The South Korean sent half of their national team to Kazan and gained an upper hand over their Chinese opponents who have only one Olympic champion in the team.
The Koreans won the women's singles and doubles, men's doubles, mixed doubles and the team event titles, mostly beating their Chinese counterparts in the finals.
With the badminton golds they won on Thursday, South Korea jumped to the second place on medal table with 12 gold medals, 60 shy of that won by run-away leader Russia.
Japan places third on medal table with 10 gold, followed by China with 9.
With six more matchdays to go and 190 gold medals to be contested, hosts Russia will certainly break the all-time high record of 75 gold medals won by a nation at the Universiade set by China two years ago in Shenzhen, China.
Kazan Universiade features in 351 events of 27 sports and will conclude on July 17.
