Surface Defect Detection for Die Cast Components
Die cast component inspection is a surface defect detection application that checks aluminium and zinc die cast parts for surface cracks, porosity breakout and cold shuts, using the same imaging approach TARKO applies to machined metal parts.
The problem
Die cast parts can carry internal porosity that breaks out at the surface, cold shuts where two flows of metal did not fully fuse, and surface cracks from the casting or trimming process. These defects can be small, low contrast, and easy to miss under manual inspection, particularly on parts with complex geometry.
How it works
TARKO's software analyzes images of the part's cast surfaces and checks for the crack, porosity and cold shut patterns it has been trained to recognize on the customer's own parts. The detection method itself is proprietary and not published.
The system is built to run inference locally, without depending on a cloud connection to make a pass or fail decision.
Where this applies
A growing use case is aluminium die castings for electric vehicles, such as battery housings and busbar castings. These parts are aluminium die castings, so the relevant defect classes overlap closely with what TARKO targets on other cast and machined metal parts.
What This Surface Defect Detection Application Catches
- Surface cracks on cast components
- Porosity breakout visible at the surface
- Cold shuts and incomplete metal fusion at the surface
Does this work on both aluminium and zinc die castings?
The imaging approach applies to both. Exact defect sensitivity depends on surface finish, part geometry and casting alloy, and is confirmed during a feasibility audit.
Is this specific to EV battery housings?
No. Battery housings and busbar castings are one example, because they are aluminium die castings with defect classes that match what TARKO targets. The application applies to die cast components generally.
