Surface finish standards

Surface finish in sheet metal fabrication affects far more than appearance. Controlled roughness, coating quality, and edge condition directly influence assembly accuracy, corrosion resistance, cleanliness, and regulatory compliance.

Weld integrity inspection

Weld integrity inspection ensures structural strength, dimensional stability, and cosmetic quality in sheet metal assemblies. This article explains common weld defects, inspection methods, HAZ control, and how Rollyu Precision integrates multi-stage weld inspection to meet ISO 9001 and ISO 13485 requirements.

Critical dimension checks

In precision sheet metal fabrication, not all dimensions carry equal importance. Critical dimensions—such as material thickness, hole location, flatness, bend angles, and fastener seating—directly affect assembly fit, functional performance, and regulatory compliance.

Tools used: CMMs, height gauges, pin gauges

Precision measurement is essential to stable sheet metal fabrication. This article explains how CMMs, height gauges, and pin gauges are applied throughout cutting, forming, fastening, and finishing to control dimensional accuracy, reduce variation, and support ISO 9001 and ISO 13485 compliance.

Quality Control & Inspection

Quality assurance in sheet metal is a multi-stage system, not a final checkpoint. This article covers inspection from material traceability to cutting, bending, welding, fastener installation, finishing, and final CMM verification—helping reduce scrap, rework, and risk while supporting ISO 9001/13485 compliance.
