Why Impact
Impact extrusion is a fast, efficient, and repeatable production process capable of producing up to 5,000 parts per hour, depending on size and complexity. The process produces parts free of flash, material pickup, or parting lines, often requiring little secondary machining.
Impact extrusions offer:
- Near-net shaping to minimize material waste
- Superior dimensional precision and tight tolerances
- Low tooling costs compared to other metal forming methods
- High strength and structural integrity from dense, uniform grain structure
These advantages make impact extrusion ideal for high or low volume where quality and efficiency are critical.
WHAT IS IMPACTING
Impact extrusion is a cold forming process in which a lubricated metal slug is placed into a die cavity and struck by a punch. The force of the punch causes the metal to flow through the die opening, forming a near-net shape in a single, high-speed stroke. The process is typically carried out using hydraulic or mechanical presses.

REVERSE EXTRUSION
Metal flows backward around the punch—opposite the direction of force. This method allows for a wider variety of shapes and simplifies tooling by matching the part shape to the punch.
FORWARD EXTRUSION
The punch drives the slug downward through a tight-fitting die opening, forcing metal to flow in the same direction as the punch. Ideal for parts with longer lengths or thinner sections, this process ensures consistent, unidirectional grain flow.
COMBINATION EXTRUSION
A hybrid of reverse and forward methods, this process forms complex geometries with tighter tolerances, utilizing multiple flow directions to meet advanced design requirements.
