Using abrasive flow machining, Extrude Hone AFM can smooth and refine internal intake passages by forcing abrasive-filled polymer media through the manifold under controlled pressure.
The process is suitable for many gasoline, diesel, naturally aspirated, and forced-induction applications where internal airflow and runner condition matter.
Why Intake Flow Matters
An internal combustion engine relies on moving enough air into the cylinders to support combustion.
The intake manifold is a major part of that pathway.
Rough casting texture, uneven transitions, restrictive bends, and other irregularities can interfere with flow.
Porting is intended to improve that pathway.
AFM can address internal surfaces throughout the runner, including locations that may be impossible to reach reliably with conventional porting tools.
Intake Manifold Porting With Abrasive Flow Machining
The AFM media is semi-solid and contains abrasive particles.
Hydraulic force pushes it through the manifold.
As it squeezes through restricted regions, the media removes controlled amounts of material and smooths internal surfaces.
The process is customized through:
- Abrasive particle size
- Abrasive concentration
- Media characteristics
- Hydraulic pressure
- Tooling
- Number of cycles
- Workpiece material
This allows Extrude Hone AFM to develop a porting process around the actual component.
Gasoline, Diesel, and Turbo Applications
Houston has a large automotive and truck community that includes diesel performance, turbocharged applications, racing, off-road vehicles, custom trucks, performance street cars, and restoration.
AFM may be useful across many of these configurations.
Extrude Hone AFM's automotive materials specifically identify diesel and turbocharged engines among the engine types suitable for AFM. Intake manifolds are one of the most frequently processed components.Potential Flow Improvements
In suitable intake-manifold applications, Extrude Hone AFM reports flow improvements of up to approximately 25 percent.
Improved flow may help support:
- Better cylinder filling
- Improved volumetric efficiency
- Increased horsepower
- Increased torque
- More responsive engine operation
- Improved combustion efficiency
These results depend on the entire engine system.
A restrictive cylinder head, turbo setup, exhaust system, or fuel-delivery issue can limit the performance benefit of an improved manifold.
AFM vs. Traditional Porting
Hand porting is inherently dependent on access.
Many modern intake manifolds contain runners that curve deeply inside the casting, making portions of the passage difficult to see or reach.
AFM does not require a technician to physically put a grinder against each surface.
The abrasive media follows the passage itself.
This can reduce the risk of localized ripples or uneven internal treatment associated with inconsistent access.
Aluminum and Cast-Iron Manifolds
Intake manifolds may be produced from aluminum, cast iron, or other materials.
Extrude Hone AFM adapts its media and abrasive strategy to the workpiece.Existing company guidance notes that aluminum generally calls for lighter abrasion while harder cast iron can use a more aggressive formulation.
Repeatable Processing
For manufacturers or engine builders working with multiple identical components, AFM can be repeated once tooling and processing variables are established.
That can help create more consistent internal finishing from component to component.
