Upset Forging

We can forge bar stock as small as 1/4" up to 1-1/2" diameter, in almost unlimited lengths. We upset forge bar stock to create custom fasteners and specialty tools that require very high material strengths. The heads of the fasteners are created in open-die forges.

The main advantage of hot forging is that as the metal is deformed work hardening effects are negated by the recrystallization process. Upset forging changes the molecular structure of the material being forged, aligning the grain flow, and eliminating material weaknesses. Rods, pinions, bolts, and other components created through upset forging exhibit higher levels of strength and soundness, resisting deformation and breakage during use.

Most upset forged parts require additional operations to make them acceptable for their intended use. Modform, in concert with our parent, CMT,llc, performs the majority of these operations in house.
