a28b6&file=Windows.jpg

I want to mount rear window flush with the surface of the body. with the current design the rubber rails/seals project out of the body. What is method or process to achieve what I'm looking for? Directly bonding can be a way but that will make window susceptible to cracking? Please let me know...

@compositepro thanks! looks like I'll meet my requirement but cost will significantly go high for this plastic overmolding process?

@Pud With plastics i.e. with Nylon 6 same part is costing me $40 and with uPVC it is costing around $20 against $70 for SS . Nylon 6 30% GF brought me closer to the required strength but not up to the mark, other plastics with higher strength are costing nearly the same as SS or even more. So...

@ornerynorsk my purpose was to reduce cost by replacing steel frame with plastic one, looks like I'm running out of luck.

@Pud Thanks, pultruded fiber glass would serve my purpose stiffness wise but I'm not sure about the pricing.

How do you think acetal copolymer would do?

I did increase the thickness as much as I could but being door frame, not able to increase outside diameter, hence looking for better plastic materials to compensate for flexural modulus for slightly thicker and better cross section than SS.

I'm working on replacing a steel door frame with a plastic one and looking for high stiffness plastic material which can sustain 50 lbs load without deflecting more than 5". I tried doing analysis on sides tubes of frame (80" long) using uPVC (extruded quality) and results were not so good...
