We are setting up production to glue part of the loud speaker plastic
bracket to the speaker vibrating film together.

One part of plastic bracket is glue to nylon powder coated metal housing.

Another part of this plastic bracket is glue to vibrating polyester plastic
film.

Which adhesive supplier would you recommend?

Can you advise what is good adhesive for this application?

Thank you for your advises.

There seems to be a little something missing from your description of
the glue surfaces.
Care to share it with us?

Brian, actually, this is the same plastic bracket in between. One side of
bracket is glued to Nylon powder coated steel housing. The othe side of
bracket is glued to vibriating polyester film.

We are seeking the right kind adhesive for production to apply on both side
of this plastic bracket.

Ah, I see I was too oblique: you mentioned the plastic polyester film,
and the plastic nylon powder coat, but not the plastic of which the
bracket is made. There are solvent glues, hot glues and reactive or
two part glues. You have doubtless already tested epoxy, hot glue,
instant glue, and foam polyurethane of the kinds you can buy in a
hardware store. Plastics are difficult - a mechanically abraded
surface can help the bond.

The steel housing has nylon powder coating.
The plastic bracket is ABS.
The vibrating film is PET polyester film.

These three material are sandwiched together.
The glue areas is much too large for welding. Also, do not allow for
one to one welding.

Depends on how much mechanical load is actually applied to these
two interfaces, but I doubt that you can achieve a decent adhesion
with any affordable glue, because PA-ABS and ABS-PET are too
dissimilar plastic combinations!

Is perhaps mechanical assembly a choise for you, like screws,
rivets, clamps, snap fittings etc...?


No, I am told we must use glue.
Any mechanical assembly will distort the reproduction of sound.

Where can I find out more about glue os ABS-PET and ABS to Nylon?

What is PA, Nylon powder?

At this point, I would go to an adhesives supplier or manufacturer. For
example go to the 3M site, go to contact 3M, and ask if they supply
anything that will do the job. Also ask if there is an adhesive that
will bond your primary substrates to a third substrate. You could then
use an intermediate ring to form the bond.

Case there was a hole right thru , would there be room for a cast
rivit ?
