Welcome to the Forum. I would call it swaged. You could use a variety of machines and tools depending on production quantities. You would need to calculate the tonnage required for the material size and Grade.
For low quantities you could use common hydraulic bearing press with a suitably machined, hardened and tempered forming tool.
For medium quantities you could use a hand fed Benchmaster style press with above-mention forming tool.
For higher quantities you would need an automated feeding system.
