Hammer Forging

Hammer Forging is a type of closed-die forging, which is the process of striking a preheated piece of metal with a large, fast-moving press, called a Hammer.  The metal is shaped in an impression die through multiple blows to achieve the desired shape.  A wide variety of components can be produced with superior strength and durability from the hammer forging process. 


All forgings are cleaned, deburred, and ground as necessary to remove rust, sharp corners, and edges from a part.  The forgings are delivered with a clean, uniform surface.  Parts can be further protected with a rust preventative or delivered in a bag that inhibits rust.


Coining is a process that allows tighter tolerances for specific applications by pressing a forged part to a particular dimension.

Mag Particle Inspection

MPI is a non-destructive testing method to locate surface defect on steel forgings.  This process is critical for some forgings that are machined and used for critical load bearing applications.
