Introduction: In architectural manufacturing, precision is not just a goal; it is a requirement. Quality control in aluminum extrusion ensures that every profile delivered to a construction site meets the exact mechanical and aesthetic standards required for high-performance facades.
1. Dimensional Accuracy and Tolerance:
- Every extruded profile must undergo rigorous measurement to ensure it matches the technical drawings.
- Using advanced laser scanning and manual calipers, technicians check for “twist,” “straightness,” and wall thickness to ensure a perfect fit during on-site assembly.
2. Surface Integrity and Finish Quality:
- Visual inspections are conducted immediately after the cooling process to detect any surface defects like die lines or pitting.
- For anodized or powder-coated profiles, color consistency and coating thickness are tested to ensure the facade maintains a uniform appearance under various lighting conditions.
3. Mechanical Testing:
- Samples from each production batch are tested for hardness and tensile strength.
- This step confirms that the aluminum alloy has been tempered correctly and can withstand the structural wind loads and environmental stresses it will face in the field.
Conclusion: A facade is only as strong as its weakest profile. At Alumna, our comprehensive quality control protocols ensure that our aluminum systems provide peace of mind to architects and developers through unmatched reliability.
