As a general comment, use of the lower case and spacing between sentences/words would make your question easier to read.
As a specific comment, you stated that you contracted a manufacturer that gave you a recommendation but some unspecified "other people" told the manufacturer's recommendation would not work. Did they say why it wouldn't work? What is your criteria for deciding who to believe? If I said the manufacturer was right, does that hold more or less weight than the people who said it wouldn't? How would you know if I had any idea of what I was talking about? If someone else responds and says to use something different, how would you know that they know what they're talking about?
I'd recommend that you go back to the manufacturer and ask them about why they made their recommendation. Share with them the information you have as to why others feel it wouldn't work. Make an informed decision based on repeatable information, not on what somebody on the Internet told you.

RE: ACETAL-POLYAMIDE JOIN
Dear vpl thanks for your general comment i'll try to adjust. As far your specific comment i would like to say that many times manufacturers that don't have a product for the purpose you need it usually recommends the one closest to that even if it is not suitable.In that case the most safe way is by practical knowledge, two parts a little adhesive and test.That is what i was looking for. Some experience.
I would like to say that i tried the cyanoacrilate along with primer and i failed.i tried also epoxy and was a disaster. If someone had better luck it would be helpful for the future.

You may want to consider welding. Even simple hot plate welding - heat a piece of steel, touch the parts to it, then press the parts together. More sophisticated methods are available also, like ultrasonic welding.
