One-die two-stroke cold forging machine: mainly used for small head
deformation, simple products, relatively low cost, and high
production efficiency. Common such as: rivets, countersunk screws,
slotted screws.
Two-die three-stroke cold forging machine: mainly used for large
deformation of the head, short rod, and multi-step special-shaped
parts.
Three-die three-stroke cold forging machine: mainly used for
hexagon head bolts, cylindrical head hexagon socket bolts, and
relatively simple products.
Two-die four-stroke cold forging machine: mainly used for large
deformation of the head, short rod, and multi-step special-shaped
parts.
Four-die four-stroke cold forging machine, five-die five-stroke
cold forging machine, six-die six-stroke cold forging machine:
mainly used for products with large head deformation and more
complex special-shaped parts.
