Despite scoring six goals, Bony has been in and out of the starting lineup, but Vorm expects his teammate to feature more regularly during the next few months of the season.
The 29-year-old told the South Wales Evening Post: "I saw in the dressing room how extremely strong he looks. It's awesome. He looks like a beast, which is very scary.
"He does not play as much as he wants to, but he has six strikes to his name anyway. I am confident that he will be a key player shortly.
"He is a goalscoring machine in training, showing great finishing skills. He keeps his cool in front of goal and his shots are venomous. He is so strong, it's out of this world."
Bony signed for Swansea in a £12m deal from Vitesse Arnhem in the summer.
