Abstract
A ram (40,50) of a press comprises metal sleeve (41,51), a hollow core (42, 58), a first end piece 42A, 52 attached to one end of the rod and a second end piece 46, 54 attached to the other end 47 of the ram to support a tool, the hollowcore being made of a material lighter than that of the sleeve. The benefit is a ram of reduced weight to minimize inertia forces arising during use.
