More Details
Why This Prototype Was Needed
Side-suction range hoods must capture oil fumes before they diffuse into the kitchen space.
This requires precise validation of:
- Airflow path and suction efficiency
- Oil smoke capture performance
- Structural sealing to prevent leakage
- Noise and vibration during operation
👉 Direct production without prototyping is high risk because:
- Airflow performance is invisible but critical
- Oil smoke behavior is difficult to predict
- Multi-part metal structure affects sealing and noise
- External appearance must match modern kitchen standards
Core Engineering Uncertainties
- Airflow Efficiency vs Noise Control: Higher suction may introduce noise and vibration issues
- Guide Panel Angle vs Smoke Capture: Incorrect angle reduces capture efficiency significantly
- Structural Sealing vs Assembly Complexity: Poor sealing leads to airflow loss and oil leakage
- Metal Surface vs Cleanability: Brushed metal must balance aesthetics with ease of cleaning
Why This Process Combination Was Chosen
We applied a functional-first prototyping strategy:
- Sheet Metal Fabrication → Real airflow structure and housing
- CNC Machining → Precision mounting and critical interfaces
- Surface Finishing → Brushed metal appearance simulation
👉 This ensures the prototype behaves close to final production conditions.
