Defined Requirements
Inspection must relate to approved drawings and specifications.
Quality Control
Quality Control for Custom Metal Parts and Assemblies
Quality begins with defined requirements, current drawings and appropriate checks during production.
Quality Principles
In-Process Checks
Relevant characteristics are reviewed during production, not only at the end.
Functional Priorities
Critical interfaces receive attention according to product risk.
Inspection Stages
Drawing and Revision Review
Confirm the correct production documents.
Incoming Material
Review material specification and applicable documents.
First-Piece and In-Process
Check critical characteristics at useful production stages.
Final Inspection
Review dimensions, appearance, assembly and identification as agreed.
Process-Specific Controls
Sheet Metal and Bending
Feature locations, bend angles, formed dimensions and edges.
CNC Machining
Datums, bores, threads and critical dimensions.
Welding
Fit-up, joint location, visual condition and key dimensions.
Enclosures and Assembly
Panel fit, hardware, mounting interfaces and overall dimensions.
