If you don't have enough time to socialize, try to keep a conversation to them, in a short period of time you could make a gentle excuse to them for example,
Guys, I really need to go, I'm sorry I can't keep our convo longer... There's some problems I have to solve I so sorry.
Something like that, keep socializing into them even in short time
