With several decades of experience in advanced finishing, Extrude Hone understands the requirements specific to die casting, where deburring quality directly impacts component performance and reliability.
Our solutions deliver repeatable, controlled results on complex geometries that conventional methods cannot reliably handle.
Comparison between conventional methods and the thermal energy method (TEM)
| Criteria | Manual polishing / deburring | Vibratory finishing | Shot blasting | Robotic finishing | TEM |
| Processing rate | Low: entirely dependent on the operator's pace | Moderate: batch processing, but long cycles | High on exposed surfaces, but limited to what the jet can reach | Moderate to low: batch processing, but long cycles | High: 30 to 60 seconds per cycle, several parts at once |
| Access to internal / complex areas | Limited to areas visible and accessible to the tool | Effective on external surfaces, poorly effective internally | Line-of-sight process: cannot reach hidden passages | Effective on external surfaces, hardly effective internally. | Treats internal and external surfaces simultaneously, including inaccessible passages |
| Consistency of results | Variable, dependent on operator skill | Adequate on simple parts, uneven on complex geometries | Good on accessible areas only | Adequate mostly for simple parts. | Consistent and repeatable, regardless of volume processed |
| Labour required | Very high, repeated part-by-part handling | Moderate: loading, unloading and settings | Moderate: process setup and control | Intensive settings | Low: automated process, reduced dependence on the operator |
| Effect on the material | Risk of local marking or material removal | Risk of uncontrolled edge rounding from wear over time | Can alter surface finish and generate residual stress | Minimum but dependent on tool wear or abrasive band wear. | No adverse effect on the material, microstructure or surface finish, on aluminium, zinc and zamak |
Full process automation removes operator dependency and eliminates variability, ensuring stable quality throughout production. This results in:
- Consistent output at scale
- Reduced reliance on manual expertise
- Stable, repeatable quality over long production runs
Designed for industrial performance, our solutions achieve very short cycle times, often under one minute, while maintaining high stability from prototype to full-scale production.
