Are new replacement hinges for Lenovo Edge 2 1580 supposed to move?

The left hinge on my Lenovo Edge 2 1580 is broken. I ordered new hinges by factory part number. When I received the new hinges I found that they would not move. I exerted a fair amount of force (I didn’t want to use to much for fear of breaking them) to try and open the hinges, but they would not budge. I need to know if this is normal for new hinges and if there is anything I can do to loosen them up. Thanks
