Hello I would say that both sentences put across the message, that something is usually made in order to be turned down/away. They both show this, but one is slightly more formal in the use of English. BEING sounds more formal than TO GET. However to make this sense sound more correct. "It is usually formulated for the express purpose TO BE rejected." That's my interpretation. Hope this helps!

Hi there! Well sorry for confusion. Let me try to clear it up. Yes, I'd say TO BE is the most formal way, and also that this is more of a STATEMENT and a given FACT that this particular thing WILL BE rejected, no two ways about it. If this is the message you intend to give I'd select to be. For this certain statement. Of being I would say is not wrong, but it does not come across as well, or as certain as TO BE. Say both sentences out loud, I hope you find that TO BE sounds a little more natural, and correct when you pronounce the sentence......???
